import java.util.Scanner; public class as{ public static float sum (float x,float y ){ return x + y; } public static void main (String[]args ){ Scanner sc=new Scanner (System.in); float input =sc.nextFloat(); float output =sc.nextFloat(); char op = sc.next().charAt(0); switch(op){ case '+': System.out.println(sum(input,output)); break; } } }

Maybe try a different compiler? The problem seems to be with ideone.com The program runs fine. I'd suggest downloading IntelliJ, Eclipse, or Visual Studio Code Java and installing a JDK on your machine (Java 8 or 11 should be fine) to run your programs on your local machine if possible. 5.5 3.3 + 8.8 Process finished with exit code 0 2.3 4.7 - Process finished with exit code 0 1 2 + 3.0 Process finished with exit code 0 (following is expected behavior) 6 j 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.nextFloat(Scanner.java:2496) at as.main(as.java:12) Process finished with exit code 1

Make the name of main class similar for name of file (file. Java) If you save the all class in one folder, write the name of folder by english
