方法详细资料

equals

public final boolean equals(Object obj)

Compares two Subset objects for equality. This method returns true if and only if this and the argument refer to the same object; since this method is final, this guarantee holds for all subclasses.

覆盖:

equals 在类中 Object

参数:

obj - the reference object with which to compare.

返回:

true if this object is the same as the obj argument; false otherwise.

Object.hashCode(), HashMap

hashCode

public final int hashCode()

Returns the standard hash code as defined by the Object#hashCode method. This method is final in order to ensure that the equals and hashCode methods will be consistent in all subclasses.

覆盖:

hashCode 在类中 Object

返回:

a hash code value for this object.

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public final String toString()

Returns the name of this subset.

覆盖:

toString 在类中 Object

返回:

a string representation of the object.
