java
Parameters: int start, int end
start and end points of the range (inclusive)
Returns: Returns the sum of squares of integers in the range
The function uses a loop to iterate over a range of numbers, squares each number and totals all results. It is a great practice task for Java beginners learning about loops, mathematical functions and returns.
Hello there, programmer! Welcome to this programming journey. In the following steps, we will unveil a simple task, writing a Java function named 'find-sum-squares-range'. It will calculate the sum of squares within a range. By doing so, we'll explore key concepts of Java programming. Sit back, relax, and get ready to dive deep into coding. No jargon, no complications - just pure, straightforward coding. Let's get started!
The first thing we need to do is setup our basic Java structure. This includes our class definition, and the main function where our code will be executed from.
public class Main {
public static void main(String[] args) {
}
}
The next step is to define a function that will calculate the sum of squares between a specified range. This function will take two integer parameters to define the range.
public class Main {
public static void main(String[] args) {
}
public static int findSumSquaresRange(int start, int end) {
}
}
We then need to setup a loop that will iterate over the range, and calculate the square of each number during each iteration.
public class Main {
public static void main(String[] args) {
}
public static int findSumSquaresRange(int start, int end) {
int sum = 0;
for(int i = start; i <= end; i++) {
sum += i * i;
}
return sum;
}
}
Finally, we will call this function from the main function, and print out the result.
public class Main {
public static void main(String[] args) {
system.out.println(findSumSquaresRange(1, 3));
}
public static int findSumSquaresRange(int start, int end) {
int sum = 0;
for(int i = start; i <= end; i++) {
sum += i * i;
}
return sum;
}
}
With the steps above, we can calculate the sum of squares for a range of numbers in java. The range is inclusive. So in our main function, where we called findSumSquaresRange(1, 3), it will calculate the sum of squares for numbers 1, 2, and 3. Should you want a different range, all you have to do is to replace the parameters in the findSumSquaresRange function call.
The mathematical principle used is the sum of squares formula. This is where each number in a range is squared and the results are all added together. In mathematical notation, where `n` is each number in the range, the formula is `total = Σ (n^2)`.
