输入输出流String间的转换

来自:http://wuhongyu.iteye.com/blog/806791

 

1.String  to  inputStream

InputStream is = new ByteArrayInputStream(string.getBytes());  

  

2.InputStream to String

      

ByteArrayOutputStream baos = new ByteArrayOutputStream();  

int i;  

while ((i = is.read()) != -1) {  

    baos.write(i);  

}  

String str = baos.toString();  

System.out.println(str); 

 3.String写入OutputStream

OutputStream os = System.out;  

os.write(string.getBytes());

 4.OutputStream写入String

ByteArrayOutputStream baos = new ByteArrayOutputStream();  

//向OutPutStream中写入,如 message.writeTo(baos);  

String str = baos.toString();
