Java调用外部exe程序

用java调用.exe程序的方法:

public class Demo{
     public static void main(String args[]){
     Runtime rn = Runtime.getRuntime();
     Process p = null;
     String exeFile = "";
     try{
       exeFile = "D:\\EditPlus 2\\editplus.exe";
       p = rn.exec(exeFile);
     }catch( Exception e ){
       System.out.println( " ERROR exec Editplus.exe " );
     }
    }

}
