java - How to access parent class integer variable in child class? -
this question has answer here:
i trying access int a= 10 variable in child class getting error:
cannot make static reference non-static field freshjuice.a
following code.
class freshjuice { enum freshjuicesize{small,medium,large}; freshjuicesize size; int = 10; } public class index extends freshjuice { enum programminglanguage{php,java,dotnet,html}; public static void main(string[] args) { // todo auto-generated method stub system.out.println(freshjuice.freshjuicesize.small); system.out.println(programminglanguage.php); system.out.println(freshjuice.a); //getting error in line } }
i want directly access int variable of freshjuice class in child class. how can achieve target?
first create instance of freshjuice class:
freshjuice fj = new freshjuice();
now can access variable a
.
but if set variable private int a=10;
can't access still. that's why practice use getter , setter methods access private variables.
