本文探讨了在Java中实现多线程的两种方式：继承Thread类和实现Runnable接口。通过示例代码ThreadADemo、ThreadBDemo和ThreadCDemo，详细解释了两种方法的创建和启动过程，分析了各自的优缺点和适用场景。

1：项目结构

2：代码块

1：demo1

package tianyi.demo;
/**
 * @Title：${贾天一}
 * @Description: [娱乐]
 */
public class demoi1 {


    public static void main(String[] args) {

        //子线程A
        Thread t = new Thread(new ThreadADemo(),"子线程AThreadAAAName");
        t.start();

        //子线程B
        Thread t1 = new Thread(new ThreadBDemo(),"子线程BThreadBBBName");
        t1.start();

        //子线程C
        ThreadCDemo t2= new ThreadCDemo("子线程CThreadCCCName");
        t2.start();

        //主线程
        for(int i=0;i<=100;i++){

            System.out.println("HelloWorld"+i);
        }





    }

}

2:ThreadADemo

package tianyi.demo;



/**
 * @Title：${贾天一}
 * @Description: [娱乐]
 */
public class ThreadADemo implements Runnable{

    @Override
    public void run() {

        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        for (int i=0;i<=100;i++){

            System.out.println(Thread.currentThread().getName()+"\t"+i);
            //获取当前项目的名称

        }


    }
}

3:ThreadBDemo

package tianyi.demo;

/**
 * @Title：${贾天一}
 * @Description: [娱乐]
 */
public class ThreadBDemo implements Runnable{

    @Override
    public void run() {

        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        for (int i=0;i<=100;i++){

            System.out.println(Thread.currentThread().getName()+"\t"+i);
        }


    }
}

4:ThreadCDemo

package tianyi.demo;

/**
 * @Title：${贾天一}
 * @Description: [娱乐]
 */
public class ThreadCDemo extends Thread {

    private String name;
    public ThreadCDemo(String name){
        this.name =name;
    }


    @Override
    public void run() {

        for(int i=0;i<=100;i++){

            System.out.println(this.name+i);
        }

    }
}
