Question

Given:

int[] studID = {314,123,896,576};

String[] name = {"John Doe", "Mary Jane", "Bill Gates", "Peter Pan"};

String[] major = {"Math","English","History","Engineering"};

int[] level = {4,3,1,2};

Create a program that accecpt a student ID as an imput. Use the entered ID number to search for and return the students info. Provide a list of valid student ID numbers as part of the user prompt. Observe standard coding practices. Save the file as ParallelArrayDemo.java

Output format:

Student Info

id:

name:

major:

level:
