Java Getting User Inputs

In This Example We Are Trying To Get User Inputs and Print It.
Open Text File & Save As SayHello.Create The Class and Main Method Inside It.Inside The Method Print A Text Line Asking User To Input The Name.

class SayHello {
   public static void main(String args[]){
      System.out.print("Enter The Name : ");
   }
}

To Get The User Inputs We Need A Scanner Object.But By Default Scanner Class Is Not Available Us To Create A Scanner Object.You Need To Import The Scanner Class First.After That You Can Use The Scanner Class.Create A String Variable To Save The Name and Create A Scanner Object To Get The User Inputs. 

import java.util.Scanner;

class SayHello {

   public static void main(String args[]){
      Scanner MyScanner = new Scanner(System.in);
      String Name;
      System.out.print("Enter The Name : ");
   }
}

Now We Need Is Get The User Input and Print It Again In The Command Prompt.Use Scanner.in Method To Get The User Inputs.Complete The Coding.

import java.util.Scanner;

class SayHello {

   public static void main(String args[]){
      Scanner MyScanner = new Scanner(System.in);
      String Name;
      System.out.print("Enter The Name : ");
      Name = MyScanner.nextLine();
      System.out.print("Hello ");
      System.out.print(Name);
   }
}

Now Run The Program.It Will First Print "Enter The Name : " and Wait For User Input.Type The Name and Press Enter Button To See The Output.You Will Get Following Outputs At The End.

Enter The Name : Nifal
Hello Nifal
