import java.util.Scanner; import java.util.Stack; public class Kuohao { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String str = sc.next(); check(str); } public static void check(String str) { Stack<Character> stack = new Stack<Character>(); //循环该数组下标，栈为空进栈 for (int i = 0; i < str.length(); i++) { char c = str.charAt(i); if (stack.isEmpty()) { stack.push(c); } else { //当前的栈顶 char top = stack.peek(); //通过ascll码判断 if (top-c == -1 || top - c == -2) { stack.pop(); } else { stack.push(c); } } } //当栈为空时说明括号完全匹配 if (stack.isEmpty()) { System.out.println("Yes"); } else { System.out.println("No"); } } }

这是一段 Java 代码，用于检查一个字符串中的括号是否匹配。这个程序首先会读入一个字符串，然后调用 `check` 方法来检查其中的括号。`check` 方法使用一个栈来存储括号，并循环遍历字符串中的每个字符。如果当前栈为空，则将该字符进栈。否则，将栈顶元素与当前字符进行比较，如果它们是一对括号，则弹出栈顶元素，否则将当前字符进栈。最终，如果栈为空，则说明括号匹配，否则不匹配。

import java.util.Scanner; package base; public class scaner { public static void main(String[] args) { } } 改错

在代码的开头处移除多余的import语句，将package语句放在import语句后面，同时将类名从"scaner"改为"Scanner"，修正后的代码如下：

package base;
import java.util.Scanner;

public class ScannerExample {
    public static void main(String[] args) {
        // 在这里编写你的代码
    }
}

请注意，你需要在`main`方法中编写你的代码，这只是一个修正后的代码框架。

import java.util.Scanner;

As an AI language model, I cannot perform input/output operations or run Java code. However, here is an example of how the Scanner class can be used in Java to read user input from the console:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter your name: ");
        String name = scanner.nextLine();
        System.out.println("Hello, " + name + "!");
        scanner.close();
    }
}

In this example, we create a Scanner object to read input from the console using `System.in`. We then prompt the user to enter their name and read their input using the `nextLine()` method of the Scanner class. Finally, we print out a greeting using the user's name. Note that we close the Scanner object at the end to prevent resource leaks.
