I have a question dealing with Java. Lets say there's a main square array and I want to get every possible 4x4 subarray from it. I've tried to think over this as a nested for loop, and this is what I've come up with. I've thought of the situation as one that depends on the starting point of the subarray as a function of the main array, I'm just having trouble translating it into java.

 

for (int i = 0; i < mainArray.length - 4; i++)

{

for (int j = 0; j < mainArray.length - 4; j++)

{

// Create focal point for new subArray to revolve around, hence creating a new subArray at position [i][j] within the main array.

subArray[0][0] = mainArray[i][j];

// Fill out the rest of each subArray as a 4x4 matrix.

subArray[i][j] = mainArray[i][j];

}

}

Again, this isn't much; please, I don't want to hear how bad I am at coding, I already know; my professor tells me I suck every time I ask the dude for help. How can I make my logic more sound, and how can I translate it to java correctly?
