Practical Case

Use CodeChef online compiler to write a simple Java function to calculate the sum of two numbers.

import java.util.Scanner;

public class SumOfNumbers {

    public static void main(String[] args) {
        // 输入两个数字
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter first number: ");
        int num1 = scanner.nextInt();
        System.out.println("Enter second number: ");
        int num2 = scanner.nextInt();

        // 创建一个函数来计算和
        int sum = calculateSum(num1, num2);

        // 打印结果
        System.out.println("Sum of " + num1 + " and " + num2 + " is: " + sum);
    }

    // 创建一个函数来计算两个数的和
    public static int calculateSum(int num1, int num2) {
        return num1 + num2;
    }
}
