Method overloading simply means various methods having same name.
If the methods have the same name, how can Java know which method you mean? There’s a simple rule: Each overloaded method must take a unique list of argument types.
If you think about this for a second, it makes sense. How else could a programmer tell the difference between two methods that have the same name.
Even differences in the ordering of arguments are sufficient to distinguish two methods, although you don’t want to take this approach because it makes the code hard to maintain.
