Question

我是Java的初学者，当我编译下面的代码时，我得到：

Error: Could not find or load main class

这是我的代码：

import java.util.Scanner;

public class Comparision {
    public static void main(string[] args) {
        Scanner j = new Scanner(System.in);
        int a,b;
        System.out.println("enter the value for a");
        a = j.nextInt();
        System.out.println("enter the value for b");
        b = j.nextInt();
        if(a > b)
            System.out.println("a is greater");
        else
            System.out.println("b is greater");
    }
}

Answer 1

import java.util.Scanner;
public class Comparision {
    public static void main(String[] args)
    {
        Scanner j=new Scanner(System.in);
        int a,b;
        System.out.println("enter the value for a");
        a=j.nextInt();
        System.out.println("enter the value for b");
        b=j.nextInt();
        if(a>b)
        {
            System.out.println("a is greater");
        }
        else
            System.out.println("b is greater");
    }
}

字符串不是字符串// java类以大写字母开头

Answer 2

java是一个区分大小写的语言......

这个

public static void main(string[] args)

与此不一样......

public static void main(String[] args)

准确查看参数......

并看到字符串与字符串不一样...

错误，无法找到或加载主类
