Java读取文件内容并转换为字符串

        String FileName = " d:/2.txt " ;
        File myFile
= new  File(FileName);
        
if ( ! myFile.exists())
        

            System.err.println(
"Can't Find " + FileName);
        }


        
try  
        
{
            BufferedReader in 
= new BufferedReader(new FileReader(myFile));
            String str;
            
while ((str = in.readLine()) != null
            
{
                  System.out.println(str);
            }

            in.close();
        }
 
        
catch  (IOException e) 
        
{
            e.getStackTrace();
        }
