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:

Code:

The method length() in the type String is not applicable for the arguments (String)

all i have typed in is this:

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.

kind regards,

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:

Code:

String s= "foo";

Its length is found here:

Code:

System.out.println("length: "+s.length());

See? No parameters for that method.
