java在线java在线编译器实现

用java写，在线

public?class?Book{ private?String?title; private?String?author; private double?price; public?Book(){ } public?Book(String?title,String?author){ this.title=title; this.author=author; } public?Book(String?title,String?author,double?price){ this.title=title; this.author=author; this.price=price; } public?void?info(){ System.out.println("书名:"+title); System.out.println("作者:"+author); System.out.println("价格:"+price); } }

java在线编译器实现

try{ Thread.sleep(1000); }catch(InterruptedException e){ //扑捉发生在线程中的异常，当一个正在执行的线程被中断时就会出现这个异常，添加catch后当程序被双击停止时不会出现错误 e.printStackTrace(); } lbClock.setText(getDate()); }
