Input Mismatch Error in Java

Hi, I was creating a calculator program, which take the numerator, denominator and the operator as the input and should display the correct output, but I amhaving an Input Mismatch Error. I have searched online but nothing solved the issue. Would anyone be able to solve the issue? Here is the code bit: https://sololearn.com/compiler-playground/c96n8tjgILRo/?ref=app

Danish Zubair You can also try this input method int numerator = sc.nextInt(); int denominator = sc.nextInt(); String operator = sc.next();

You first have to enter the numbers, then the operator – that's how you defined it in your code. Also, find out about how to compare strings in Java. Your switch statement won't work that way.

Try this int numerator = sc.nextInt(); int denominator = sc.nextInt(); sc.nextLine(); String operator = sc.nextLine(); The point is that the "nextInt" method scans the string up to the number, i.e. you can enter 2 numbers in one line, and each method will recognize it, but will not go to the next line

Danish Zubair Strange, everything works for me What input did you make? I made the following input (This is if you added that line of code that I mentioned above) number number operator

Buterbrod:) yeah found the solution, I converted from String type to character type the variable 'operator' and wrote 'sc.next()' and it worked. Thank you so much for helping me.
