please who can help, i don't understand why when i called the convertEurToUsd method twice using convertEurToUsd(1,2.2) convertEurToUsd(2,2.2) and displayed it twice using( System.out.println(convertEurToUsd(1,2.2)); ( System.out.println(convertEurToUsd(2,2.2)); my second requirement was not met until i commented out the call of the method.
