switchdemo1.java

Java面向对象编程(随书配套源代码) 阐述了面向对象编程的思想

package chapter5;
import java.util.Scanner;
public class SwitchDemo1 
{
	public static void main(String[] args) 
	{
		Scanner scanner = new Scanner(System.in);
		System.out.println("现在开始洗衣，请输入一个1－4的整数，" +
				"1－洗普通衣服、2－洗棉大衣、3－洗被单、4－洗西服、其它－停止");
		int in = scanner.nextInt();//获取键盘输入
		switch(in)
		{
		case 1:
			System.out.println("洗普通衣服");
		case 2:
			System.out.println("洗棉大衣");
		case 3:
			System.out.println("洗被单");
		case 4:
			System.out.println("洗西服");
		default:
			System.out.println("洗衣机停止");
		}
