源码：
public class Main
{
public void main(String[] args)
{
int a = (int) 3.14;
a++;
a=a+1;
a=a+2;
System.out.println(3+4);
List list = new ArrayList();
list.add(1);
List<String> list2 = new ArrayList<String>();
list2.add("333");
}
}
反编译以后：
public class Main
{
public void main (String[] args)
{
int a = 3;
a++;
a++;
a += 2;
System.out.println (7);
java.util.List list = new ArrayList ();
list.add (Integer.valueOf (1));
java.util.List list2 = new ArrayList ();
list2.add ("333");
}
}
