![]() While passing the Scanner to each function separately would allow your methods to work as intended, the first option is slightly more readable. Initialized within the class, but outside of any methods Scanner keyboard = new Scanner( System.in ) Since your program is broken up into several methods, the data inside each method is local unless you store it inside the class itself.įor example, your helper functions for getLength() and getWidth() wouldn't be able to access your keyboard Scanner unless you declared it outside of the main method, as such: import What am I screwing up on and how would I go about fixing it? I am a beginner in programming so please bear with me :D. ![]() Public static void displayData(double length, double width, double area) Scanner keyboard = new Scanner(System.in) Īrea = getArea(double length, double width) I don't know how to complete this code because right now what I have is this: import ![]() displayArea – This method should accept the rectangle’s length, width, and area as arguments, and display them in an appropriate message to the screen.The area is calculated by multiplying the length by width. getArea – This method should accept the rectangle’s length and width as arguments, and return the rectangle’s area.getWidth – This method should ask the user to enter the rectangle’s width, and then return that value as a double.getLength – This method should ask the user to enter the rectangle’s length, and then return that value as a double.The program should call the following methods: Write a program that asks the user to enter the width and length of a rectangle, and then display the rectangle’s area. Good programmer and crack the java software developer interview with ease.The question that I am really stuck on is this: Public static void calculate(int sideLength)Įxplore complete java concepts from the Java programming examples and get ready to become a In this method, first the side length of square will be taken by the user and this value will be passed to the user defined method calculate() where the logic to find area and perimeter is implemented. Perimeter of Square = 16 Method-3: Java Program to Find Area and Perimeter of Square By Using User Defined Method ("Enter length of any side of square : ") taking the length of any side of square from the user Scanner class object created fro taking user input Method-1 and Method-2 is same the difference is only in assigning side length value of square. In this method, the side length of square will be taken as user input and then the area and perimeter of square will be calculated as per method-1. Perimeter of Square = 20 Method-2: Java Program to Find Area and Perimeter of Square By Using Dynamic Values length of each side of square is given Which will be used to calculate the area and perimeter of square by using the formula. In this method, the side length of square is already declared in the program and stored by the variable sideLength. Method-1: Java Program to Find Area and Perimeter of Square By Using Static Values Then area of square => perimeter = 4*sideĭon’t miss the chance of Java programs examples with output pdf free download as it is very essential for all beginners to experienced programmers for cracking the interviews. => area = 16 Example- To find Perimeter of Square ![]() ![]()
