Java题库练习!!!
public class ThreadRunnable implements Runnable{
int count = 1,number;
public ThreadRunnable(int num) {
number=num;
System.out.println("创建线程 "+number);
}
public void run(){
while(true){
System.out.println("线程 "+number+":计数"+count); if(++count==3) return;
}
}
public static void main(String[] args) {
new myThread(1).start();
}
}
程序运行的结果是：
创建线程 1线程 1:计数1 线程 1:计数2
3.
public class test implements Runnable{
public void run(){
for(int i=3;i<=15;i++){
if(isPrime(i))
System.out.print(i+"\t");
}
}
