- Java - Encapsulation A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0, 0), the bottom right corner of the console is point (MAX, MAX) and given two points (all “x” and “y” coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class Point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the samplearea() - computes and returns the area of a given rectangleperimeter() - computes and returns the perimeter of a given rectanglecenterPoint() - computes and returns the center point…ELP IN JAVA CODE PLEASE! Creating a JAVA program that should implement a method that verifies whether a given 4 x 4 square (containing 16 values) is a Magic Square with a given magicValue. Also, adding code to generate values for a magic square based on a magicValue and execute as the picture is shown below. Make sure the old magic square is erased when the new magic square is executed.Return the Remainder from Two Numbers Language: Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) 1 remainder (3, 4) 3 remainder (-9, 45) -9 remainder(5, 5) 0

A Simple Game by CodeChum Admin You probably are fond of games. This quiz though is not that complicated. You are simply going to work with a point on a screen, and a circle on a screen as well. And let's consider them as the characters in the game. We are going to call both of these characters as Movable objects. Objects are said to be Movable if they can be moved around the screen. The following simple movements are allowed: public void moveLeft(); // moves the x to the left by 1 unit public void moveRight(); // moves the x to the right by 1 unit public void moveUp(); // moves the y 1 unit upward public void moveDown(); // moves the y 1 unit downward public void display(); // prints all the info about a Movable Both Point and Circle characters are Movable. The Point has an x coordinate and a y coordinate. The Circle has a Point (representing its center) and a radius (for our purpose this is an int). The attributes may all be set to public. It goes…

Computes and stores the rectangle area, perimeter and diagonal. printRectangle: Prints the width, height, area, perimeter and diagonal of the rectangle with labels. All values are printed with a maximum of 2 digits after the decimal. Extra Credit (+5): Include a visual representation of the rectangle: ##### #3 # #### Extra Credit (+2): Visual representation works with length of 1 for height and/or width. changeWidth: Changes the width…JAVA Programming: After Elon Musk decided to make a new business idea. He found a social network called "Friends.com". It has currently N registered users. Likewise in any social network many users can be friends. Elon Musk wants the world to be as super connected as possible, so he has this new way to suggest friendship to some pairs of users. He suggests user u to have a friendship with user v if they are not friends yet and there is a user w who is friends of both of them. Note that u, v and w are different users. Elon Musk is too busy with SpaceX these days, so he hired you to develop a JAVA program to count out how many friendship suggestions he has to send over his social network "Friends.com". Sample Input: 3 0111 1000 1000 Sample Output: 2Java What is the scope of the variable tempNum? (Type your answer as two line numbers with a comma between. For example if a variable's scope would go from lines 5 to 10, you would type 5, 10.)
