Boolean Expressions

You can pass a boolean expression to a method.

System.out.println( x > y );
System.out.println( "Hello".equals("Howdy") );

A method can return a boolean.

  • You can use a boolean method call anywhere you could use a boolean expression.
  • if expression.
  • while expression.
  • Middle expression in a for.
private static boolean booleanMethod() {
  System.out.println("Hello from booleanMethod, returning true.");
  return true;
}
//...
  if ( booleanMethod() ) {
    System.out.println("booleanMethod returned true.");
  }
//...
