switch-as statement

case judges the condition; if true, enter it, and then jump out until the break statement is encountered

public class SwitchDemo02
{
    
    
	public static void main(String[] args)
	{
    
    
		int week = 3;
	
		switch(week){
    
    
			case 0:
				System.out.println("Sunday");
				break;
			case 1:
				System.out.println("Monday");
				break;
			default:
				System.out.println("data error!");
				break;
			case 2:
				System.out.println("Tuesday");
				break;
			case 3:
				System.out.println("Wednesday");
//				break;
			case 4:
				System.out.println("Thursday");
//				break;
			case 5:
				System.out.println("Friday");
				break;
			case 6:
				System.out.println("Saturday");
				break;
		}
