JavaElse

The else Statement

Theelse statement lets you run a block of code when the condition in theif statement isfalse.

if (condition) {  // block of code to be executed if the condition is true} else {  // block of code to be executed if the condition is false}

Think of it like real life:If it rains, bring an umbrella.Otherwise (else), go outside without one:

boolean isRaining = false;if (isRaining) {  System.out.println("Bring an umbrella!");} else {  System.out.println("No rain today, no need for an umbrella!");}

SinceisRaining is false, the condition inside theif statement is not met. That means theif block is skipped, and theelse block runs instead, printing "No rain today, no need for an umbrella!".

Another Example

This example says good day or good evening depending on the time:

int time = 20;if (time < 18) {  System.out.println("Good day.");} else {  System.out.println("Good evening.");}// Outputs "Good evening."

Example explained

In the example above, time (20) is greater than 18, so the condition isfalse. Because of this, we move on to theelse condition and print to the screen "Good evening". If the time was less than 18, the program would print "Good day".
