Describe the components (objects and classes) that are used in the statement System.out.println().

Question

What will be an ideal response?

Answer 1

Within the statement System.out.println("First Java application");, the method to which you are passing "First Java application" is named println(). The Java methods println() and print() both produce output. With println(), after the output is displayed, the insertion point moves to the following line so that subsequent output appears on a new line. With print(), however, the insertion point does not advance to a new line, so subsequent output appears at the end of the current line.Within the statement System.out.println("First Java application");, out is an object that is a property of the System class that refers to the standard output device for a system, normally the monitor. The out object itself is an instance of the PrintStream class, which contains several methods, including println().Within the statement System.out.println("First Java application");, System is a class. Therefore, System defines attributes for System objects, just as the Dog class defines the attributes for Dog objects. One of the System attributes is out. The dots (periods) in System.out.println() are used to separate the names of the components in the statement.
