Java setters and getters

Question

I have been struggling with setters and getters in java for quite a long time now.

For instance, if I want to write a class with some information as name, sex, age

Answer 1

You create an object by instantiating the constructor as follows

Personinfo pi = new Personinfo("Anna", "female", "17");

You can then call methods upon that object as follows

pi.setName("Alan");

or

pi.getName();
