Reference static field after declaration in Java
The static field variable is a class level variable and it belongs to the class not the class object.
So the static field variable is common to all the class objects i.e. a single copy of the static field variable is shared among all the class objects.
A program that demonstrates referencing the static field variable after declaration is given as follows:
Example
public class Demo {
static int a = 7;
static int b = a + 5;
public static void main(String[] args) {
System.out.println("a = " + a);
System.out.println("b = " + b);
}
}Output
a = 7 b = 12
Now let us understand the above program.
The class Demo contains static variables a and b. The method main() prints the values of a and b. A code snippet which demonstrates this is as follows:
static int a = 7;
static int b = a + 5;
public static void main(String[] args) {
System.out.println("a = " + a);
System.out.println("b = " + b);
}
