无参数的多线程

每个线程处理10条数据

package org.jeecg.modules.gybmapi;

public class ThreadTask implements Runnable{

public void run() {

for (int i = 0; i < 10; i++) {

System.out.println(Thread.currentThread().getName() + "执行" + i);

}

}

}

启动50个线程

package org.jeecg.modules.gybmapi;

public class Main {

public static void main(String[] args) {

for (int i = 0; i < 50; i++) {

new Thread(new ThreadTask()).start();

}

}

2 带参数的多线程

启动2个线程，每个线程处理100条数据

2.1构造方法传参

package org.jeecg.modules.gybmapi;

public class Printer implements Runnable {

private String message;

public Printer(String message) {

this.message = message;

}

@Override

public void run() {

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

System.out.println(Thread.currentThread().getName() + "执行" + i +message);

}

}

}

2.2启动2个线程

package org.jeecg.modules.gybmapi;

public class Main {

public static void main(String[] args) {

//启动2 个线程

new Thread(new Printer("Good")).start();

new Thread(new Printer("Nice")).start();

}

}

2.3 set方法传参

package org.jeecg.modules.gybmapi;

public class Printer implements Runnable {

private String message;

public void setMessage(String message) {

this.message = message;

}

// public Printer(String message) {

// this.message = message;

// }

@Override

public void run() {

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

System.out.println(Thread.currentThread().getName() + "执行" + i +message);

}

}

}

2.4 启动2个线程

package org.jeecg.modules.gybmapi;

public class Main {

public static void main(String[] args) {

// for (int i = 0; i < 50; i++) {

// new Thread(new ThreadTask()).start();

// }

//启动2 个线程

Printer printer=new Printer();

printer.setMessage("Good");

Printer printer1=new Printer();

printer1.setMessage("Nice");

new Thread(printer).start();

new Thread(printer1).start();

}

}
