java
Parameters: int a, int b
Two integers, 'a' represents the minuend and 'b' the subtrahend.
Returns: Returns the result of subtracting the second number from the first.
This is a simple Java function that accepts two numbers as input and returns their difference as the output. It's a great starting point for beginners in programming.
Hello, Programmer! Welcome to this blog post. The following steps would guide you on how to program a function to subtract two numbers in Java. This simple yet effective concept forms the basis of more complex programs. Don't worry, we'll keep it straight and jargon-free. Let's dive into it!
Start by creating a new Java class. In Java, every application must contain a main method that calls all the other methods. Let's call our class SubtractTwoNumbers and create a main method within it.
public class SubtractTwoNumbers {
public static void main(String[] args) {
}
}
Next, inside the main method, declare two integer variables that will hold the values to be subtracted. We will call these number1 and number2 and we will hard code their values for simplicity.
public static void main(String[] args) {
int number1 = 10;
int number2 = 5;
}
Now, we will subtract number2 from number1 and store the result in a new variable called result.
public static void main(String[] args) {
int number1 = 10;
int number2 = 5;
int result = number1 - number2;
}
Finally, we will print the result to the console using the System.out.println() method.
public static void main(String[] args) {
int number1 = 10;
int number2 = 5;
int result = number1 - number2;
System.out.println('The result is: ' + result);
}
So, this is how we can subtract two numbers in Java. Here's the complete code.
public class SubtractTwoNumbers {
public static void main(String[] args) {
int number1 = 10;
int number2 = 5;
int result = number1 - number2;
System.out.println('The result is: ' + result);
}
}
Remember, the values of number1 and number2 are hardcoded for demonstration purposes. In a real-world application, you might take input from the user or from some other part of your program.
The fundamental mathematical principle here is subtraction which is one of the basic arithmetic operations. In mathematics, subtraction represents the operation of removing objects from a collection. Here, we're removing the second number from the first as `result = firstNumber - secondNumber`.
