Your job is to go through and fix them. You will need to make edits in both files to get them working correctly, but once complete, your output should match the output below.

<u>Answer:</u>

CIRCLE.JAVA

public class Circle {

  <em>private</em><em> </em>double radius;

  <em>public</em> Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 <em>public </em>double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 <em>public </em> double getPerimeter() {

   return Math.PI*getDiameter();

 }

 <em>public</em> String toString() {

    return "Circle with a radius of " + radius;

 }

}

CIRCLE TESTER.JAVA

public class CircleTester {

 public static void main(String[] args) {

    Circle circ = new Circle(10);

    circ.radius = 5;

    System.out.println(circ);

    System.out.println("The diameter is " + circ.getDiameter());

    System.out.println("The perimeter is " + circ.getPerimeter())

 }

}

<u>Explanation:</u>

public class Circle {

  //This could be made private or public.

  //Making it private is better

  <em>private</em><em> </em>double radius;

  //This is a constructor. It should be made public

  //since it would most likely be used in another class

  //to create an object of this class.

  //Making it private means no other external class can create

  //an object of this class.

  //Since the tester class (CIRCLETESTER.java), as shown on line 3,

  // needs to create

  //an object of this class, this should be made public

  <em>public</em> Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 //This should be made public since it will be

// used in another class (CIRCLETESTER.java in this case)

 <em>public </em>double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 //This should be made public since it will be

 //used in another class (CIRCLETESTER.java)

 <em>public </em> double getPerimeter() {

   return Math.PI*getDiameter();

 }

 //The toString() method is the string representation

 //of an object and is called when there is an attempt to

 //print the object. It should be made public since it will

 //be used in another class (CIRCLETESTER.java)

 <em>public</em> String toString() {

    return "Circle with a radius of " + radius;

 }

}

CIRCLE TESTER.JAVA

public class CircleTester {

 public static void main(String[] args) {

    Circle circ = new Circle(10);

    circ.radius = 5;

    System.out.println(circ);

    System.out.println("The diameter is " + circ.getDiameter());

    System.out.println("The perimeter is " + circ.getPerimeter())

 }

}

How are static variables and methods created in Java? What happens if a non-static method of a class tries to access a static va
9966 [12]

Answer:

Static variables are the variables decaraed with keyword static, static variables must be deacraled inside the class body, means we can not declare a static variable inside a method or consttructor, static variable belongs to class, for a class only one copy is created for static variable and used by all the objects/instances.

Static variable can access with class name like

X.i

Static method are the methods defined with static keyword, static method are also part of a class, we can access static meethod using class name like

X.printI()  

Explanation:

class X

{

//to create a static variable we need use static keyword with variable name like

public static int i;

// to create a static method we need to use static keyword while defining a method like

public static void printHello() {

 System.out.println("Hello");

}

/*

 * A non static method can access static variable of a class there is no issue

 * with that we can use a static variable in a non static method like

 */

public void printI() {

 System.out.println(i);

}

/*

 * As long as the class exist in JVM static variables will be there, as static

 * variable belong to class not with the instance,

 * it does not matters if there are instance exist or not

 */

}

How can the connection to salesforce be restricted only to the employee portal server? Universal containers (UC) uses a legacy E
Ad libitum [116K]

Answer

To restrict the connection only to the employee portal server, the IP address of the application should be added into the list of Trusted IP's.

Explanation:

Trusted IP's are the IP's that are used to identify the users that can be verified easily. Those users whose IP's are not listed in the trusted IP list needs to verify their identity by sending them login code on each transaction.

<em>In above mentioned case, We need to enlist the IP address of employee portal list in trusted IP list to ensure the restriction of login to employee only.</em>
