Description

ArrayUtils.isEquals() throws ClassCastException when array1 and array2 are
different dimension.

For example:

boolean[][] array1 = new boolean[][] {

{ true, false }, { true, false }

};
boolean[] array2 = new boolean[]

{ false, true }

;
if( ArrayUtils.isEquals( array1, array2 ) ){ // <== ClassCastException
:

How about the following implementation to avoid the exception?

public static boolean isEquals(final Object array1, final Object array2) {
if( !isSameType( array1, array2 ) ) return false;
return new EqualsBuilder().append(array1, array2).isEquals();
}
