Write a program to input ten numbers from keyboard and find the sum of all even numbers and odd numbers
Here’s a Java program that inputs ten numbers from the keyboard and finds the sum of all even and odd numbers:
import java.util.Scanner;
public class SumEvenOdd {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int[] numbers = new int[10];
int evenSum = 0, oddSum = 0;
// Input 10 numbers from the user
System.out.println("Enter 10 numbers: ");
for (int i = 0; i < 10; i++) {
System.out.print("Number " + (i + 1) + ": ");
numbers[i] = scanner.nextInt();
}
// Calculate the sum of even and odd numbers
for (int i = 0; i < 10; i++) {
if (numbers[i] % 2 == 0) {
evenSum += numbers[i];
} else {
oddSum += numbers[i];
}
}
// Output the results
System.out.println("Sum of even numbers: " + evenSum);
System.out.println("Sum of odd numbers: " + oddSum);
scanner.close();
}
}
Explanation:
- Scanner Initialization: A
Scannerobject is created to take input from the user. - Array Declaration: An array
numbersof size 10 is declared to store the user inputs. - Input Loop: A
forloop runs 10 times to take input from the user and store it in the array. - Sum Calculation Loop: Another
forloop iterates through the array to calculate the sums of even and odd numbers. - Condition Check: Inside the second loop, each number is checked to see if it is even or odd using the modulus operator (
%). Ifnumbers[i] % 2 == 0, the number is even; otherwise, it is odd. - Sum Update: Based on the condition check, the number is added to
evenSumoroddSum. - Output: Finally, the sums of even and odd numbers are printed.
Sample Output:
Enter 10 numbers:
Number 1: 12
Number 2: 7
Number 3: 5
Number 4: 10
Number 5: 2
Number 6: 3
Number 7: 8
Number 8: 15
Number 9: 6
Number 10: 1
Sum of even numbers: 38
Sum of odd numbers: 31
Running the Program:
To compile and run this Java program, follow these steps:
- Save the program in a file named
SumEvenOdd.java. - Open a terminal or command prompt and navigate to the directory containing the file.
- Compile the program using the
javaccompiler:
javac SumEvenOdd.java
Run the compiled program using the java command:
java SumEvenOdd
This will prompt you to enter ten numbers and then display the sum of even and odd numbers
