Java允许我们将其他static初始化工作划分到类内一个特殊的“static构建从句”(有时也叫作“静态块”)里。 它看起来象下面这个样子: class Spoon { static int i; static { i = 47; } 4. 非静态实例的初始化 针对每个对象的非静态变量的初始化,Java 1.1提供了一种类似的语法格式。 --- 如希望句柄得到初始...
When to use static method in a java class First , please understand its feature : * no need to instantiate a instance, i.e. simply you can just write: AutoTrace.start(); * All instances will share one static method, consider the consistency when the method operate a static (global) va...

Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. But these can also be overused and fall into some common pitfalls. To get a better understandi...
1)为什么接口中的属性都默认为static和final?Sun公司当初为什么要把java的接口设计发明成这样?【新手可忽略不影响继续学习】 答:马克-to-win:接口中如果可能定义非final的变量的话,而方法又都是abstract的,变量的修改就需要实现类来完成。马克-to-win,这样一来就有悖于Sun公司开始设计interface的初衷。interface就像一...
3. Use Java static imports Static imports are introduced in Java 5. Using static imports you can import static members/properties of a class so that you can directly access them without prefixing it's parent class's name. So, we can define a *Constants *class as shown in first approach...
