I hope this helps you . Your if-else check in method store2D() is not necessary and too messy. Change it like this:
code :
public void store2D(int num){
    System.out.println("R: " + r);
    System.out.println("C: " + c);
    c_array[r][c++] = num;

help you fix your problem array indexes start from 0, if your array is of length 5, the last elemnt will be accessed at 4th index. in your code
code :
  else if (y == array.length && x == array.length)

    up = array[y - 1][x];//Exception here
    down = array[y][x];
    left = array[y][x - 1];
    right = array[y][x];

 else if (y == array.length-1 && x == array.length-1)

        up = array[y - 1][x];
        down = array[y][x];
        left = array[y][x - 1];
        right = array[y][x];

I hope this helps you . The problem is that you use j twice as counter in nested loops
This is where it goes wrong:
code :
for(int i=0; i < DefensiveOppsArray.length; i++){
    for(int j=0; j < DefensiveOppsArray.length; j++){
        //path for straight down
        for(j=0; j < DefensiveOppsArray.length; j++){ // << here you use j again as counter
            path[j] = TicTacToeArray[i][j];
            DefensiveOppsArray[i][j]=DefensiveOppsArray[i][j] + 1;

may help you . WIDTH and HEIGHT are 0 when you are defining board. Constructor is called after class level variables. For int, the default value is 0.

Hope this helps The problem is in the following line: variables=new int [program[1]+2]; Basically, if what I understood is correct, you've re-initialized the variables array and changed its size to 5. Then, in line 50: variables[(program[1])+2]=inputs[0]; you are trying to access the 5th index of the array when the array is defined by indexes ranging from 0 to 4.
