This option is equivalent to -XX:ReservedCodeCacheSize. -Xmixed Executes all bytecode by the interpreter except for hot methods, which are compiled to native code. -Xmnsize Sets the initial and maximum size (in bytes) of the heap for the young generation (nursery). Append the letter k or...

Bytecode Viewer 上面我们按照JVM规范逐一解析了class文件的16进制内容,解析的结果得到了验证。JVM规范的本质就是在描述这件事,告知大家它是如何设定不同的区域所对应的字节码,如何通过这些字节码的规范去表示类、方法、字段等等,由此可以支持非常复杂的信息化需求。其实就是一本翻译书,我说”hello“,它告诉我是”打...

这里我们介绍一种可以在 Android Studio 中看 class 文件的插件 -jclasslib,代码编译后在菜单栏 "View" 中选择 "Show Bytecode With jclasslib",可以很直观地看到当前字节码文件的类信息、常量池、方法区等信息: Java 类型描述符 1.4 访问标志 紧跟在常量池之后的常量是访问标志,占用两个字节,如下图所示: ...
