equals

boolean equals (Object other)

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.

equals类的方法Object实现对象上最可能的等价关系; 也就是说，对于任何非空参考值x和y ，当且仅当x和y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，通常都必须重写 hashCode方法，以便维护 hashCode方法的常规协定，该方法声明相等对象必须具有相同的哈希码。

getBasestationId

int getBasestationId ()

getLatitude

int getLatitude ()

getLongitude

int getLongitude ()

getNetworkId

int getNetworkId ()

getSystemId

int getSystemId ()

hashCode

int hashCode ()

返回对象的哈希码值。 为了散列表的好处而支持此方法，例如由HashMap提供的HashMap 。

hashCode的总合同是：

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

尽可能合理实用，类Object定义的hashCode方法确实为不同的对象返回不同的整数。 （这通常通过将对象的内部地址转换为整数来实现，但Java ^TM编程语言不需要此实现技术。）

toString

String toString ()

返回对象的字符串表示形式。 通常， toString方法返回一个“文本表示”此对象的字符串。 结果应该是一个简洁但内容丰富的表述，对于一个人来说很容易阅读。 建议所有子类重写此方法。

类Object的toString方法返回一个字符串，其中包含对象为实例的类的名称，符号字符“ @ ”以及对象的哈希代码的无符号十六进制表示形式。 换句话说，这个方法返回一个字符串，其值等于：

 getClass().getName() + '@' + Integer.toHexString(hashCode())
