Switch statement
The java switch statement executes one statement from multiple conditions.
It is like if-else-if ladder statement because in both of them different conditions are to be checked and from the behalf of it,statement would be executed.
Syntax:
switch(expression){
case value1: //code to be executed;
break; //optional
case value2: //code to be executed;
break; //optional
......
default:
code to be executed if all cases are not matched;
}
fig: Switch statement
Example:
public class SwitchExample {
public static void main(String[] args) {
int number=20;
switch(number){
case 10: System.out.println("10");
break;
case 20: System.out.println("20");
break;
case 30: System.out.println("30");
break;
default:System.out.println("Not in 10, 20 or 30");
}
}
}
Output: 20
If you execute switch statement without break, then it executes all statements after first match.
