What is Switch Statement in java

A switch statement is useful when you need to select one of several alternatives based on the value of an integer, a character, or a String variable. The basic form of the switchstatement is this:

switch (expression)

{

  case constant:

        statements;

        break;

  [ case constant-2:

        statements;

        break;  ] ...

  [ default:

        statements;

        break;  ] ...

}

Example:

package com.opps;

public class SwitchExample {

public static void main(String[] args) {
int lan = 3;
String language;
switch (lan) {
case 1:
language = "C";
break;
case 2:
language = "C++";
break;
case 3:
language = "JAVA";
break;
case 4:
language = "VC++";
break;
case 5:
language = ".NET";
break;
default:
language = "Invalid language";
break;
}
System.out.println(language);

}

}

output:
