Using Console

In this program, you will use the Scanner class and System.out object to perform console I/O. In the main method, you will:

• Read two integers
• Read the user's name
• Read a double
• Display the following: the user's name, the sum of the two integers, and the sum multiplied by the double.

You can copy the following class skeleton into a new class file to start with.

// Import the Scanner class from the Java library here.

public class Lab2
{
   // Declare a Scanner reference variable and create
   // a Scanner object here.
   // Note that this reference will have class scope.

   // Define and implement an add( ) method here.
   // add( ) returns the sum of two integers.

   // Define and implement a product( ) method here.
   // product( ) returns the product of two doubles.

   public static void main( String[ ] args)
   {
      // Prompt for and read in two integers.

      // Prompt for and read in the user's name.
      // Note that the user's name may contain spaces.

      // Prompt for and read in a double.

      // Display the user's name with an appropriate label.

      // Call the add( ) helper method here.
      // Display its return value with an appropriate label.

      // Call the product( ) helper method here.
      // Display its return value with an appropriate label.
   }
}
