    Default Strings and Characters

    String String1 = new String();

    String1 = "bubble";

    String1.charAt(4);

    I want to input the result of String1.charAt(4); which is the letter l into a method which only takes a char as an argument.

    What line of code is required?

    What does the String charAt() method return?
    a method which only takes a char as an argument.
    String1.charAt(4) should work as is.

    What were you trying to do with this: String1.charAt(4) = char aChar;
    It looks reversed from what it should be.

    String1.charAt(4) should work as is. Yes it does, it returns the letter l, but then how do i input this result into another method that only takes a char as an
    argument.

    displayLetter(String1.charAt(4)) wont work , so what coding do i need? How do i assign the result to a value that displayLetter() can take as an argument?

    Have you tried it?

    How is displayLetter defined?
    Is it: displayLetter(char c)
