boolean equals (Object o)

指示其他某个对象是否“等于”这一个。

equals方法在非空对象引用上实现等价关系:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null 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 non-null 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 non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

Objectequals方法实现了对象上最可能的等价关系; 也就是说,对于任何非空参考值xy ,当且仅当xy引用同一对象( x == y的值为true )时,此方法返回true

请注意,无论何时重写此方法,通常都必须覆盖 hashCode方法,以便维护 hashCode方法的常规协定,该 hashCode声明相等对象必须具有相同的哈希代码。

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

Hooray!
