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,
           java.lang.Object obj)

equals

public static boolean equals(java.lang.Object obj1,
             java.lang.Object obj2)

Check if two objects are equal.

参数:

obj1 - first object to compare, may be null

obj2 - second object to compare, may be null

返回:

true if the objects are equal or both null

equals

public static boolean equals(java.lang.Object[] a1,
             java.lang.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

参数:

a1 - first array to compare, may be null

a2 - second array to compare, may be null

返回:

true if the arrays are equal or both null
