ideadongjvm

环境：idea + jdk8 + maven

代码中写了一个helloworld

public class HelloWorld {

public static void main(String[] args) {
    int i = 2;
    System.out.println(i);
   // System.out.println("welcome dongfucai hello world");
}

}

运行JJVM：结果如下

meituan/dong/jvm/HelloWorld.main@0:ICONST_2

meituan/dong/jvm/HelloWorld.main@1:ISTORE_1

meituan/dong/jvm/HelloWorld.main@2:GETSTATIC

meituan/dong/jvm/HelloWorld.main@3:ILOAD_1

meituan/dong/jvm/HelloWorld.main@4:INVOKEVIRTUAL

meituan/dong/jvm/HelloWorld.main@5:RETURN
