我们可以直接调用run()方法代替Java中的start()吗?
是的,我们可以做到。让我们看一个例子-
示例
class my_thread extends Thread{public void run(){
try{
System.out.println ("The thread " + Thread.currentThread().getId() + " is currently running");
}
catch (Exception e){
System.out.println ("The exception has been caught");
}
}
}
public class Main{
public static void main(String[] args){
int n = 6;
for (int i=1; i<n; i++){
my_thread my_object = new my_thread();
my_object.run();
}
}
}
输出结果
The thread 1 is currently runningThe thread 1 is currently running
The thread 1 is currently running
The thread 1 is currently running
The thread 1 is currently running
名为“ my_thread”的类继承了主线程,其中定义了“运行”函数,该函数给出了正在运行的当前线程的ID。定义了一个try and catch块来捕获异常(如果有)并显示相关的错误。在主函数中,运行“ for”循环,并创建“ my_thread”类的新对象。在此对象上调用“运行”功能。
