如何把一段创建新线程的代码封装成一个类，然后另一个类中引用？如何引用？
package com.example.demo;
  
import java.util.concurrent.Callable;  
import java.util.concurrent.ExecutorService;  
import java.util.concurrent.Executors;  
import java.util.concurrent.Future;  
  
public class  trdSoap {  
  
    public static void main(String[] args) {  
     final String  rtnString = null ;
    
        ExecutorService executor = Executors.newFixedThreadPool(3);  
        try {  

            final Future<String> future2 = executor.submit(new Callable<String>() {  
                @Override  
                public String call() throws Exception {               
                    try {  
                        while (true) {  
                            System.out.println("demo");
                         Thread.sleep(50);                             
                        }  
                    } catch (InterruptedException e) {  
                    }  
                    return rtnString;  
                }  
            });  
              
        } catch (Exception e) {  
        }  

        executor.shutdownNow();  
    }  
    
    
    
}
