Class Object

    java.lang.Object

    public class Object

Class `Object` is the root of the Java Card platform class hierarchy. Every class has `Object` as a superclass. All objects, including arrays, implement the methods of this class.

This Java Card platform class's functionality is a strict subset of the definition in the JavaTM 2 Platform Standard Edition (J2SETM) API Specification.

Method Detail

### equals

    public boolean equals(Object obj)

  Compares two Objects for equality.

  The `equals` method implements an equivalence relation:

  - It is reflexive: for any reference value `x`, `x.equals(x)` should return `true`.
  - It is symmetric: for any reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
  - It is transitive: for any reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
  - It is consistent: for any reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`.
  - For any reference value `x`, `x.equals(null)` should return `false`.

  The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x==y` has the value `true`).

  Parameters:
    `obj` - the reference object with which to compare.
  Returns:
    `true` if this object is the same as the obj argument; `false` otherwise.
