Basic calculator using switch

Tuesday, October 31, 2023 Difficulty: Easy


Write a Java program that functions as a basic calculator. This program allows the user to perform simple mathematical operations with two numbers. The user will input two numbers and then select an operation (addition (+), subtraction (-), multiplication (x or *), or division (/)) using a switch block. The program will perform the selected operation and display the result on the screen.

We add complexity by allowing decimal operations instead of integers. If the user inputs a decimal number or if the operation results in a decimal number, the program should display the result with two decimal places.

Additionally, if the user attempts to divide by zero, the program should indicate "Division by zero not allowed."

If the operation symbol is different from the allowed operators (+, -, x, /), the program will indicate "Character not recognized."




6.5 * 2 = 13.00
