How to convert Inputstream as String using Java

In this article we will discuss about. How Java can do conversion from InputStream Object into String using Java core libraries.

  package com.onlinecodegeek.java.core;
         import java.io.BufferedReader;
    import java.io.ByteArrayInputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
         public class InputStreamToStringExample {
         public static void main(String[] args) throws IOException {
      InputStream is =                          new ByteArrayInputStream("file content..blah blah".getBytes());
         String result = getStringFromInputStream(is);
         System.out.println(result);
    System.out.println("Done");
         }
      private static String getStringFromInputStream(InputStream is) {
         BufferedReader br = null;
    StringBuilder sb = new StringBuilder();
         String line;
    try {
         br = new BufferedReader(new InputStreamReader(is));
    while ((line = br.readLine()) != null) {
    sb.append(line);
    }
         }
 catch (IOException e) {
    e.printStackTrace();
    }
 finally {
    if (br != null) {
    try {
    br.close();
    }
 catch (IOException e) {
    e.printStackTrace();
    }
    }
    }
         return sb.toString();
         }
         }
