Here is one answer i gave to another person about static variable inside classes:

One example would be if you want to store a value across several instances. Here is an example:

class Person {
    public static int numberOfPeople = 0;
    private String name;

    {
        numberOfPeople++;
    }

    Person() {
        this.name = "Default Name";
    }

    Person(String name) {
        this.name = name;
    }

}


class Test {
    public static void main(String[] args) {
        Person p1 = new Person("Mark");
        Person p2 = new Person("Joe");
        Person p3 = new Person();

        //This will print 3
        System.out.println(Person.numberOfPeople);
    }
}

Simply you can put static keyword is something which could be accessed without instantiating. Static methods could be called without making a object or instantiating you can access the static method directly hope this helps you.
