类(class):类是Java的基础编程单元。类是静态方法、非静态方法和变量的集合。静态成员是类自身的一部分,非静态或“实例”成员是创建对象的蓝本,由此创建的对象“属于”该类。 类变量(class variable)和类方法(class methods):“静态变量”和“静态方法”的别名。它们是类的一部分,与对象无关。 客户端/服务器(cl...
The syntax of Java refers to the set of rules defining how a Java program is written and interpreted, while the Java code style serves more as a coding standard and guideline. Syntax和style是两个完全不同的概念。Syntax指的是固定的Java语法,而style代表的是代码风格。如果一段代码中syntax错误,编...
抽象语法树(Abstract Syntax Tree,AST): 是一种用来描述程序代码语法结构的树形表示方式; 每个节点都代表程序代码中的一个语法结构; 语法结构(Construct)包括:包、类型、修饰符、运算符、接口、返回值、甚至注释等; 2、源码分析: 由com.sun.tools.javac.parser.JavacParser类完成整个过程,该类实现com.sun.tools....

以下内容引用自http://wiki.jikexueyuan.com/project/java/basic-syntax.html: 一、概述: Java应用程序可以被定义为对象的集合,这些对象通过调用各自的方法来进行通信。 对象(Object):对象具有状态和行为。例如:狗有它的状态—颜色,名字,品种,同时也有行为—摇尾巴,汪汪叫,吃东西。对象是类的一个实例。
Java - Basic Syntax - When we consider a Java program, it can be defined as a collection of objects that communicate via invoking each other's methods. Let us now briefly look into what do class, object, methods, and instance variables mean.
