Thank you for helping with this question

1. Create a Java program named student1.java that will use arrays to store student names and grades assume each student has a student id that directly indexes a storage slot in a set of parallel arrays. One of the arrays should be named stu_name[] The other stu_grade[] Make room for 100 students. Your program should prompt the user to input a student id, name, and grade. Let the user continue to enter grades using a sentinel value of -1 for the id to indicate that the input is complete. Once input is complete the program should call the following display() and classavg() methods. Then prompt the user for a student id and use the findid() method below to find and display the students name and grade associated with the id.
   1. Write a method named display() that will display back the list of students.
   2. Write a method named classavg() that will calculate the class average and display the result.
   3. Write a method named findid() that will find a student based on the id and display the students name and grade. Add a comment to the end of your code file with the following: What is the O() of the display() and classavg() methods. What is the O() of the findid() method.
