How to determine whether a multi-level path exists in java and create it if it does not exist

方案一:

(带文件名的Path:如:D:\news\2014\12\abc.text)

例如:

public boolean isexitsPath(String path)throws InterruptedException{
      String [] paths=path.split("\\\\");
      StringBuffer fullPath=new StringBuffer();      
      for (int i = 0; i < paths.length; i++) {
                fullPath.append(paths[i]).append("\\\\");          
                File file=new File(fullPath.toString());          
                if(paths.length-1!=i){//判断path到文件名时,无须继续创建文件夹!              
                    if(!file.exists()){
                        file.mkdir();                  
                        System.out.println("创建目录为:"+fullPath.toString());                  
                        Thread.sleep(1500);              
                        }          
                }      
      }      
                        File file=new File(fullPath.toString());//目录全路径      
                        if (!file.exists()) {          
                            return true;      
                        }else{
                            return false;      
                        }  
}

注意:带文件名的path,需要判断是否path中已经包含文件名,若包含,则不再创建文件夹。
