3.3 If Else Statements
Purpose of Else Statements
Else statements: Handles what happens when the if condition is false. Structure of If-Else:
- If statement with a condition.
- Else statement without a condition.
- Both parts have code blocks surrounded by {}.
don’t forget the brackets
if (x > 10) {
console.log("x is greater than 10");
console.log("This code when the condition is true");
} else {
console.log("x is 10 or less");
console.log("This code runs when the condition is false");
}
Without brackets:
if (x > 10)
console.log("x is greater than 10");
console.log("this code will always run");
| console.log("x is greater than 10");
illegal character: '\u00a0'
| console.log("x is greater than 10");
illegal character: '\u00a0'
| console.log("x is greater than 10");
illegal character: '\u00a0'
| console.log("x is greater than 10");
illegal character: '\u00a0'
| console.log("This code when the condition is true");
illegal character: '\u00a0'
| console.log("This code when the condition is true");
illegal character: '\u00a0'
| console.log("This code when the condition is true");
illegal character: '\u00a0'
| console.log("This code when the condition is true");
illegal character: '\u00a0'
| console.log("x is 10 or less");
illegal character: '\u00a0'
| console.log("x is 10 or less");
illegal character: '\u00a0'
| console.log("x is 10 or less");
illegal character: '\u00a0'
| console.log("x is 10 or less");
illegal character: '\u00a0'
| console.log("This code runs when the condition is false");
illegal character: '\u00a0'
| console.log("This code runs when the condition is false");
illegal character: '\u00a0'
| console.log("This code runs when the condition is false");
illegal character: '\u00a0'
| console.log("This code runs when the condition is false");
illegal character: '\u00a0'

- “You are not old enough for a license yet”
- Write your own if else statement
boolean a = true;
boolean b = false;
boolean c = false;
if (a ^ b) {
System.out.println("d");
} else {
System.out.println("e");
}
d
