将3个整数按从小到大的顺序输出

import java.util.Scanner;

public class MaxMin {

	public MaxMin(int x, int y, int z){
		int t;
		int ThreeNum[] = {x, y, z};
		
		for(int i = 0; i < ThreeNum.length - 1; i++)
		{
			for(int j = 0; j < ThreeNum.length - 1 - i; j++)
			{
				if(ThreeNum[j] > ThreeNum[j + 1])
				{
					t = ThreeNum[j];
					ThreeNum[j] = ThreeNum[j+1];
					ThreeNum[j+1] = t;
				}
			}
		}
		
		System.out.println("The oder of this three numbers:");
		for(int i = 0; i < ThreeNum.length; i++)
			System.out.print(ThreeNum[i] + " ");
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		int x, y, z;
		
		Scanner scan = new Scanner(System.in);
		
		System.out.println("Input three number:");
		x = scan.nextInt();
		y = scan.nextInt();
		z = scan.nextInt();
		
		new MaxMin(x, y, z);
	}

}

首先将输入进来的3个数存入数组里，然后通过冒泡排序来进行排序，最后再输出3个数的顺序。

结果：
