Switch and Break

Switch-Case in Java



Switch-Case Syntax:


    
switch(expression) {
    
case value1: code block; break;
    
case value2: code block; break;
    
default: code block; break;
    
}



Key Points:

    
The break statement is used to exit the switch block.
    
If no break is used, the next case is executed (fall-through behavior).
    
The default case is optional and runs if no case matches.



Program Example



Input:


public class SwitchExample {
    public static void main(String[] args) {
        int day = 3;
        String dayName;

        // Switch statement with break
        switch (day) {
            case 1:
                dayName = "Sunday";
                break;
            case 2:
                dayName = "Monday";
                break;
            case 3:
                dayName = "Tuesday";
                break;
            case 4:
                dayName = "Wednesday";
                break;
            case 5:
                dayName = "Thursday";
                break;
            case 6:
                dayName = "Friday";
                break;
            case 7:
                dayName = "Saturday";
                break;
            default:
                dayName = "Invalid day";
                break;
        }
        
        System.out.println("Day: " + dayName);
    }
}
