A Math teacher is teaching Math course to a set of classes (each class may have different number of students) and want to check the behavior of his students in a homework report. The teacher gave the classes the same exam and marked their answer and wants to know the class whose students got the highest average. Help the teacher in the required analysis of student's marks by implementing a Java program ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks and then compute the average of each class student's marks. The program has the following specification: • A Method titled averageClassMarks for computing the average (as double) of a class students marks (given to the method as a single-dimensional array) • Another Method titled averageAllclassesMarks for computing the average (as single array of double) of all the classes class student's marks (given to the method as a 2- dimensional array). This method has to repeatedly call the first method averageClassMarks to calculate the average of student's marks in each class. • The program reads from the user the number of classes and then reads the classes student's marks (as integer values) line by line. Each line has the number of students in the class then the student's marks. • The program calls method averageAllClassesMarks to calculate all the average values of marks of all the classes. Again, method averageAllClassesMarks has to repeatedly call the first method averageClassMarks. • Finally, the program then prints all the average values (rounded to 2 decimal points) of all classes student's marks and the highest average mark as well. • The program has to work EXACTLY as given in the following sample run. Sample Run: Enter number of classes: 5 Enter student's marks of al1 the classes line by line such that, each line contains first the number of students in a class followed by the student's marks: 6 50 84 76 94 62 98 5 42 64 97 88 80 6 25 35 86 47 36 75 7 59 74 96 94 82 75 98 4 88 62 56 74 Classes average marks: Class Average 33 .7ר 1 2 74.20 3 50.67 4 82.57 70.00 The highest average is 82.57 and it is for class 4.

The program has to work EXACTLY as given in the following sample run
Transcribed Image Text:A Math teacher is teaching Math course to a set of classes (each class may have different number
of students) and want to check the behavior of his students in a homework report. The teacher
gave the classes the same exam and marked their answer and wants to know the class whose
students got the highest average.
Help the teacher in the required analysis of student's marks by implementing a Java program
ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks
and then compute the average of each class student's marks. The program has the following
specification:
• A Method titled averageClassMarks for computing the average (as double) of a class
students marks (given to the method as a single-dimensional array)
• Another Method titled averageAliclassesMarks for computing the average (as
single array of double) of all the classes class student's marks (given to the method as a 2-
dimensional array). This method has to repeatedly call the first method
averageClassMarks to calculate the average of student's marks in each class.
• The program reads from the user the number of classes and then reads the classes
student's marks (as integer values) line by line. Each line has the number of students in
the class then the student's marks.
• The program calls method averageAllClassesMarks to calculate all the average
values of marks of all the classes. Again, method averageAllClassesMarks has to
repeatedly call the first method averageClassMarks.
Finally, the program then prints all the average values (rounded to 2 decimal points) of all
classes student's marks and the highest average mark as well.
• The program has to work EXACTLY as given in the following sample run.
Sample Run:
Enter number of classes: 5
Enter student's marks of all the classes line by line such that, each
line contains first the number of students in a class followed by the
student's marks:
6 50 84 76 94 62 98
5 42 64 97 88 80
6 25 35 86 47 36 75
7 59 74 96 94 82 75 98
4 88 62 56 74
Classes average marks:
Class Average
1.
77.33
2
74.20
3
50.67
82.57
70.00
The highest average is 82.57 and it is for class 4.
