关于Java中一个class的contract指的是什么
rt
是constract把！构造方法！
哈哈 LZ写错了
construct 构造,建造,想出
constract 合同
通常用constructor 说是 构造器,构造函数
contract吧,就是public修饰的东西(一般是方法吧),就是对外承诺的接口.
学习学习....
恩，我看的是英文版的Java书，里面的有些词汇用字典翻译不对的，只能问各位大侠了
construct 对类本身来说是做些 初始化 工作，
对于 用它的类 是 在堆上创建对象。。。
找到一个完整的contract解释，不过还是有点不明白
Object-oriented programming strictly separates the notion of what is to be done from how it is done. "What" is described as a set of methods (and sometimes publicly available data) and their associated semantics. This combinationmethods, data, and semanticsis often described as a contract between the designer of the class and the programmer who uses it because it says what happens when certain methods are invoked on an object. This contract defines a type such that all objects that are instances of that type are known to honor that contract.
A common assumption is that the methods declared in a class are its entire contract. The semantics of those operations are also part of the contract, even though they may be described only in documentation. Two methods may have the same name and parameters and throw the same exceptions, but they are not equivalent if they have different semantics. For example, not every method called print can be assumed
