5.1.2. Missing else blocks

What happens if you don’t define the else statement for an if construct? It’s acceptable to define one course of action for an if construct as follows (omitting the else part):

boolean testValue = false; if (testValue == true) System.out.println("value is true");

But you can’t define the else part for an if construct, skipping the if code block. The following code won’t compile:

boolean testValue = false; if (testValue == true) {} else System.out.println("value is false");
