A constructor is a named block of code that is used to initialize an object of a class immediately after the object is created. The general syntax for a constructor declaration is: <<Modifiers>><<ConstructorName>>(<<parameters list>>)throws<<Exceptionslist>>{// Body of constructor goes her...

可以预见的是,这个静态分析的过程(官方称之为 Pionts-to Analysis)是非常复杂且耗时的,整个分析过程会以递归的方式进行,最终得到两个树形结构Call Tree(包含所有可达的方法)以及Object Tree(包含所有可达的对象),Call Tree中所包含的方法会被AOT编译为机器码,成为Native Image的Text Section,而Object Tree中所包含的...

You can also create an object of a class and access it in another class. This is often used for better organization of classes (one class has all the attributes and methods, while the other class holds themain()method (code to be executed)). ...

For example, an application could create a network class loader to download class files from a server. Sample code might look like: <blockquote> text/java 複製 ClassLoader loader = new NetworkClassLoader(host, port); Object main = loader.loadClass("Main", true).newInstance...
