Read InputStream into String

Turn an arbitrary InputStream into a String using buffered read.

public static final int BUFFER_SIZE = 8192;

public static String readContent(InputStream in) throws IOException {
 final byte[] readBuffer = new byte[BUFFER_SIZE];

 StringBuilder sb = new StringBuilder();
 try {
 if (in.available() > 0) {
 int bytesRead = 0;
 while ((bytesRead = in.read(readBuffer)) != -1) {
 sb.append(new String(readBuffer, 0, bytesRead));
 }
 }
 } catch (IOException e) {
 throw e;
 } finally {
 try {
 in.close();
 } catch (IOException e) {
 throw e;
 }
 }

 return sb.toString();
}
