本文提供了一个Java线程的实现案例，包括使用Thread类创建线程和实现Runnable接口两种方式，并展示了如何启动这些线程。

package thread;

public class FirstThread {

	public static void main(String[] args) {
		System.out.println("123112");
		Thread t = Thread.currentThread();
		System.out.println(t.getName());
		System.out.println(t.getPriority());
		System.out.println(t.getThreadGroup());
		System.out.println(t.getState());
	}

}

123112
main
5
java.lang.ThreadGroup[name=main,maxpri=10]

RUNNABLE

package thread;

public class NumberThread extends Thread{
	int value;
	
	public NumberThread(int value) {
		this.value = value;
	}
	
	@Override
	public void run() {
		for(int i=0; i<20; i++){
			System.out.println(getName()+ "--" + value);
			value+=2;
		}
	}
	
}

package thread;

public class NumberRunnable implements Runnable{

	int value;
	
	public NumberRunnable(int value) {
		this.value = value;
	}


	@Override
	public void run() {
		for(int i=0; i<20; i++){
			System.out.println(Thread.currentThread().getName()+ "--" + value);
			value+=2;
		}
	}
	
}

package thread;

public class FirstThread {

	public static void main(String[] args) {
//		System.out.println("123112");
//		Thread t = Thread.currentThread();
//		System.out.println(t.getName());
//		System.out.println(t.getPriority());
//		System.out.println(t.getThreadGroup());
//		System.out.println(t.getState());
		
		NumberThread even = new NumberThread(0);
		//NumberThread odd = new NumberThread(1);
		NumberRunnable r = new NumberRunnable(1);
		Thread odd = new Thread(r, "奇数线程");
		even.setName("偶数线程");
		even.start();
		odd.start();
		System.out.println("main线程结束");//两个线程竞争cpu资源
	}
