intorduction to java programming 10th edition

question 1) write a program that prompts the user to enter the number of students, the students names, and their scores, and prints student names in decreasing order of their scores

question 2)write a program that generates 100 random integers between 0 and 9 and displays the count for each number. (hint: use an array of ten integers, says count, to store the counts for the number of 0's,1s.....,9s

question 3)the two dimensional arrays m1 and m2 are identical if they have the same contents. Write a method that returns true if m1 and m2 are identical using the follwing header: public static boolean equals (int[][] m1, int[][] m2)

write a test program that prompts the user to enter two 3x3 arrays of integers and displays whether the two are identical. Here are the sample returns

Enter list1: 51 25 22 6 1 4 24 54 6

Enter list2: 51 22 25 6 1 4 24 54 6

the two arrays are identical

Enter list1: 51 5 22 6 1 4 24 54 6

Enter list2: 51 22 25 6 1 4 24 54 6

The two arrays are not identical

question 4) design a class named LinearEquation for a 2x2 system of linear equations:

the class contains:

-private data fields a,b,cd,e and f.

-a constructor with arguments for a,b,c,d,e and f.

-six getter methods for a,b,c,d,e and f

- a method named isSolvable() that returns true if ad - bc is not 0.

-Mehtods getX() and getY() that return the solution for the equation

draw the UML diagram for the class and then implement the class. Write a test program that prompts the user to enter a,b,c,d,e and f and displays the result. If ad-bc is 0, report that "The equation has no solution."

Thanks! all 4 questions are there and i need help on ALL of them
