如何在文本文件当中实现按列读取？
写了半天提交时竟然出错，晕倒。。。只好把源代码贴上算了
publicstaticvoidconvert(){
longstart=System.currentTimeMillis();Filefile=newFile("test1.txt");
try{for(inti=0;i<COLS;i++){StringBufferline=newStringBuffer();FileInputStreamfis=newFileInputStream(file);DataInputStreamin=newDataInputStream(fis);in.skip(i);for(intj=i;j<ROWS*(COLS+2);j+=COLS+2){line.append((char)in.readByte());in.skip(COLS+1);
}fis.close();in.close();line.append(" ");GFFile.writeFile("test2.txt",line.toString(),true);System.out.println("write"+i);}}catch(FileNotFoundExceptione){e.printStackTrace();}catch(IOExceptione){e.printStackTrace();}System.out.println("time:"+(System.currentTimeMillis()-start));
}
