Question

请为这段简单的java代码编写junit测试，我想借此理解一下junit

import java.util.*;
public class Compare{
public static void main(String[] arg){
int a,b,c,t;
Scanner in = new Scanner(System.in);
System.out.printf("Please enter three numbers:");
a = in.nextInt();
b = in.nextInt();
c = in.nextInt();
if(a>b){
t=a;a=b;b=t;
}
if(b>c){
t=b;b=c;c=t;
}
if(a>c){
t=a;a=c;c=t;
}
System.out.print(a+" ");
System.out.print(b+" ");
System.out.print(c+" ");
}
}

这个没什么好写JUnit的 ，因为你连模块都没有 ，何来单元测试之说
