Operators and Variables in JavaThe purpose of this assessment is to identify the usage of a variable that allows you to store a sequence of similar values and provide quick access to each of these values individually.Suppose you have to write a program for storing the grades of 100 students of a college. Which one of the following code fragments will enable you to declare variables to store 100 different values?int[] a = new[100];for (int i=0; i<=100; i++)a[i]=i + 1;int a[100]; int[] a = new int[100];for (int i=0; i<100; i++)a[i]=i + 1; int a1, a2, a3, a4, a5 .... A100;a1 = 1;a2=2;a3 = 3;a4 =4;a5 = 5;.........A100 =100;Support your selection with a rationale. Discuss the errors or shortcomings in the incorrect code examples and identify ways to fix them.
