Computer Science I Lab 070-Grades, revisited Lab Goal: This lab was designed to teach you how to use an array. Lab Description : highest grades. Build two arrays with student names and grades. Find out who has the lowest and Sample Data : joebob,73 greg,20 mary, 100 calvin,99 joseph,80 jose,75 marta,92 franz,56 Programs needed: Sample Output : lab07c.java lab07c.dat GradeBook.java rinnavoro The student list is: 1 joebob 73 2. greg 20 3. mary 100 4. calvin 99 5. joseph 80 6. jose 75 7 marta 92 8 franz 56 When you get the results shown, create a new dat file with your own data. Check your results. (Name your new file 'lab07c2.dat') Average = 74.375 greg has the lowest grade. mary has the highest grade
