Please would you help answer the below question by following these instructions. Thank you

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.
2. 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.
3. Once input is complete the program should call the following display() and classavg() methods.
4. 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.
5. 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.

1. Create a program named student2.java. This program will differ from program 1 in that it will use three arrays to store student id, names, and grades. Store the data in the array in sequence as it is entered. Make room for 100 students.
2. Otherwise, this program should do all of the same tasks that are required in program 1.
3. 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. Compare the big O() values between the first program and the second. Write a paragraph describing the pros and cons of these two different implementations of the student data storage.
