package homework; public class Student { class Student{ private String name; private int stuNo; private String sex; private String grade; private double score; } public static void main(String[] args) { Student stu=new Student(); stu.name="Monkey"; stu.stuNo="000001"; stu.sex="man"; stu.grade="first grade"; stu.score="100.00"; System.out.println("姓名:"+stu.name+"学号:"+stu.stuNo+"性别:"+stu.sex+"班级:"+stu.grade+"成绩:"+stu.score+""); } }输出结果是什么

输出结果是：编译错误，因为在赋值时，stuNo和score应该是int和double类型，而不是String类型。正确的代码应该是：

public class Student{
private String name;
private int stuNo;
private String sex;
private String grade;
private double score;

public static void main(String[] args) {
Student stu=new Student();
stu.name="Monkey";
stu.stuNo=000001;
stu.sex="man";
stu.grade="first grade";
stu.score=100.00;
System.out.println("姓名:" + stu.name + " 学号:" + stu.stuNo + " 性别:" + stu.sex + " 班级:" + stu.grade + " 成绩:" + stu.score);
}
}

public class Student { public static void main(String[] args) { Student stu=new Student(); stu.name="Monkey"; stu.stuNo=1000001; stu.sex="man"; stu.grade="first grade"; stu.score=100.00; System.out.println("xingming:"+stu.name+"\nxuehao:"+stu.stuNo+"\nxingbie:"+stu.sex+"\nbanji:"+stu.grade+"\nchenji1:"+stu.score+""); } } class Student{ private String name; private int stuNo; private String sex; private String grade; private double score; }

这是一个关于 Java 编程的问题，我可以回答。这段代码定义了一个名为 Student 的类，包含了学生的姓名、学号、性别、班级和成绩等属性。在 main 方法中，创建了一个名为 stu 的 Student 对象，并为其属性赋值，最后输出了学生的信息。

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace WinFormsApp16 { public class student { private int stuno; private string stuname; private int stuage; private string stusex; private string stuspeciality; public student(int myno ,string myname, int myage ,string mysex,string myspecility) { this.Stuno = myno; this.Stuname = myname; this.Stuage = myage; this.Stusex = mysex; this.Stuspeciality = myspecility; } public int Stuno { get => stuno; } public string Stuname { get => stuname; } public string Stusex { get => stusex; } public string Stuspeciality { get => stuspeciality; set => stuspeciality = value; } public int Stuage { get => stuage; set => stuage = value; } } }把这段代码优化成输入信息后再只读

这段代码是 C# 语言的代码，可以通过在 Windows 系统上安装 Visual Studio 编辑器进行修改和运行。

以下是将该代码优化为输入信息后再只读的代码示例：

using System;
using System.Windows.Forms;

namespace WinFormsApp
{
    public partial class Form1 : Form
    {
        private int stuno;
        private string stuname;
        private int stuage;
        private string stusex;
        private string stuspeciality;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnSubmit_Click(object sender, EventArgs e)
        {
            stuno = int.Parse(txtStuno.Text);
            stuname = txtStuname.Text;
            stuage = int.Parse(txtStuage.Text);
            stusex = txtStusex.Text;
            stuspeciality = txtStuspeciality.Text;

            // 显示信息
            txtInfo.Text = $"学号：{stuno}\r\n姓名：{stuname}\r\n年龄：{stuage}\r\n性别：{stusex}\r\n专业：{stuspeciality}";

            // 设置文本框只读
            txtStuno.ReadOnly = true;
            txtStuname.ReadOnly = true;
            txtStuage.ReadOnly = true;
            txtStusex.ReadOnly = true;
            txtStuspeciality.ReadOnly = true;
        }
    }
}

这段代码实现了一个简单的 Windows 窗体应用程序，包含了一个输入学生信息的表单，用户在填写完信息后，点击提交按钮，会将学生信息显示在一个文本框中，并将输入框设置为只读状态，不允许再次编辑。
