import java.util.Scanner;


class App {


	public static void main(String[] args) {
		java.util.Locale.setDefault(new java.util.Locale("en-US", "en-US"));
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Ente a String: ");
		String[] numbersStr = keyBoard.nextLine().split(" ");
		int intValuesCounter = 0;
		double decimalValuesCounter = 0;
		double sum = 0;
		for (int i = 0; i < numbersStr.length; i++) {
			if (numbersStr[i].contains(".")) {
				try {
					double doubleValue = Double.parseDouble(numbersStr[i]);
					sum += doubleValue;
					System.out.println("Double value: " + doubleValue);
					decimalValuesCounter++;
				} catch (Exception e) {
					System.out.println("Wrong value");
				}
			} else {
				try {
					int intValue = Integer.parseInt(numbersStr[i]);
					sum += intValue;
					System.out.println("Integer value: " + intValue);
					intValuesCounter++;
				} catch (Exception e) {
					System.out.println("Wrong value");
				}
			}
		}
		System.out.println(intValuesCounter + " int values were found");
		System.out.println(decimalValuesCounter + " decimal values were found");
		System.out.println("Sum: " + sum);


		keyBoard.close();
	}
