    Default How to put all char in loop to string?

    I can't figure out how to have all of the random characters generated to go into the String. Below I can only get the last character to covert over to a String.

    Thanks in advance!

    System.out.println("Original random character string:");
            String printingString = "a";
     
            for (int i = 0; i < 50; i++)//loop to obtain 50 random characters
            {
                char randomChar = (char) ((Math.random() * 255) +32);
                System.out.print(randomChar);
                printingString = Character.toString(randomChar);  
            } 
     
            return printingString;
        }

    Use concatenation. Start with a String with an initial value and concatenate each new character to it.
    The + is the concatenation operator: "A" + "B" gives "AB"
