Answer:
The code for this class is shown in the explanation section
Explanation:
public class Circle {
private double radius;
private double diameter;
private double area;
public Circle(double radius, double diameter, double area) {
this.radius = 1;
this.diameter = diameter;
this.area = area;
}
public void setRadius(double radius) {
this.radius = radius;
diameter = radius*2;
area= Math.PI*(radius*radius);
}
public double getRadius() {
return radius;
}
}
Answer:
*jspService()
Explanation:
These are the steps in JSP life cycle.
1. Conversion JSP page to Servlet
.
2.Compilation of JSP page(test.java)
3.Class is loaded (test.java to test.class)
4.Instantiation (Object is created)
5.Initialization (jspInit() method is only called once at the time of servlet generation )
6.Request processing(_jspService() method is used for serving requests by JSP)
7.JSP Cleanup (jspDestroy() method is used for removing JSP from use)
There is no *jspService() method in the JSP life cycle.
Answer:
Following are the code in java language
abstract interface PointingDevice // interface PointingDevice,
{
// abstract method getXCoord()
public abstract int getXCoord();
// abstract method getYCoord()
public abstract int getYCoord();
// abstract method attentionRequired()
public abstract boolean attentionRequired();
// abstract method setResolution( )
public abstract double setResolution(double a);
}
Explanation:
In this code we have declared a abstract interface "PointingDevice" which contains the four abstract method getXCoord of type int , getYCoord() of type int , attentionRequired() of type boolean and setResolution() of type double .
These method have only declaration not definition any interface or class which inherit the inteface PointingDevice must define all these four method otherwise it also be abstract .
