输出流转字符串

import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; public class IOAnswer { public static void main(String[] args) { String str = "Hello,ABC"; //源字符串 //字节数组输入流 ByteArrayInputStream bais = new B...

public static byte[] getFileToByte(File file) { byte[] by = new byte[(int) file.length()]; try { InputStream is = new FileInputStream(file); ByteArrayOutputStream bytestream = new ByteArrayOutputStream(); byte[] bb = new byte[2...

1. InputStream 和OutputStream,两个是为字节流设计的,主要用来处理字节或二进制对象, 2. Reader和 Writer.两个是为字符流(一个字符占两个字节)设计的,主要用来处理字符或字符串. 字符流处理的单元为2个字节的Unicode字符,分别操作字符、字符...

代码如下: /** * 将一个字符串转化为输入流 */ public static InputStream getStringStream(String sInputString){ if (sInputString != null && !sInputString.trim().equals("")){ try{ ByteArrayInputStream tInputStringStream = new ByteA...

public static byte[] getFileToByte(File file) { byte[] by = new byte[(int) file.length()]; try { InputStream is = new FileInputStream(file); ByteArrayOutputStream bytestream = new ByteArrayOutputStream(); byte[] bb = new byte[2...

这个问题要分2个部分 字节流和字符流之间的转换 字节流转换成字符流可以用InputSteamReader/OutputStreamWriter相互转换 2.怎么把字符串转为流. 下面的程序可以理解把字符串line 转为流输出到aaa.txt中去 FileOutputStream fos = null;fos = new...

HttpServletRequest.getInputStream() 获取到inputstream之后,在用StringBuffer和char[]来转换。

public class ByteTest { public static void main(String[] args) { String str = "Hello world!"; // string转byte byte[] bs = str.getBytes(); System.out.println(Arrays.toString(bs)); // byte转string String str2 = new String(bs); Sy...
