Java program need help asap!!

Write a Java program that allows a teacher to enter student scores for an assignment. When the program starts, ask the user how many grades they would like to enter. Then, ask the user what the name of the assignment is (i.e. Exam #1, Homework #2, etc). Finally, ask them to enter one score at a time. The user will enter a value between 0 and 100 for each score. Note: You do not need to perform input validation for this problem. After the grades have been entered, print out the average score for the assignment. Then, in a file named "scores.txt", append the name of the assignment, a colon, and the average. For example, if the user entered "Homework #1" for the assignment name and the average score was calculated as 93: Homework #1: 93
