在main 方法中,在每个 LibClass 选择acrostic(String[]args) 方法,然后按回车键。IDE 将填充 acrostic 方法,并突出显示 args 按回车键接受 args 键入一个分号。 最终得到的行应如下所示: String result = LibClass.acrostic(args); 按回车键开始一个新行。然后键入 sout 并按 Tab 键。缩写 sout 将扩展为 Sy...

值得一提的是,Substrate VM虽然名为VM,但并不是一个虚拟机,而是一个包含了 垃圾回收、线程管理 等功能的运行时组件(Runtime Library),就好比C++当中的stdlib一样。当Java程序被编译为Native Image运行的时候,并不是运行在Substrate VM里,而是将SubstrateVM当作库来使用其提供的各种基础能力,以保障程序的正常运行。
