Write a Java program to perform the following tasks: The program should ask the user for the name of an input file (scores.txt). The input file should contain 10 records. Each record in the input file should consist of a name and score between 0 and 100 (inclusive). Eg: fred 95 The program should open the input file as a text file (if the input file does not exist it should throw an exception) and read the contents line by line. Store each record in an array of a user-defined Score class. The Score class can be kept very simple with 2 instance variables, a default constructor, get and set methods for the instance variables. Now process the array of Score class objects to determine: The average of all scores The largest score The smallest score Now output the above stats and all records to the file output.csv. The first line written to this file should consist of the number of records, the average score, the largest score and the smallest score; these values should be comma separated. Finally, the contents of the array of Score objects should be written to output.csv starting from the second line (the first line being taken by the above stats). The format to output the array contents is the same as the input file, with the exception that the fields should be comma separated instead of
