Description: The program prompts the user to enter three numbers and invokes the method: public static void displayIncreasingNumbers(int num1, double num2, long num3) to display them in increasing order.
Below is my code:
package threeincreasingnumbers;
import java.util.Scanner;
public class Threeincreasingnumbers {
public static void main(String[] args) {
// Create Scanner
Scanner scan = new Scanner(System.in);
// Prompt the user to enter three numbers
System.out.print("Enter three numbers: ");
int num1 = scan.nextInt();
double num2 = scan.nextDouble();
long num3 = scan.nextLong();
// Display numbers in increasing order
displayIncreasingNumbers(num1, num2, num3);
}
public static void displayIncreasingNumbers(int num1, double num2, long num3) {
double temp;
if (num2 < num1="" &&="" num2=""><>
temp = num1;
num1 = (int) (double) num2;
num2 = temp;
}
else if (num3 < num1="" &&="" num3="">< num2)="">
temp = num1;
num1 = (int) num3;
num3 = (long) temp;
}
if (num3 < num2)="">
temp = num2;
num2 = num3;
num3 = (long) temp;
}
// Display result
System.out.println(num1 + " " + num2 + " " + num3);
}
}
But I get the error when run: Exception in thread "main" java.util.InputMismatchException
at java.util.Scanner.throwFor(Scanner.java:864)
at java.util.Scanner.next(Scanner.java:1485)
at java.util.Scanner.nextInt(Scanner.java:2117)
at java.util.Scanner.nextInt(Scanner.java:2076)
at threeincreasingnumbers.Threeincreasingnumbers.main(Threeincreasingnumbers.java:21)
I assume there is a problem comparing int, double and long numbers. How can I solve this problem?
