import java.util.Scanner;

public class Example3_2{
    public static void main(String args[]){
        System.out.println("Please input three integers:");
        Scanner sc = new  Scanner(System.in);
       int[] a= new int[3];
       int t=0;
       for(int i=0;i<3;i++){
           a[i] = sc.nextInt();
       }
        if(a[1]<a[0]){
            t = a[0];
            a[0] = a[1];
            a[1]= t;
        }
        if(a[2]<a[0]){
            t = a[0];
            a[0] = a[2];
            a[2]= t;
        }
        if(a[2]<a[1]){
            t = a[1];
            a[1] = a[2];
            a[2]= t;
        }
        System.out.println("The order from small integer to big integer is: "+a[0]+","+a[1]+","+a[2]);
    }
}

结果
