Switch

Switch statements in Java provide a cleaner way to handle multiple conditions compared to long if-else-if chains, especially when comparing a single variable against multiple values.

Basic Syntax

switch (expression) {
  case value1:
    // Code to execute if expression equals value1
    break;
  case value2:
    // Code to execute if expression equals value2
    break;
  // More cases...
  default:
    // Code to execute if expression doesn't match any case
}

Example

int day = 3;
String dayName;

switch (day) {
  case 1:
    dayName = "Monday";
    break;
  case 2:
    dayName = "Tuesday";
    break;
  default:
    dayName = "Invalid day";
}

System.out.println(dayName);  // Output: Wednesday
