Program 2: Design (pseudocode) and implement (source code) a program (name it IndexOflargest) to find the index of the first largest value in the array. Note that the largest value may appear more than once in the array. The program main method defines a single- dimensional array of size 10 elements and prompts the user to enter 10 integers to initialize the array. The main method then calls method findIndex () that takes a single-dimensional array of integer values and return the index of the first largest value in the array. Notice that array indexing in Java starts with 0. Document your code and properly label the input prompts and the outputs as shown below. Sample run 1: Entered integers: Index of largest value is 5 15 23 -13 12 11 90 25 -17 90 90 Page 1 of 4 Sample run 2: 5678 123 -113 12 5678 -500 2578 17 51 100 Entered integers: Index of largest value is 0 Sample run 3: 125 -3 -13-62 -11 541-125 -117 555 1300 Entered integers: Index of largest value is 9
