Why we use printf instead of Println in Java?
The formatting for printf uses the Formatter class’ formatting syntax. The printf method can be particularly useful when displaying multiple variables in one line which would be tedious using string concatenation: int a = 10; int b = 20; // Tedious string concatenation. System.

Which is an instance of PrintStream in Java?
out: This is an instance of PrintStream type, which is a public and static member field of the System class. println (): As all instances of PrintStream class have a public method println (), hence we can invoke the same on out as well. This is an upgraded version of print (). It prints any argument passed to it and adds a new line to the output.
What does System.out.println ( ) mean?
