Tutorial 21 : Switch Statement смотреть онлайн

Switch case statement is used when we have number of options (or choices) and we may need to perform a different task for each choice. Java switch statement is like a conditional statement which tests multiple values and gives one output. These multiple values that are tested are called cases. It is like a multi-branch statement.
Syntax:
switch (expression) {
case x :
// code block
break ;
case y :
// code block
break ;
default :
// code block
}
Break statements are used when you want your program-flow to come out of the switch body. Whenever a break statement is encountered in the switch body, the execution flow would directly come out of the switch, ignoring rest of the cases.
A break can save a lot of execution time because it "ignores" the execution of all the rest of the code in the switch block.

The default keyword specifies some code to run if there is no case match . Note that if the default statement is used as the last statement in a switch block , it does not need a break.
PROGRAM :
package switchStatement;

public class Main {

public static void main(String[] args) {
String player = "xyz";

switch (player) {
case "batsmen":
System.out.println(" Batsmen are players who plays with a bat");
break;
case "bowler":
System.out.println("who throws the ball");
break;
case "wicket-keeper":
System.out.println("who keeps the ball behind the wickets");
break;
case "fielder":
System.out.println("who fields in the ground");
break;
default:
System.out.println("no entry present");
break;

}
}
}

OUTPUT
no entry present
