public class test{
	public static void main(String[] args) {
		m1();
	}
	
	public static void m1() {
		m2();
		m3();
	}
	
	public static void m2() {
	
	}
	
	public static void m3() {
		
	}
}

进程是一个静态的概念，在我们机器里，实际运行的都是线程。



线程启动：

package com.zzk.test;

public class Test {
    public static void main(String[] args) {
    	Runner1 r=new Runner1();
    	//r.run();
    	Thread t=new Thread(r);
    	t.start();
    	
    	for(int i=0;i<100;i++) {
    		System.out.println("Main Thread:-----"+i);
    	}
    }
}



class Runner1 implements Runnable {
	public void run() {
		for(int i=0;i<100;i++) {
			System.out.println("Runner1 :"+i);
		}
	}
}

输出：

方法调用：

package com.zzk.test;

public class Test {
    public static void main(String[] args) {
    	Runner1 r=new Runner1();
    	r.run();
    	//Thread t=new Thread(r);
    	//t.start();
    	
    	for(int i=0;i<100;i++) {
    		System.out.println("Main Thread:-----"+i);
    	}
    }
}



class Runner1 implements Runnable {
	public void run() {
		for(int i=0;i<100;i++) {
			System.out.println("Runner1 :"+i);
		}

第二种创建方式

package com.zzk.test;

public class Test {
    public static void main(String[] args) {
    	Runner1 r=new Runner1();
    	//r.run();
    	//Thread t=new Thread(r);
    	r.start();
    	
    	for(int i=0;i<100;i++) {
    		System.out.println("Main Thread:-----"+i);
    	}
    }
}



class Runner1 extends Thread {
	public void run() {
		for(int i=0;i<100;i++) {
			System.out.println("Runner1 :"+i);
		}
	}
}
