Java Subtract Function Guide

In Java, the subtract function is typically used for performing subtraction operations on numbers. It takes two numbers as input and returns their difference. For example:

public static int subtract(int a, int b) {
    return a - b;
}

public static void main(String[] args) {
    int result = subtract(10, 5);
    System.out.println(result); // 输出结果为：5
}

The code above defines a subtract function that takes two integer parameters, a and b, and then returns their difference. In the main function, the subtract function is called and the result is printed, which is 5, the result of subtracting 5 from 10.
