Writing a program to print output in java

There are several ways to print an output in java. We can use any of the following methods to print the output.

public class printOutput
{
    public static void main(String args[])
    {
    System.out.println("Hi");
    System.out.print("Hello world!");
    System.out.print("I am in print method");
    }
}

System : It is a class in java.lang, the default package.
out : It is a reference of java.io.PrintStream object and it is also a static member of System class.
println : Prints in a new line.
print : Prints the output.
printf : It works as printf in C/C++.
