已经完成了JAVA应用程序如何启动:命令行启动,并获取到了启动时需要的选项和参数。 但是,如果要启动一个最简单的“Hello World”程序(如下),也需要加载很多所需的类进入JVM中 publicclassHelloWorld{publicstaticvoidmain(String[] args){ System.out.println("Hello, world!"); } } 加载HelloWorld类之前,需要加载该...

On the Qshell command line, type java followed by HelloWorld to run your HelloWorld.class with the Java virtual machine. For example, enter java HelloWorld. You can also use the Run Java (RUNJVA) command on your system to run HelloWorld.class: RUNJVA CLASS(HelloWorld) "Hello World" prin...

这样就可以愉快的写Java代码了, 测试下,command+shift+p, 在里面输入Java: create Project,输入项目名,在src文件夹中,选择Run运行Java代码,控制台数据Hello World则为成功。 OK, Java配置完成。 这样下来, 就把Vscode打造成了能同时开发Python, C++以及Java项目的神器了, 当然, Vscode还能做更多语言的项目开发, ...
