Difference between public static and private static variables

Question

class Employee{
 // salary  variable is a private static variable
private static double salary;

// DEPARTMENT is a constant
 public static final String DEPARTMENT =         


        

Answer 1

public static - can be accessed from within the class as well as outside the class.

private static - can be access from within the class only.

Static's are considered to be anti-OO in OOPS.

class Dog
{
    public static string X;
    private static string y;
}

y can be accessed only from inside Dog via either Dog.y or just y. X can be accessed anywhere via Dog.X or, if you're either in the class or using using static Dog as a header, just X.
