Thread.currentThread()与this的区别【待完善】

package grammar.Thread.Chapter1;


public class CountOperate extends Thread {
    public CountOperate(){
        System.out.println("CountOperate - begin");
        System.out.println("Thread.getCurrentThread().getName() = " + Thread.currentThread().getName());
        System.out.println("Thread.getCurrentThread().isAlive() = " + Thread.currentThread().isAlive());
        System.out.println("Thread.currentThread().getClass() = "+Thread.currentThread().getClass()+"\n\n");


        System.out.println("this.getName() = " + this.getName());
        System.out.println("this.isAlive() = " + this.isAlive());
        System.out.println("this.getClass() is = "+this.getClass());
        System.out.println("CountOperate - end\n\n");
    }

    @Override
    public void run() {
        System.out.println("run  - begin");
        System.out.println("Thread.getCurrentThread().getName() = " + Thread.currentThread().getName());
        System.out.println("Thread.getCurrentThread().isAlive() = " + Thread.currentThread().isAlive());
        System.out.println("Thread.currentThread().getClass() = "+Thread.currentThread().getClass()+"\n\n");


        System.out.println("this.getName() = " + this.getName());
        System.out.println("this.getClass() is = "+this.getClass());
        System.out.println("this.isAlive() = " + this.isAlive());
        System.out.println("run - end\n\n");
    }
}

package grammar.Thread.Chapter1;

public class Test {
    public static void main(String[] args) {
        CountOperate c = new CountOperate();
        Thread t1 = new Thread(c);

        System.out.println("Main begin t1 isAlive = " + t1.isAlive());
        t1.setName("A");
        t1.start();
        System.out.println("Main end t1 isAlive = "+ t1.isAlive());
    }
}

执行结果如下：

CountOperate - begin
Thread.getCurrentThread().getName() = main
Thread.getCurrentThread().isAlive() = true
Thread.currentThread().getClass() = class java.lang.Thread


this.getName() = Thread-0
this.isAlive() = false
this.getClass() is = class grammar.Thread.Chapter1.CountOperate
CountOperate - end


Main begin t1 isAlive = false
Main end t1 isAlive = true
run  - begin
Thread.getCurrentThread().getName() = A
Thread.getCurrentThread().isAlive() = true
Thread.currentThread().getClass() = class java.lang.Thread


this.getName() = Thread-0
this.getClass() is = class grammar.Thread.Chapter1.CountOperate
this.isAlive() = false
run - end
