Question

You can invoke the println and print methods on which object?

A. the HelloWorld object
B. the String class
C. any PrintStream object
D. any object in Java

Answer 1

The println and print methods can only be invoked on any PrintStream object, such as System.out, which is a static member of the System class.

Step-by-step explanation:

The println and print methods can be invoked on any PrintStream object. In Java, the most commonly used PrintStream object is System.out, which is connected to the console. System.out is a static member of the System class and it is an instance of PrintStream. Therefore, the correct option is C. any PrintStream object. These methods cannot be directly invoked on a HelloWorld object unless it specifically contains them, the String class doesn't contain these methods, and not every object in Java has print or println methods.
