Given a Instream containing ASCII values, the task is to convert this Instream into a String containing the characters corresponding to the ASCII values.

Examples:

Input: IntStream = 71, 101, 101, 107, 115
Output: Geeks

Input: IntStream = 71, 101, 101, 107, 115, 70, 111, 114, 71, 101, 101, 107, 115
Output: GeeksForGeeks

Algorithm:

  1. Get the Instream to be converted.
  2. Convert the IntStream into String with the help of StringBuilder
  3. Collect the formed StringBuilder
  4. Convert the StringBuilder into String using toString() methods.
  5. Print the formed String.

Below is the implementation of the above approach:




// Java program to convert
// String to IntStream
  
import java.util.stream.IntStream;
  
class GFG {
    public static void main(String[] args)
    {
  
        // Get the String to be converted
        IntStream intStream = "Geeks".chars();
  
        // Convert IntStream to String
        String string = intStream
                            .collect(StringBuilder::new,
                                     StringBuilder::appendCodePoint,
                                     StringBuilder::append)
                            .toString();
  
        // Print the String
        System.out.println("String: " + string);
    }
}


Output:

String: Geeks
