Help I am new

Question

Hello I am new and need to do the following I have part 1 done, but I am having trouble with part 2.
Part 1
Create a Class called SquareGenerator, and declare a two dimensional array as a class variable. In your main method create two instances of SquareGenerator, construct unique instances of SquareGenerator by passing in a random size from 1 to 10 into the Constructor of Square Generator. Do not store the length in a class variable. Create a method called FillSquare in class SquareGenerator. FillSquare should fill each cell in your random sized array with a random number from 1 to 1000. Another method called write should be created and output the random square to the screen. I want to see both squares in row and column format, one below the other.
For example (letters represent random numbers):
Square 1:
A B C
D E F
G H I
Square 2:
W X
Y Z
Order of events
Create each Square
Fill each cell in array with random number
Output square to screen
Part 2.
Once you have the above working correctly I would like you to perform operations on the array. You will need to write methods in SquareGenerator to do the following:
Return the sum of each cell in the square (notice I said RETURN, meaning your method cannot be of type void)
Return the Sum of the first row
Return the Sum of the last column
Return the Sum of the diagonal
Now in main I want you to use if statements to compare the results of the squares and tell me which is greater for each of the above values, ie if square1 sum is greater then square2, the output should be:
The sum of each cell for square one is X
The sum of each cell for square two is Y
Square 1 cell sum is greater then Square 2
Note X and Y can be any number. If the opposite were true the first two lines would remain the same but the output would be:
Square 2 cell sum is greater then Square 2
What have I left out? The off chance that they were equal, so I guess you will have to use and if, else if, else statement...
The above method will need to be applied to each of four calculations I requested: total cell sum, sum of first row, sum of last column, sum of diagonal.
Here is my code. (sorry it is bad)
class SquareGenerator
int array[][];
SquareGenerator ()
int num= (int) (10 * Math.random());

System.out.print(array[i][j] + " ");
System.out.println();

int sum =0;
for (int i = 0; i < array.length; i++)

System.out.println("Square two Sum is greater than square 1 sum");

else
System.out.println("They are equal");

int sum6 = square1.SumColumn();

int sum7 = square1.DiagSum();
int sum8 = square2.DiagSum();

Please help
Thank You

Answer 1

Ok, Lenny.
Firstly tell you tutor that method names are starting with small letters by convention.
Read the assignment better sum of last[bold] column was asked. The compare method must either be called from a squareGenerator object or it must be defined as static. class SquareGenerator {
     int array[][];
     SquareGenerator() {
          int num = (int) (10 * Math.random());
          array = new int[num][num];
     void fillSquare() {
          for (int i = 0; i < array.length; i++) {
               for (int j = 0; j < array.length; j++) {
                    array[i][j] = (int) (1000 * Math.random());
     void write() {
          for (int i = 0; i < array.length; i++) {
               for (int j = 0; j < array[i].length; j++) {
                    String s =(array[i][j] + " ");
                    while(s.length()<4)
                         s=" " +s;
                    System.out.print(s);
               System.out.println();
          System.out.println();
     int sumSquare() {
          int sum = 0;
               for (int i = 0; i < array.length; i++) {
                    for (int j = 0; j < array.length; j++) {
                         sum = sum + array[i][j];
          return sum;
     int sumRow() {
          int sum = 0;
               for (int j = 0; j < array.length; j++) {
                    sum = sum + array[0][j];
          return sum;
     int sumColumn() {
          int sum = 0;
               for (int i = 0; i < array.length; i++) {
                    sum = sum + array[i][array.length-1]; // last Col
          return sum;
     int diagSum() {
          int sum = 0;
               for (int i = 0; i < array.length; i++) {     
                         sum = sum + array[i][i];
               return sum;
     void compareSum(int sum1, int sum2, String s) { // non static
               System.out.println("The sum of "+ s +" for square one is: " + sum1);
               System.out.println("The sum of "+ s +" for square two is: " + sum2);
          if (sum1 > sum2) {
               System.out.println("Square one Sum is greater than square 2 sum\n");
          } else if (sum1 < sum2) {
               System.out.println("Square two Sum is greater than square 1 sum\n");
          } else {
               System.out.println("They are equal\n");
     public static void main(String args[]) {
          SquareGenerator square1;
          square1 = new SquareGenerator();
          SquareGenerator square2;
          square2 = new SquareGenerator();
          square1.fillSquare();
          square1.write();
          square2.fillSquare();
          square2.write();
          square1.compareSum(square1.sumSquare(), square2.sumSquare(),"each cell"); //non static call
          square1.compareSum(square1.sumRow(), square2.sumRow(),"first row");
          square1.compareSum(square1.sumColumn(), square2.sumColumn(),"last col");
          square1.compareSum(square1.diagSum(), square2.diagSum(),"diagonals");
