public class ST_SWITCH {

	public static void main(String[] args) {
		
		System.out.println("Start");

		//
		System.out.println("------------------------");
		
		int i = 3;
		
		switch(i)
		{
			case 1:
				System.out.println("i -> One");
				break;
			
			case 2:
				System.out.println("i -> Two");
				break;

			case 3:
				System.out.println("i -> Three");
				break;
			
			default:
			System.out.println("error");
			break;
			
		}
		
		
		//breakなし！！
		switch(i)
		{
			case 5:
				System.out.println("i > 4");
				
			case 4:
				System.out.println("i > 3");
	
			case 3:
				System.out.println("i > 2");

			case 2:
				System.out.println("i > 1");
				
			case 1:
				System.out.println("i > 0");
				break;
	
			default:
				System.out.println("error");
				break;
				
		}
		
		
		
		//
		System.out.println("------------------------");
		
		System.out.println("End");
		
	}
}
