本文介绍了一个使用Java进行文件读取的例子，并展示了如何将读取到的字节流转换为字符串。通过实例代码，讲解了BufferedInputStream与ByteArrayOutputStream的用法。

public class Test{
public static void main(String[] args){
char[] data={a,b,c};
String s=new String(data);
System.out.println(s);
}
}

package cn.rg.demo.test;

import java.io.BufferedInputStream;
import java.io.ByteArrayOutputStream;
import java.io.FileInputStream;
import java.io.IOException;

public class writeFile {
public static void main(String[] args) throws IOException {

BufferedInputStream in = new BufferedInputStream(new FileInputStream("C:/Documents and Settings/iwin/桌面/work/ff85c21a4810499abc09854397b85c47.html"));
ByteArrayOutputStream out = new ByteArrayOutputStream(1024);

System.out.println("Available bytes:" + in.available());

byte[] temp = new byte[1024];
int size = 0;
while ((size = in.read(temp)) != -1) {
out.write(temp, 0, size);
}
in.close();

byte[] content = out.toByteArray();
String s=new String(content);
System.out.println(s);
System.out.println("Readed bytes count:" + content.length);
}
}
