Switch---case的条件案例

Switch---case

1. switch(判断条件){-----case}：

    import java.util.Scanner;
    class JavaVer14{
    	public static void main(String[] agre)
    	{
    		Scanner sc = new Scanner(System.in);
    		System.out.print("请输入星期：");
    		int week = sc.nextInt();
    		switch(week)//注意格式
    		
    		{
    			default:
    			
    				System.out.print("输入错误");
    				break;//如果放在前面不加break；则无法阻止条件的穿透
    			case 1:
    			
    				System.out.print("星期一：");
    			        break;
    			case 2:
    			
    				System.out.print("星期二：");
    			        break;
    			case 3:
    			
    				System.out.print("星期三：");
    			        break;
    			case 4:
    			
    				System.out.print("星期四：");
    			        break;
    			case 5:
    			
    				System.out.print("星期五：");
    			        break;
    			case 6:
    			
    				System.out.print("星期六：");
    			        break;
    			case 7:
    			
    				System.out.print("星期日：");
    			        break;
    			
    			
    		}
    	}
    }
