public class t1 { public static void main(String[] args) { int a = Integer.parseInt(args[0]); int b =Integer.parseInt(args[1]); System.out.println(a+b); } }

您好！根据您的代码，我注意到您想在控制台中接收两个整数参数，并将它们相加后打印出来。这是一个简单的Java程序。您在main方法中使用了args数组来接收命令行参数。但是需要注意的是，在运行此程序时，您需要在命令行中提供两个整数作为参数。

如果您想要在命令行中运行该程序并提供两个整数参数，可以使用以下命令：

javac t1.java
java t1 10 20

这将在控制台上打印出30，因为10 + 20 = 30。请确保在运行程序之前已经编译了Java文件（使用javac命令）。

如果您需要进一步的帮助，请随时提问！

将一下java代码转成c语言：import java.util.; public class Main { public static boolean judge(char c1,char c2) { char ch[] = {'#','+','-','','/','%','(',')'}; int num1 = 0,num2 = 0; for(int i = 0;i <= 7;i ++) { if(ch[i] == c1) num1 = i; if(ch[i] == c2) num2 = i; } if(num1 > num2) return true; return false; } public static int calculation(int t1,int t2,char c) { if(c == '+') return t2 + t1; else if(c == '-') return t2 - t1; else if(c == '*') return t2 * t1; else if(c == '%') return t2 % t1; else return t2 / t1; } public static void main(String[] args) { Scanner sc = new Scanner(System.in); String s = sc.nextLine(); Stack<Integer> stk_int = new Stack<>(); Stack<Character> stk_str = new Stack<>(); int index = 0; stk_str.push('#'); for(int i = 0;i < s.length();i ++) { if(s.charAt(i) < '0' || s.charAt(i) > '9') { if(index != i) stk_int.push(Integer.parseInt(s.substring(index,i))); index = i+1; boolean flag = false; while(flag == false) { if (judge(s.charAt(i),stk_str.peek())) { stk_str.push(s.charAt(i)); if(stk_str.peek() == '(' ) stk_str.push('#'); if( stk_str.peek() == ')') { stk_str.pop(); while(stk_str.peek()!='#') { stk_int.push(calculation(stk_int.pop(),stk_int.pop(),stk_str.pop())); } stk_str.pop(); stk_str.pop(); } flag = true; } else { stk_int.push(calculation(stk_int.pop(),stk_int.pop(),stk_str.pop())); } } } if(index != s.length() && i == s.length()-1) stk_int.push(Integer.parseInt(s.substring(index,s.length()))); } while(!stk_int.isEmpty() && stk_str.peek()!= '#') { stk_int.push(calculation(stk_int.pop(),stk_int.pop(),stk_str.pop())); } System.out.println(stk_int.pop()); } }

以下是将 Java 代码转换为 C 语言代码的结果：

                    top_int--;

            }
        }

        top_int--;
    }
    printf("%d\n", stk_int[top_int--]);
    return 0;
}

需要注意的是，Java 代码中使用了 Scanner 类来接收用户的输入，在 C 语言中需要使用 fgets 函数。此外，Java 中的 Stack 类可以使用数组来实现栈的功能。需要注意的是，C 语言中数组下标从 0 开始计数，而 Java 中数组下标从 1 开始计数，因此在转换过程中需要进行相应的调整。

import java.awt.*; import javax.swing.*; public class sdsds { public static void main(String[] args){ JFrame f=new JFrame("color"); f.setSize(600,500); f.setLocation(300, 200); f.setLayout(new GridLayout(2,1,10,20)); Panel p1=new Panel(); Panel p2=new Panel(); p1.setLayout(new GridLayout(3,4,20,20)); Label red=new Label("红色",Label.CENTER); red.setFont(new Font(Font.DIALOG,Font.BOLD,20)); red.setBackground(Color.red); Button bt1=new Button("+"); bt1.setFont(new Font(Font.DIALOG,Font.BOLD,20)); TextField t1=new TextField("220"); t1.setFont(new Font(Font.DIALOG,Font.BOLD,50)); Button bt5=new Button("-"); bt5.setFont(new Font(Font.DIALOG,Font.BOLD,20)); p1.add(red); p1.add(bt1); p1.add(t1); p1.add(bt5); Label green=new Label("绿色",Label.CENTER); green.setFont(new Font(Font.DIALOG,Font.BOLD,20)); green.setBackground(Color.green); Button bt2=new Button("+"); bt2.setFont(new Font(Font.DIALOG,Font.BOLD,20)); TextField t2=new TextField("220"); t2.setFont(new Font(Font.DIALOG,Font.BOLD,50)); Button bt6=new Button("-"); bt6.setFont(new Font(Font.DIALOG,Font.BOLD,20)); p1.add(green); p1.add(bt2); p1.add(t2); p1.add(bt6); Label blue=new Label("蓝色",Label.CENTER); blue.setFont(new Font(Font.DIALOG,Font.BOLD,20)); blue.setBackground(Color.blue); Button bt3=new Button("+"); bt3.setFont(new Font(Font.DIALOG,Font.BOLD,20)); TextField t3=new TextField("220"); t3.setFont(new Font(Font.DIALOG,Font.BOLD,50)); Button bt7=new Button("-"); bt7.setFont(new Font(Font.DIALOG,Font.BOLD,20)); p1.add(blue); p1.add(bt3); p1.add(t3); p1.add(bt7); p2.setBackground(new Color(255, 255, 0)); f.add(p1); f.add(p2); f.setVisible(true); } } 帮我在上面代码的基础上，实现点击加减按钮能改变颜色值中各色值的分量，下面面板的颜色同步改变

好的，你需要对代码进行一些修改。首先，你需要在每个加减按钮的监听器中获取当前颜色值的分量，然后根据加减操作改变分量值，并重新设置颜色。

下面是修改后的代码：

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class sdsds {
    public static void main(String[] args) {
        JFrame f = new JFrame("color");
        f.setSize(600, 500);
        f.setLocation(300, 200);
        f.setLayout(new GridLayout(2, 1, 10, 20));

        Panel p1 = new Panel();
        Panel p2 = new Panel();
        p1.setLayout(new GridLayout(3, 4, 20, 20));

        Label red = new Label("红色", Label.CENTER);
        red.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        red.setBackground(Color.red);
        Button bt1 = new Button("+");
        bt1.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        TextField t1 = new TextField("220");
        t1.setFont(new Font(Font.DIALOG, Font.BOLD, 50));
        Button bt5 = new Button("-");
        bt5.setFont(new Font(Font.DIALOG, Font.BOLD, 20));

        // 添加加减按钮的监听器
        bt1.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t1.getText());
                if (value < 255) {
                    value++;
                    t1.setText(String.valueOf(value));
                    red.setBackground(new Color(value, Integer.parseInt(t2.getText()), Integer.parseInt(t3.getText())));
                    p2.setBackground(new Color(value, Integer.parseInt(t2.getText()), Integer.parseInt(t3.getText())));
                }
            }
        });

        bt5.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t1.getText());
                if (value > 0) {
                    value--;
                    t1.setText(String.valueOf(value));
                    red.setBackground(new Color(value, Integer.parseInt(t2.getText()), Integer.parseInt(t3.getText())));
                    p2.setBackground(new Color(value, Integer.parseInt(t2.getText()), Integer.parseInt(t3.getText())));
                }
            }
        });

        p1.add(red);
        p1.add(bt1);
        p1.add(t1);
        p1.add(bt5);

        Label green = new Label("绿色", Label.CENTER);
        green.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        green.setBackground(Color.green);
        Button bt2 = new Button("+");
        bt2.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        TextField t2 = new TextField("220");
        t2.setFont(new Font(Font.DIALOG, Font.BOLD, 50));
        Button bt6 = new Button("-");
        bt6.setFont(new Font(Font.DIALOG, Font.BOLD, 20));

        bt2.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t2.getText());
                if (value < 255) {
                    value++;
                    t2.setText(String.valueOf(value));
                    green.setBackground(new Color(Integer.parseInt(t1.getText()), value, Integer.parseInt(t3.getText())));
                    p2.setBackground(new Color(Integer.parseInt(t1.getText()), value, Integer.parseInt(t3.getText())));
                }
            }
        });

        bt6.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t2.getText());
                if (value > 0) {
                    value--;
                    t2.setText(String.valueOf(value));
                    green.setBackground(new Color(Integer.parseInt(t1.getText()), value, Integer.parseInt(t3.getText())));
                    p2.setBackground(new Color(Integer.parseInt(t1.getText()), value, Integer.parseInt(t3.getText())));
                }
            }
        });

        p1.add(green);
        p1.add(bt2);
        p1.add(t2);
        p1.add(bt6);

        Label blue = new Label("蓝色", Label.CENTER);
        blue.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        blue.setBackground(Color.blue);
        Button bt3 = new Button("+");
        bt3.setFont(new Font(Font.DIALOG, Font.BOLD, 20));
        TextField t3 = new TextField("220");
        t3.setFont(new Font(Font.DIALOG, Font.BOLD, 50));
        Button bt7 = new Button("-");
        bt7.setFont(new Font(Font.DIALOG, Font.BOLD, 20));

        bt3.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t3.getText());
                if (value < 255) {
                    value++;
                    t3.setText(String.valueOf(value));
                    blue.setBackground(new Color(Integer.parseInt(t1.getText()), Integer.parseInt(t2.getText()), value));
                    p2.setBackground(new Color(Integer.parseInt(t1.getText()), Integer.parseInt(t2.getText()), value));
                }
            }
        });

        bt7.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                int value = Integer.parseInt(t3.getText());
                if (value > 0) {
                    value--;
                    t3.setText(String.valueOf(value));
                    blue.setBackground(new Color(Integer.parseInt(t1.getText()), Integer.parseInt(t2.getText()), value));
                    p2.setBackground(new Color(Integer.parseInt(t1.getText()), Integer.parseInt(t2.getText()), value));
                }
            }
        });

        p1.add(blue);
        p1.add(bt3);
        p1.add(t3);
        p1.add(bt7);

        p2.setBackground(new Color(255, 255, 0));

        f.add(p1);
        f.add(p2);
        f.setVisible(true);
    }
}

现在你可以运行代码并测试它。当你单击加减按钮时，颜色值的分量将随之改变，并且下面的面板颜色也会同步改变。
