You have many syntax errors. Inside your public class MathExploreToy and then you write
What is this? If you are trying to make a constructor this is not the appropriate way. Check again your curly braces and try fixing your errors and ask a specific question if you have. I suggest you reading the java tutorials for defining methods.public class MathExploreToy(){ }
And please use the highlight tags for better readability.

okay thanks for your comments its really good for my learning
You have it in the right place. java.io is not a function (method in java), it's a package. You can't import a method, you import packages (in the beginning of your code, before you declare your class). Here is java.io. If you are a begginner you should familiarize yourself with the Java API. And you should also google every question you have, you will find answers to almost everything.
