在java中创建线程的各种方法的总结

前言

我总结了各种去创建线程的方法，分享给大家。并给出一些创建方式的代码。

给出一些创建方式的代码 

第6种

import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;

class MyCallable implements Callable<Integer> {

    @Override
    public Integer call() throws Exception {
        int sum=0;
        for(int i=1;i<=100;i++){
            sum=sum+i;
        }
        return sum;
    }
}
public class demo49 {

    public static void main(String[] args) throws InterruptedException, ExecutionException {
        MyCallable myCallable=new MyCallable();
        FutureTask<Integer> futureTask=new FutureTask<>(myCallable);
        Thread t=new Thread(futureTask);
        t.start();
        t.join();
        System.out.println("sum="+futureTask.get());

    }
}

import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;

public class demo48 {
    public static void main(String[] args) throws InterruptedException, ExecutionException {
        Callable<Integer> callable=new Callable<Integer>() {
            @Override
            public Integer call() throws Exception {
                int sum=0;
                for(int i=1;i<=100;i++){
                    sum=sum+i;
                }
                return sum;
            }
        };
        FutureTask<Integer> futureTask=new FutureTask<>(callable);
        Thread t=new Thread(futureTask);
        t.start();
        t.join();
        System.out.println("sum="+futureTask.get());
    }
}

第8种 

import java.util.concurrent.*;

public class demo50 {
    public static void main(String[] args) throws ExecutionException, InterruptedException {
        ExecutorService executorService=Executors.newFixedThreadPool(1);
        FutureTask<Integer> futureTask= (FutureTask<Integer>) executorService.submit(new Callable<Integer>(){
            @Override
            public Integer call() throws Exception {
                int sum=0;
                for(int i=1;i<=100;i++){
                    sum=sum+i;
                }
                return sum;
            }
        });
        executorService.shutdown();
        System.out.println("sum="+futureTask.get());

    }
}
