Method Detail

### hashCode

    public static int hashCode(int seed,
                               int hashcode)

### hashCode

    public static int hashCode(int seed,
                               boolean b)

### hashCode

    public static int hashCode(int seed,
                               Object obj)

### equals

    public static boolean equals(Object obj1,
                                 Object obj2)

  Check if two objects are equal.

  Parameters:
    `obj1` - first object to compare, may be `null`
    `obj2` - second object to compare, may be `null`
  Returns:
    `true` if the objects are equal or both null

### equals

    public static boolean equals(Object[] a1,
                                 Object[] a2)

  Check if two object arrays are equal.

  - If both parameters are null, return `true`
  - If one parameter is null, return `false`
  - If the array lengths are different, return `false`
  - Compare array elements using .equals(); return `false` if any comparisons fail.
  - Return `true`

  Parameters:
    `a1` - first array to compare, may be `null`
    `a2` - second array to compare, may be `null`
  Returns:
    `true` if the arrays are equal or both null
