  1. There are two arrays of length 100 each. Each of these has initially n (n<100) elements. First array contains names and the second array contains numbers such that ith name in array1 corresponds to ith number in array2.  Write a program which asks the user to enter a name prints its corresponding number in array2. And if that name is not present in Array1, ask the user to input a number and then if the size permits, add the name and number to array1 and array2 respectively at the end and update the size(n) of list.

  1. class Number{
    int num;
    public Number(int num){
    this.num = num;
    }

    abstract class Getter{
    public abstract void getNum();
    public abstract void getSqr();
    public void getAll(){
    getNum();
    getSqr();
    }
    }

    }

    class MyClass extends Number.Getter{
    }

    (a) Complete the code for MyClass in which you've to pass a integer to Number class and call getAll() method from MyClass' constructor to get desired results.

    (b) Create an arraylist of MyClass and print all results by passing 1-10 in 10 arraylist object.


    please provide the code.
