You can use it to print data types，It is a subclass of the io stream
(system.out) is a predefined object created to be used with methods such as (.println or .printf) to print out stuff such as ( variables or strings).
You can give it a String or any other value and it will print it to the console. You can add multiple things together with '+' like this: System.out.print("Value of x: " + x);
There is also System.out.println(); which prints something in a new line.
