Java 多线程 简单例子

因为工作需要，需要在同一时间执行多次某个操作，看看是否会引起数据的deadlock文件。

多线程具体执行类

package com.ericyang.test.cmdline;
import java.util.List;
import java.text.SimpleDateFormat; 
import java.text.DateFormat; 
import java.util.Date; 
class ThreadClass  extends xxxTestBase implements Runnable{  
   private static  String[] Import_args;
   
   public ThreadClass(String[] args){
      Import_args = args;
   }
    
    public void run()  
   { 
      SimpleDateFormat bartDateFormat = 
      new SimpleDateFormat("EEEE-MMMM-dd-yyyy"); 
	  DateFormat shortDateFormat = 
        DateFormat.getDateTimeInstance( 
        DateFormat.SHORT, 
        DateFormat.SHORT); 
      Date date = new Date(); 
      System.out.println(bartDateFormat.format(date));
	    System.out.println("Thread starting time:"+shortDateFormat.format(date));
	 try { 
	     runCmd(Import_args);
	 }catch (Exception ex) { 
            System.out.println(ex.getMessage()); 
     } 
     System.out.println("Thread ending time:"+shortDateFormat.format(date));
   }
} 

/*xxxTestBase 是我的一个执行基类，它有函数 runCmd(Import_args);可以具体执行一些命令行操作*/

    /**

     */
    public void runMultiCmd() throws Exception {
		
		String[] args = {"-U", "yq",
                "-P", "qq",
                "-x", IMPORT_FILE, "-p", "-I", "-e", "-f"};			
		ThreadClass t = new ThreadClass(args);
        Thread thread = new Thread(t);
        thread.start();
		
		String[] args2 = {"-U", "yq1",
                "-P", "qq",
                "-x", IMPORT_FILE2, "-p",};		
		ThreadClass t2 = new ThreadClass(args2);
        Thread thread2 = new Thread(t2);
        thread2.start();
		
		
		String[] args3 = {"-U", "yq2",
                "-P", "qq",
                "-x", IMPORT_FILE3, "-p",};		
		ThreadClass t3 = new ThreadClass(args3);
        Thread thread3 = new Thread(t3);
        thread3.start();
		
    }
 }

每个需要多线程执行类似的命令行的都可以以上方式执行。
