Switch statement with numbers and array of strings Java example.


public class MainClass {
	public static void main(String[] arg) {
		String[] arrayOfString = { "One", "Two", "Three", "Four" };

		int i = 2;
		switch (i) {
			case 1: {
				System.out.println(arrayOfString[i]);
				break;
			}
			case 2: {
				System.out.println(arrayOfString[i]);
				break;
			}
			case 3: {
				System.out.println(arrayOfString[i]);
				break;
			}
			default: {
				System.out.println("Enter a valid value.");
			}
		} // END of switch
	}

/*
 * Three
 */




Possible:

case 1:
 System.out.println(arrayOfString[i]);
break;

// i love this notation 
case 1:{
 System.out.println(arrayOfString[i]);
}break;

case 1:{
 System.out.println(arrayOfString[i]);
 break;
}
