The brackets following the if statement delimit a block of code to be executed when the expression in the if statement is true.
A break statement ends the execution of the code within the block. That means the println statement following the break can never be reached.
Without the brackets, the default block of code controlled by the if statement is the single break statement following the if statement.
That leaves the println statement outside of the if statement's control. It will be executed when the if statement's expression is false.
