下面是使用BufferedReader实现按字节读取文件内容的示例代码: importjava.io.*;publicclassFileByteReader{privateStringfilePath;privateBufferedReaderbufferedReader;privateStringBuilderdataBuffer;privateStringstate;publicFileByteRea
在Java中,我们可以使用InputStream类和BufferedReader类来将字节流转换为字符串。下面是一个简单的示例代码: importjava.io.InputStream;importjava.io.InputStreamReader;importjava.io.BufferedReader;publicclassByteToString{publicstaticStringbyteToString(InputStreamis){BufferedReaderbr=newBufferedReader(newInputStreamRe...

2、InputStream–>String inputStream input =null; StringBuffer out=newStringBuffer();byte[] b =newbyte[4096];for(intn; (n = input.read(b)) != -1;) { out.append(newString(b, 0, n)); }returnout.toString(); 3、Reader –>String BufferedReader in =newBufferedReader(newInputStreamRea...
byte[] bs = new byte[1024 * 10240]; int count = 0; //循环把源文件的内容写入新文件 while ((count = in.read(bs, 0, bs.length)) != -1) { out.write(bs, 0, count); } //关闭流 out.flush(); out.close(); in.close(); ...

BufferedReader bufferedReader = new BufferedReader(inputSteamReader); 下面首先是通过字符流对文件进行读取和写入: 1 package lib; 2 3 import java.io.BufferedReader; 4 import java.io.File; 5 import java.io.FileNotFoundException; 6 import java.io.FileReader; ...
writeBytes("Thas was pi:writeByte/n"); out2.close(); DataInputStream in5 = new DataInputStream( new BufferedInputStream( new FileInputStream("F://nepalon// Data.txt"))); BufferedReader in5br = new BufferedReader( new InputStreamReader(in5)); System.out.println(in5.readDouble());...
使用InputStreamReader isr = new InputStreamReader(inp);BufferedReader reader = new BufferedReader(isr);可以调用 reader.readLine()方法 字节
