Printing Powered Integers in One Line in Java

When coding in Java, we often encounter scenarios where we need to display results in a specific format. One such scenario arises when working with powered integers. In this guide, we’ll discuss the problem of generating and printing powered integers in a single line, as well as the solution to achieve that.

The Problem

Imagine you want to create a function that generates integers based on a user input parameter n. The function should calculate the sum of integers raised to the power of n. For instance, calling totalCue(3) should compute:

However, you might end up getting the output in a cluttered format like this:

The challenge lies in printing the results in a clean, readable line as follows:

The Solution

To rectify the output formatting in the Java code, we will implement a few changes in the System.out.print() method used within the integer calculations. Here’s a step-by-step breakdown of how to modify your code:

Revised Code Snippet

Create a Temporary Variable: This avoids recalculating the power for each integer, making your code more efficient.

Control the Formatting: Use a string variable to append a "+ " before terms after the first term, ensuring proper display.

Here's the Implemented Code

Code Explanation

String plus: We initialize an empty string, which adds the "+ " sign before subsequent terms, creating a clean format.

term Variable: This stores the powered integer, avoiding repetitive calculations and improving performance.

System.out.print(plus + term): This prints the current term prefixed by the string plus. Initially, plus is empty, so the first term is printed without a "+ " sign.

Final Output

When you run the revised code, the output will be neatly formatted as desired:

Conclusion

By making these simple adjustments to your Java code, you can ensure that your powered integers are displayed in a clear and readable format. This not only improves the aesthetics of your output but also aligns with best programming practices by reducing redundancy in calculations.

Happy coding, and may your outputs always be tidy! If you have any further questions or need assistance with your Java projects, feel free to reach out.
