InputStream into String. In the code snippet below we read a data.txt file, could be from common folder or from inside a jar file.package org.kodejava.example.io; import java.io.*; public class StreamToString { public static void main(String[] args) throws Exception { StreamToString sts = new StreamToString(); // Get input stream of our data file. This file can be in // the root of you application folder or inside a jar file // if the program is packed as a jar. InputStream is = sts.getClass().getResourceAsStream("/data.txt"); // Call the method to convert the stream to string System.out.println(sts.convertStreamToString(is)); } public String convertStreamToString(InputStream is) throws IOException { // To convert the InputStream to String we use the // Reader.read(char[] buffer) method. We iterate until the // Reader return -1 which means there's no more data to // read. We use the StringWriter class to produce the string. if (is != null) { Writer writer = new StringWriter(); char[] buffer = new char[1024]; try { Reader reader = new BufferedReader( new InputStreamReader(is, "UTF-8")); int n; while ((n = reader.read(buffer)) != -1) { writer.write(buffer, 0, n); } } finally { is.close(); } return writer.toString(); } return ""; } }
