1.繼承Runnable介面
package com.vince.xq.kafka.thread;
public class ThreadOne implements Runnable {
private int i;
public ThreadOne(int i) {
this.i=i;
}
@Override
public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(i);
}
}
使用
package com.vince.xq.kafka;
import com.vince.xq.kafka.thread.ThreadOne;
public class TestThread {
public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
Thread thread = new Thread(new ThreadOne(i));
thread.start();
}
}
}
結果
2.繼承Thread 類
package com.vince.xq.kafka.thread;
public class ThreadTwo extends Thread {
private int i;
public ThreadTwo(int i){
this.i=i;
}
@Override
public void run() {
System.out.println(i);
}
}
使用
package com.vince.xq.kafka;
import com.vince.xq.kafka.thread.ThreadTwo;
public class TestThread {
public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
Thread thread = new ThreadTwo(i);
thread.start();
}
}
}
結果
3.繼承callable介面
package com.vince.xq.kafka.thread;
import java.util.concurrent.Callable;
public class ThreadThree implements Callable<String> {
@Override
public String call() {
try {
int x = 10 / 1;
return "test";
} catch (Exception e) {
e.printStackTrace();
return "0";
}
}
}
使用
package com.vince.xq.kafka;
import com.vince.xq.kafka.thread.ThreadThree;
import java.util.concurrent.*;
public class TestThread {
public static void main(String[] args) throws ExecutionException, InterruptedException {
ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(1, 1,
0L, TimeUnit.MILLISECONDS,
new LinkedBlockingQueue<Runnable>());
FutureTask<String> futureTask = new FutureTask<>(new ThreadThree());
threadPoolExecutor.submit(futureTask);
System.out.println(futureTask.get());
threadPoolExecutor.shutdown();
}
}
