* By convention, the object returned by this method should be independent * of this object (which is being cloned). To achieve this independence, * it may be necessary to modify one or more fields of the object returned * by {@codesuper.clone} before returning it. Typically, this means ...
众所周知,所有 Java 类均继承了 Object 类,在 Object 类中定义了一个 getClass() 方法,该方法返回同一个类型为 Class 的对象。 ClasslabelCls=label1.getClass();// label1为 JLabel 类的对象 利用Class 类的对象 labelCls 可以访问 labelCls 对象的描述信息、JLabel 类的信息以及基类 Object 的信息 如表...

What I'd like to be able to do is loop through all of the get methods, automatically placing them in as key/value pairs. You can do this with reflection, but is there an easier, less resource intensive way to do it?.
* <p> * The current thread must own this object's monitor. The thread * releases ownership of this monitor and waits until another thread * notifies threads waiting on this object's monitor to wake up * either through a call to the {@code notify} method or the * {@code notifyAll} ...
迭代器是一种scanning through一系列元素,每次一个的一种软件设计模式。底层的迭代元素可能是被一个容器类所存储,也有可能是经过一系列的运算生成的。 Java针对迭代器定义了java.util.iterator接口,定义有如下2个方法: 这个接口使用了java的泛型变成,next方法会返回一个参数化的元素。 如果next方法在容器中没有元素 ...
