I wrote a small calculator program, and when I try to set float numbers it gives me the following crash log:
**Exception in thread "main" java.util.InputMismatchException at java.base/java.util.Scanner.throwFor(Scanner.java:939) at java.base/java.util.Scanner.next(Scanner.java:1594) at java.base/java.util.Scanner.nextInt(Scanner.java:2258) at java.base/java.util.Scanner.nextInt(Scanner.java:2212) at Main.main(Main.java:9)Process finished with exit code 1**My code is :
import java.util.Scanner;public class Main { public static void main(String[] args) { System.out.println("Welcome to the calculator program: " ); System.out.println( "\n Please enter 2 numbers :"); Scanner scanner = new Scanner(System.in); float number1 = scanner.nextInt(); float number2 = scanner.nextInt(); float sumOfNumbers = number1 + number2; float subtractionOfNumbers = number1 - number2; float multiplicationOfNumbers = number1 * number2; float divisionOfNumbers = number1 / number2; System.out.println("Please choose what operation do you want - (+)/(-)/(*)/(/): "); System.out.println(" 1 = + / 2 = - / 3 = * / 4 = /"); int operation = scanner.nextInt(); switch (operation) { case 1: System.out.println("The sum of " +number1+" and " +number2 +" is " +sumOfNumbers); break; case 2: System.out.println("The subtraction of " +number1+" and " +number2 +" is " +subtractionOfNumbers); break; case 3: System.out.println("The multiplication of " +number1+" and " +number2 +" is " +multiplicationOfNumbers); break; case 4: System.out.println("The division of " +number1+" and " +number2 +" is " +divisionOfNumbers); break; } }}Why I'm getting crash when I'm trying to set float numbers?
