比较3个数大小已经写出,但是若3个数或两个数相等咋办,有什吗好的算法xuexiyixia

import java.util.Scanner;
public class Compare{
public static void main(String args[]){
Scanner sc=new Scanner(System.in);
System.out.println("请输入a的值");
double a=sc.nextDouble();
System.out.println("请输入b的值");
double b=sc.nextDouble();
System.out.println("请输入c的值");
double c=sc.nextDouble();
double t;

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;
}if(a>b){
t=a;
a=b;
b=t;
}
System.out.println(a+"<"+b+"<"+c);
}
}

[走一步-再走一步]

public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入a的值");
        double a=sc.nextDouble();
        System.out.println("请输入b的值");
        double b=sc.nextDouble();
        System.out.println("请输入c的值");
        double c=sc.nextDouble();
        double max = Math.max(Math.max(a,b),c);
        double min = Math.min(Math.min(a,b),c);
        double mid = a+b+c - max - min;
        System.out.println(min+"<"+mid+"<"+max);
    }
