InputStream String in java

InputStream String in java

When obtaining an input stream in Java, you sometimes need to convert the input stream to a String to obtain the content. The following describes how to convert InputStream to a 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 ();
}
