  • equals

    public boolean equals(Object ext)

    Description copied from class: Object
    Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

    The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

    The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

    Overrides:

    equals in class Object

    Parameters:

    ext - the object to compare this instance with.

    Returns:

    true if the specified object is equal to this Object; false otherwise.

    See Also:

    Object.hashCode()

  • hashCode

    public int hashCode()

    Description copied from class: Object
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

    Note that hash values must not change over time unless information used in equals comparisons also changes.

    See Writing a correct hashCode method if you intend implementing your own hashCode method.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.

    Object.equals(java.lang.Object)
