java98-线程join使用中断进行另一个

public class test33 {
public static void main(String[] args) {
Xc46 xc46=new Xc46();
Thread dd = new Thread(xc46);
dd.start();

try {
dd.join();
} catch (Exception e) {
}
for (int i=0;i<15;i++) {
System.out.println("主函数"+i);
}
}
}
class Xc46 implements Runnable {
public void run() {
for (int i = 0; i < 30; i++) {
System.out.println( "歌谣" + i);
}
}
}

运行结果
