【王道JAVA】【程序 34 三個數排序】

題目：輸入 3 個數 a,b,c，按大小順序輸出。

import java.util.Scanner;

public class WangDao {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		System.out.print("Input a: ");
		int a = scan.nextInt();
		System.out.print("Input b: ");
		int b = scan.nextInt();
		System.out.print("Input c: ");
		int c = scan.nextInt();
		
		if (a > b) {
			int temp = a;
			a = b;
			b = temp;
		}
		if (a > c) {
			int temp = a;
			a = c;
			c = temp;
		}
		if (b > c) {
			int temp = b;
			b = c;
			c = temp;
		}
		System.out.println("a--b--c: " + a + "--" + b + "--" + c);
	}
