3.4 Else If Statements

Else If Statements: Used when you have multiple conditions that need to be checked sequentially.

Flow of Execution: Each condition is evaluated in the order written. The first true condition’s code runs, and the rest are skipped.

Structure:

  • Start with a single if statement.
  • Follow with as many else if statements as needed.
  • Optionally end with one else to handle any remaining cases. Key Concept: The order of conditions matters. More specific conditions should come before broader ones to ensure accurate results.

  1. If I was 19 what would it print out?
    • “Current age: 19”
    • “You can register to vote.”
    • “You are old enough for a license to drive.”
  2. If I was 13 what would it print out?
    • “Current age: 13”
  3. Create your if statement with one else if condition.
boolean a = true;
boolean b = false;
boolean c = false;

if (!(a ^ b)) {
    System.out.println("d");
} else if (c || b ^ a) {
    System.out.println("e");
} else {
    System.out.println("f");
}
