Explain System.out.println in Java

In Java, System.out.println is a method used to display text on the console or terminal. It belongs to the java.lang package and is a member of the System class.

The System.out is an instance of the PrintStream class, which provides methods for writing various data types to a stream, including strings, integers, and characters. The println method is used to print a string to the console and add a newline character at the end.

Here is an example:

System.out.println("Hello, World!");

This will output the following to the console:

Hello, World!

The System.out.println method is commonly used for debugging and displaying messages to the user in console-based Java applications.
