Switch Statement in Java

The switch statement in Java is a decision-making statement that allows a program to execute one block of code from multiple choices. It compares the value of an expression with different case values and executes the matching case block.

The switch statement is used as an alternative to multiple if-else-if statements. It makes programs cleaner, easier to understand, and more organized.

What is Switch Statement in Java?

A switch statement in Java is a control flow statement that selects one block of code from multiple options. The value given to the switch expression is checked against different case values.

When a matching case is found, the code inside that case is executed. If no case matches, the default block is executed.

Syntax of Switch Statement in Java

switch(expression) {
    case value1: 
        // code to execute
        break;
    case value2: 
        // code to execute
        break;
    default;
        // default code
}

How Switch Statement Works in Java?

Example of Switch Statement in Java

public class Main {
    public static voidmain(String[] args) { 
        int day =  2;
        switch (day) {
            case 1: 
           System.out.println("Monday");
                break;
            case 2: 
                System.out.println("Tuesday");
                break;
            default:
                System.out.println("Invalid Day");
        }
         }
        }

Switch Statement with String in Java

Java allows String values in switch statements. The string value is compared with different cases and the matching block is executed.

String language =  "Java";
switch(language) {
    case "Java" :
        System.out.println("Java Programming");
        break;
    default:
        System.out.println("Unknown Language");
}
