When use method overloading and when use method overriding concept??

Question

I totally confused to use that both overloading and overriding in java code

Answer 1

//C# examples:

// overriding
class base {
public virtual void methodName()
}

class child : base {
public override void methodName()
}

//overload
class whatever {
public void methodName(int parameter) { do something ;}

public void methodName(string parameter)
{ do something else; }
}
