Java中的IO流（BufferedinputStream）

BufferedinputStream:

字节缓冲输入流
与BufferedinputStream相似

public static void main(String[] args) throws IOException {
		//1:创建字节缓冲输入流  (包装流，底层包装的是字节缓冲流)
		BufferedInputStream bis = new BufferedInputStream(new
		 FileInputStream("c.txt"));
		//2:读取数据
		 //2.1 一次读取一个字节
		/* int read = bis.read();
		 System.out.println((char)read);*/
		/*int num = 0;
		while((num = bis.read())!=-1){
			System.out.print((char)num);
		}*/
		 //2.2 一次读取一个字节数组
		int num = 0;
		 byte[] by = new byte[1024];
		 while((num = bis.read(by))!=-1){
			 System.out.print(new String(by,0,num));
		 }
		//3:关闭流
		bis.close();
