和文件的读取操作类似,不同的是构造函数中是用 byte[]来初始化 ByteArrayInputStream
package com.machuang.io.others;
import java.io.BufferedInputStream;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
public class ByteArray {
public static void main(String[] args) throws IOException {
byteArrayRead();
}
public static void byteArrayRead() throws IOException {
// 创造字节数组,(从服务器或者其他主机上传来的 byte[])
String msg = "和文件读取操作一样";
byte[] msgBytes = msg.getBytes(); // 待读取的字节数组
InputStream bis = new BufferedInputStream( new ByteArrayInputStream(msgBytes) );
// byteBuf
byte[] byteBuf = new byte[1024];
int len = 0;
// 读取操作
while(-1 != (len = bis.read(byteBuf))) {
System.out.println(new String(byteBuf, 0, len));
}
bis.close();
}
}
