Java Stream converting char to ascii

Question

so I all I want for this to do is to print out the chars instead of the ascii values...

     str.chars()
        .distinct()
        .forEach(System.out::println);

this is the output:

does anyone know how to fix this?

You can map the characters accordingly using the mapToObj method

str.chars().mapToObj(c -> (char)c).forEach(System.out::println);

You can do this by casting the int to char as below

str.chars()
        .distinct()
        .forEach(x -> System.out.println((char)x));

thank you! Could I use forEach to convert back to char and save in an array? – n_u_l_l Aug 14 '20 at 06:21
Yes definitely you can do it. Rather than printing it add it to char[]. like char[] cArray = new char[]. And then cArray[index] = (char)x – Gaurav Jeswani Aug 14 '20 at 06:23
