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.
- If I was 19 what would it print out?
- If I was 13 what would it print out?
-
Create your if statement with one else if condition.
- It would print “You can register to vote.” and “You are old enough for a license to drive.”
- It would not print out anything since none of the conditions would be met
- Here is my if statement:
int name = "Aadit"; if (name.equals("Shuban")) { System.out.println("Exile this man to Ohio!"); } else if (name.equals("Aadit")) { System.out.println("Ah, we've met a worthy person."); }
