public class Test{
static int total=10;
public static void main(String args[]){
new Test();
}

public Test(){
System.out.println(this);
System.out.println("In test");
int temp=this.total;
if(temp>5){
System.out.println(temp);
}
}
}
程序执行完后,会有以下输出:
Test@ad3ba4
In Test
10
请问第一行输出是什么意思,怎么讲? 多谢!!!!!!!!!!!!!!

Posted by: didongusa Posted on: 2004-05-26 11:59 I think the instance name is a handle actually. A handle is a ptr to a group of pointers. As for what kind of pointers they are, much depends on the design of the JVM. I am not java master, just try to mess the simple thing.
