Java comparison array

I have two arrays of unknown types... One way to check elements is the same:

public static boolean equals(Object a,Object b) {
  if (a instanceof int[])
    return Arrays.equals((int[]) a,(int[])b);
  if (a instanceof double[]){
    ////etc
}

I want to do this without all the instanceof checks

Solution

ArrayUtils. Isequals () does this from Apache Commons It also handles multidimensional arrays
