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();
}
}
