How to convert InputStream to String in Java?

Code:

import java.io.*;
 
public class InputStreamToString {
 
   public static void main(String[] args) throws IOException {
 
      String str = "Do you like green eggs and ham. I do not like them, Sam I am.";
      InputStream is = new ByteArrayInputStream(str.getBytes());
      String result = getStringFromInputStream(is);
      System.out.println(result);
   }
 
   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();
   }
}

Output:

$ java InputStreamToString
Do you like green eggs and ham. I do not like them, Sam I am.
