public boolean firstElementsEqual(int[] a, int[] b)

Given two arrays - a and b - both of whose lengths are at least 1,
return true if their first elements are the same.

public boolean firstElementsEqual(int[] a, int[] b) {
  boolean equals = false;
  if (a[0] == b[0]) {
    equals = true;
  }
  return equals;
}
