Java – Convert InputStream to String

Recently, i have created a simple Java Servlet server which could parse a request xml from the HTTP POST Request and then return the HTTP Response together with the response xml. In the server implementation, i need to convert an InputStream into a String. The following code shows you how to make it.

In this example, the program will read the data.txt file and print the content to the console.


public class ConvertInputStreamToString {
	public static void main(String[] args) throws IOException {
		InputStream is = null;
		StringBuilder sb = new StringBuilder();
        String line;
		try {
			ConvertInputStreamToString cists = new ConvertInputStreamToString();
			is = cists.getClass().getResourceAsStream("data.txt");
			BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
            while ((line = reader.readLine()) != null) {
            // Print the content of data.txt
		} catch (Exception e) {
		} finally {


Here is what you get after running the ConvertInputStreamToString class.


Done =)
