Java Switch Statement

The Java switch statement is executes one statement from multiple conditions. It is like if-else-if ladder statement.

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;  
}  

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:

Java Switch Statement if fall-through

The java switch statement is fall-through. It means it executes all statement after first match if break statement is not used with switch cases.

Example:

public class SwitchExample2 {
public static void main(String[] args) {
	int number=20;
	switch(number){
	case 10: System.out.println("10");
	case 20: System.out.println("20");
	case 30: System.out.println("30");
	default:System.out.println("Not in 10, 20 or 30");
	}
}
}

Output:

20
30
Not in 10, 20 or 30
