Java Program to demonstrate use of static keyword
Write a Java program to demonstrate use of "static" keyword.
Source Code
public class Circle {
public static int numCircle = 0;
double x,y,r;
public Circle(double x, double y, double r) {
this.x = x;
this.y = y;
this.r = r;
numCircle++;
}
public static void main(String[] args) {
Circle c1 = new Circle(1.0,3.0,2.5);
Circle c2 = new Circle(1.0,3.0,2.5);
Circle c3 = new Circle(1.0,3.0,2.5);
System.out.println("x = " + c1.x);
System.out.println("y = " + c1.y);
System.out.println("r = " + c1.r);
System.out.println("numCircle = " + numCircle);
}
}
Output
x = 1.0
y = 3.0
r = 2.5
numCircle = 3
