AGENT中JAVA语法问题

Question

本在做AGENT程序,从网站上得到下面的程序,可运行.
public void setup(){
        SimpleBehaviour decative = new SimpleBehaviour(this){
                
                boolean finished = false;
                int state = 0; 
                
                public void action(){
                        switch(state){
                                case 0:
                                System.out.println("Do");
                                break;
                                case 1:
                                System.out.println("Re");
                                break;
                                case 2:
                                System.out.println("Me");
                                
                                finished = true;
                                break;
                                
                        }
                        state++;
                }
                
                public boolean done(){
                        return finished;
                }
        };
本人对最后这个分号不明白,JAVA语法好像不支持这样的写法啊.还有这样一段,
protected void setup() {
System.out.println("Agent " + getLocalName() + " started."); // Add the CyclicBehaviour
addBehaviour(new CyclicBehaviour(this) {
public void action() {
System.out.println("Cycling");
}
});
这段后面也是同样的问题,还有个括号,它与那个对应呢?

Answer 1

那个分号是结束第二行开始的statement。研究一下Anonymous Inner Class就明白了。
