InputStream String in Java

When getting the input stream in Java, it is sometimes necessary to flow the input into a string in order to get its contents, and summarize the way InputStream turns into string

Method 1:

Public String convertstreamtostring (InputStream is) {

BufferedReader reader = new bufferedreader (new InputStreamReader (IS));

StringBuilder sb = new StringBuilder ();

String line = null;

Try {

while (line = Reader.readline ()) = null) {

Sb.append (line + "/n");

}

} catch (IOException e) {

E.printstacktrace ();

} finally {

Try {

Is.close ();

} catch (IOException e) {

E.printstacktrace ();

}

}

return sb.tostring ();

}

Method 2:

Public String inputstream2string (InputStream in) throws IOException {
StringBuffer out = new StringBuffer ();
Byte[] B = new byte[4096];
for (int n;   (n = in.read (b))! =-1;) {
Out.append (New String (b, 0, N));
}
return out.tostring ();
}

Method 3:
public static String inputstream2string (InputStream is) throws ioexception{
Bytearrayoutputstream BAOs = new Bytearrayoutputstream ();
int i=-1;
while ((I=is.read ())!=-1) {
Baos.write (i);
}
return baos.tostring ();
}
