java5之前我们可以通过java提供的tools.jar来操作java编译器,java6提供了新的API,让我们可以更方便的调用。包名为javax.tools。 使用 通过文件编译 StringfilePath="D:\\Client.java";//获取java编译器JavaCompilerjavaCompiler=ToolProvider.getSystemJavaCompiler();//编译intresult=javaCompiler.run(null,null,null,...
compile file是编译的意思,run application for current file是运行的意思.选择compile file时只会将.java文件编译成.class文件.而选择run application for current file则会看下文件是.java文件还是.class文件?如果是.java文件,则会先编译成.class文件,再运行;如果是.class文件,就直接运行.楼...
第一个想到的实现方式就是注解,但之前用的最多的注解类型是RUNTIME类型的,可以结合spring,反射+point实现注解逻辑,但编译时注解怎么操作?原理是javac编译的过程是一个独立的虚拟机进程,jdk提供了一个AbstractProcessor留给我们去继承重写相关方法(熟悉设计模式的估计已经想到模板模式了),达到编译时执行我们的注解处理器逻...

This was a new installation in my spare computer in order to migrate my project from Java 10 to 12. The migration succeded and the project runs fine. However, Intellij cannot resolve methods in most of my classes. It compiles, runs and Maven does not complain. I ...
a software program called a compiler, which takes the source code and translates it into executable instructions for the computer to carry out. the result of this process is usually an executable file, which can be run on the target machine or platform. what are some advantages of a compile...
