<strong>public IntStream chars()</strong>

import java.util.stream.IntStream;

public class StringCharsMethodTest {
   public static void main(String args[]) {
      String str = "Welcome to TutorialsPoint";
      IntStream intStream = str.<strong>chars()</strong>;
      intStream.forEach(x -> System.out.printf("-%s", (char)x));
   }
}
