    Default String.length?

    Hello, I am currently having some issues with the .length for Strings.

    Class: String
    IDE: Eclipse
    Error:The method length() in the type String is not applicable for the arguments (String)

    I am using Eclipse and i keep getting this error:
    Java Code:
    The method length() in the type String is not applicable for the arguments (String)
    all i have typed in is this:
    Java Code:
    String.[COLOR="Red"]length[/COLOR](hexadecimal);
    From what i can tell is that it should be working from the java api. But idk exactly what i am doing. haha it is very frustrating when you have worked on this for hours.

    The length() method doesn't take any arguments; also read what the compiler is trying to tell you. That method just returns the number of characters in the String.

    Per the Java API, does the length method take a parameter?

    How would you measure a String length then? I was looking for a Method to do so but if it doesn't take anything in, I am not sure what to use?

    Thanks for the help

    Assuming hexadecimal is the name of the string you're trying to find the length of, hexadecimal.length() will return its length.

    Suppose I have a String:

    Java Code:
    String s= "foo";
    Its length is found here:

    Java Code:
    System.out.println("length: "+s.length());
    See? No parameters for that method.

    kind regards,

    Jos
