Working from Home

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

  1. Read in the user's first and last name on a single line
  2. Read the user's age in as an integer
  3. Read the user's campus ID as a string
  4. Read the user's GPA as a double

Then you will need to display these values in the format:

<Last Name>, <First Name>
<First Name> is <age>
<First Name>’s GPA is <GPA>
<First Name>'s Campus ID is <CampusID>

For example, your output should look like the following: 

Enter Name (First Last): Peter Griffin
Enter age: 42
Enter campus ID: AB01234
Enter GPA: 1.23

Your input:
Griffin, Peter
Peter is 42
Peter’s GPA is 4.00
Peter’s Campus ID is AB01234

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

   public static void main( String[ ] args)
   {


      // Prompt the user to enter his first and last name
      // The names should be on a single line separated by a space
      //  First Last

      // Prompt the user to enter his age (in words)

      // Display the names in the format
      //  Last, First, Age
   }
}
