Switch Case in Java - Syntax and Examples

Switch Statement

Selects one of many code blocks to be executed.

int day = 4;
switch (day) {
  case 1:
    System.out.println("Monday");
    break;
  case 2:
    System.out.println("Tuesday");
    break;
  case 3:
    System.out.println("Wednesday");
    break;
  case 4:
    System.out.println("Thursday");
    break;
  default:
    System.out.println("Weekend");
}

Important Points

• The break keyword stops execution. If omitted, it "falls through" to the next case.
• The default case runs if no match is found.
• Supports primitives (byte, short, int, char), Enums, and String.
