It would be better if you code post the code. Use the code tags when you post and it will stay indented.ProPatto16 said:Not sure why it's centred that thread, hope it's still readable

To call a method in Java, you need to use the method name followed by parentheses. If the method requires any parameters, they should be placed inside the parentheses. For example, if you have a method called calculateSum that takes two integers as parameters, you would call it like this: calculateSum(5, 10).
Yes, you can have multiple methods with the same name in Java as long as they have different parameter lists. This is called method overloading. Java will be able to differentiate between the methods based on the number, type, and order of the parameters.
You can use the return keyword to specify the value that the method should return. The return type of the method must match the type of the value being returned. For example, if you want to return an integer, the method should have a return type of int and you should use the return keyword followed by the integer value that you want to return.
Yes, a method can call itself in Java. This is known as recursion and it can be a useful technique for solving certain types of problems. However, it is important to make sure that the recursion has a base case to prevent an infinite loop.
