User Input :- User input is data that is entered by the user of a Java program. This data can be used by the program to perform tasks or to display information to the user.

Another way to get user input is to use the System.in object. The System.in object represents the standard input stream, which is the keyboard by default.

How to display user output in Java?

There are several ways to display user output in Java. One way is to use the System.out object. The System.out object represents the standard output stream, which is the console by default.

Another way to display user output is to use the print() and println() methods. The print() method displays the specified text without adding a newline character. The println() method displays the specified text and adds a newline character.

{

    public static void main(String[] args)

   {

        Scanner ob= new Scanner(System.in); //System.in is a standard input stream.

        System.out.print(“Enter a Value : “);

         int n= ob.nextInt(); //reads Value by given the value of user.

          System.out.printnl(“Users given value is : “,+n); // display the the  output users given values like hare (n).
