Printing a Special Series in Java Using a For Loop

In this article, we will explore how to print a special series of numbers in Java by utilizing a for loop. The series goes as follows: 13 31 17 71 37 73... 97. We'll provide a detailed explanation of the logic and write the necessary Java code to achieve this.

Main Concept

The primary concept behind generating this series involves reversing the digits of each number. Let's break down the process step-by-step.

The Series Pattern

First, let's take a closer look at the series: 13 31 17 71 37 73... 97. We can see that the numbers are formed by taking a two-digit number and producing a new number by swapping its digits. For example, starting from 13, we reverse it to get 31. Continuing this pattern leads to the remaining series.

The Code Implementation

To implement this in Java, we will use a for loop. The loop will iterate through the numbers from 13 to 97. For each number, we will first determine its digits by dividing and using the modulus operator. Then, we will reverse the digits and print the result.

Step-by-Step Explanation

Initialize the loop to iterate from 13 to 97 using the for loop.

Within the loop, extract the quotient and the remainder:

quotient i / 10

remainder i % 10

Calculate the reversed number by placing the remainder in the tens place and the quotient in the ones place:

reversed remainder * 10 quotient

Print the reversed number:

(reversed);

Java Code Implementation

Here is the complete code implementation in Java:

public class ReverseNumberSeries {
    public static void main(String[] args) {
        for (int i  13; i  97; i  ) {
            int quotient  i / 10;
            int remainder  i % 10;
            int reversed  remainder * 10   quotient;
            (reversed);
        }
    }
}

Code Explanation

quotient i / 10: This divides the number by 10 to get the first (tens) digit.

remainder i % 10: This gives the second (ones) digit of the number when using the modulus operator.

reversed remainder * 10 quotient: By assigning the remainder to the tens place and the quotient to the ones place, we effectively reverse the digits.

(reversed);: Prints the reversed number to the console.

Conclusion

Using a for loop in Java, we can easily generate and print a series of numbers where the digits of each number are reversed. This article and the provided code demonstrate the process step-by-step, ensuring a clear and easily understandable implementation. Understanding and mastering such concepts can significantly improve your programming skills in Java.
