Question

I am an eighth grader on a mission to create an application in Java that finds the point where two virtual lines meet, given the slope and y-intercept of the two lines. As it stands right now, I have two arrays (both with long values) that store the y values for the given x values (x = 0, 1, 2, etc). Now I need to figure out how to create a for each block (you know, the one with the colon in it) to check if the y value in the first array is equal to its counterpart in the other array. How do I do this?

Answer 1

As you have two arrays, you should probably use a normal loop, and not a for-each loop. Something like:

// assuming both arrays are of the same size
for (int i = 0; i < firstArr.length; ++i) {
    if (firstArr[i] == secondArr[i]) {
        // match found
    }
}
