You will be using the “println” method often, so you will want to make sure you can do it quickly and without needing to look up how to type it in correctly. println (' This BMI Calculator may overestimate fat in muscular individuals and underestimate body fat in older people. Contribute to eddiemack/BlueJ-Projects development by creating an account on GitHub. By working backwards, you can start to recognize the types of things that cause common errors. Compilation of BlueJ projects from Programming 2. The error messages are hard to understand at first, but you need to start learning to use them to find errors in your code. Spell “System” wrong or forget to capitalize it.Move your print command to the wrong part of the program.

Run the code each time and read the compiler’s error messages.

“Break” your code in a few different ways to see what sort of error message you get.For example, make it say “This is my first program.” and then a new line to print “Learning to program takes a lot of work, but it is worth it!” (each of these command ends with a semicolon ) Add more code so your program will print multiple statements when you run it.Lines of code between curly braces make up a code block. You can delete everything between the first and last curly bracket, then type the part that says “public static void main(). You can clean this up by deleting text so it just looks like this: public class FirstProgram

Here we discuss the Introduction to Calculator in Java and its different Methods and Examples and Code Implementation.(download and install BlueJ if running on your own computer)įrom the Project menu, click New Project.Ĭhoose a folder to save this project and give it a reasonable name.Ĭlick the icon that appears, and you will see some pre-written code. This calculator in Java can be done in 2 ways by using a switch case statement and by using swing API. package Calculator is used to calculating operations like addition, subtraction, division, multiplication, modulus, and power. Step4: Add all these components to the Screen. Step3: Write an Action listener for all the buttons. Step2: Creating buttons for numbers from 0-9 and character buttons like +, -, *, *, % etc. Step1: Creating a class and extends it from JFrame, ActionerListener. } while (result_operation_output != 'Q') (firstNumber + " " + operator + " " + secondNumber + " is : " + result_operation_output) ("Please enter specified operator only") Lets see the code of creating calculator. Result_operation_output = Math.pow(firstNumber, secondNumber) Calculator in Java with Source Code: We can develop calculator in java with the help of AWT/Swing with event handling. Result_operation_output = firstNumber % secondNumber However, I want to find an alternative to if then statements that are NOT conditionals, loops, or arrays. Result_operation_output = firstNumber / secondNumber This is a program I typed up for a project pertaining to GPA calculation. Result_operation_output = firstNumber * secondNumber Result_operation_output = firstNumber - secondNumber Result_operation_output = firstNumber + secondNumber ("Enter an operators like (+, -, *, /, %, ^) only:\n ") Ĭhar operator = scannerObject.next().charAt(0) SecondNumber = scannerObject.nextDouble() ("Enter your first number:\n") įirstNumber = scannerObject.nextDouble() Scanner scannerObject = new Scanner(System.in) Creating scanner for object for allow input } Example #1 – Switch Case Calculator Functionality Step 3: Based on character operation performed like addition, subtraction, multiplication, division, modulus (finds remainder) and power of the number. Step 2: Within the switch case, we have implemented logic for each character. Step 1: User enters the character for which operation wants to perform like “+”, “-”, “*”, “/”, “%”, “^” etc. Algorithm: Start Declare three methods of the same name but with a different number of arguments or with different data types. In this program, we will see how to find the area of the square, rectangle, and circle using Method Overloading.
