Question

What is wrong with this sequential search? m_t3[] is an integer array with some combination of the numbers 0, 1, and 4 filling it. (The size of the array is 9). NetBeans giving me an error message, incomparable types: int[] and int. The examples I’ve seen for this type of search look like this though.

int key = 0;
boolean cat = false;
for (int i = 0; i < m_t3.length; i++) {
    if (m_t3[i] == key) {
        cat = true;
        break;
    }
}

Answer 1

The only line that could be problematic in your code is

if (m_t3[i] == key)

It seems that your m_t3 is as an array of arrays and not a simple array. Double-check your declaration.
