One error I can see is that you are trying to use equals to compare two integers. Primitive data types (such as int) don't have methods. You need to use == to compare them.

Fix that and if it still doesn't compile, post the error messages you are getting (exactly as they appear). Once it's compiling we can then tackle the logic.

I've made a few modifications -marked in bold- to help you get going. What's missing is the spot labelled "TODO". What needs to happen there to make the code work?

Hi
As pointed out by folks above, there are some erroes in your code.Find below a simple piece of code that achieves what your code would have(more than 2 @).I have done away with the countChar method.
Incase you want to count how many times "@" appears,you need to modify countChar method
