The if statement

The if statement allows you to execute a certain block of code only if a certain condition is true. It is defined as this template:

if ( condition ) {
      body
}

where

• condition is a boolean expression;
• body is zero or more statements;
• The if statement executes the code in body if and only if condition evaluates to true.

The following code prints a warning message if a player's health goes below a certain threshold.

if (health < healthWarningThreshold) {
   System.out.println("Careful -- your health is dangerously low.");
}
