Question

• Using jGRASP, write a Java program named LastnameFirstname10.java, using your last name and your first name, that does the following:
  • Create two arrays that will hold related information.
    • You can choose any information to store, but here are some examples:
      • an array that holds a person's name and an array that hold's their phone number
      • an array that holds a pet's name and an array that holds what type of animal that pet is
      • an array that holds a student's name and an array that holds what their grade is.
  • Allow a user to fill in the information for the array. Use a loop.
    • Note: Limit the size of your array. Make it at least size 3, but no larger than 10.
  • Print out the contents of both arrays so that the information in the different arrays are presented in a coherent manner.
    • Examples:
      • Nikki's phone number is: 455-0123
        Ed's phone number is: 455-0987
        Blanca's phone number is: 455-3456
      • Snoopy is a pet dog
        Garfield is a pet cat
        Pudge is a pet fish
      • William : B
        Mike : C
        Pete : A
  • Use loops to print out the contents of the arrays.
  • Note: You can make your arrays hold whatever information you want. You don't need to follow the examples. Be creative as you wish! :)
• Your program MUST:
  • Actively use in-line comments stating what each section of code does.
  • Use try/catch if, and only if, necessary.
  • Begin storing data in the first box of the array - not the second.
• Your program must conform to the Java coding standards

        /*declare two arrays*/

        String[] names=new String[5];

        String[] grades=new String[5];

        /*read data into arrays*/

        System.out.println("Enter student names and their grades:");

        for(int i=0;i<5;i++)

        {

            /*read name from user and store it in names array*/

            System.out.print("Name: ");

            names[i]=read.nextLine();

            /*read grade from user and store it in grades array*/

            System.out.print("Grade: ");

        }

        System.out.println("Name\tGrade");

        for(int i=0;i<5;i++)

            System.out.println(names[i]+":  "+grades[i]);

    }
