import java.io.*; public class NewApp006 { public static void main(String[] args) { try { InputStreamReader vInputStreamReader = new InputStreamReader(System.in); BufferedReader vBufferedReader = new BufferedReader(vInputStreamReader); System.out.println("请输入文本，按回车结束："); String sInput = vBufferedReader.readLine(); sInput = "\r\n"+sInput; String sFile = "D:\\temp\\test.txt"; RandomAccessFile vRandomAccessFile = new RandomAccessFile(sFile,"rw"); long lLen = vRandomAccessFile.length(); vRandomAccessFile.seek(lLen); vRandomAccessFile.writeBytes(sInput); vRandomAccessFile.close(); } catch(Exception e) { System.out.println("系统发生错误。"); } System.out.println("程序结束。"); } }
