Sorting Strings According to Scores: A Simple Guide to Descending Order in Java

Understanding the Problem

You've got two arrays in your Java program: one for name and another for score. The goal is to sort the score array in descending order while correctly associating the names from the name array. The challenge arises because if you only sort the score, the names will not match the sorted scores, leading to incorrect outputs.

Example Input

Here’s how your input data looks:

Desired Output

The expected output, after sorting the names according to their scores in descending order, should be:

Solutions to Your Problem

To tackle this issue effectively, there are two potential solutions you can implement:

Solution 1: Using Objects

Create a Custom Class: Define a class that can hold both the name and score. Let’s call it ScoreEntry.

Store in an Array: Instead of using two separate arrays, create an array of ScoreEntry objects.

Sort Objects: Implement a sorting method using a simple bubble sort or any other algorithm that sorts based on the score attribute.

Display Sorted Output: After sorting, iterate through your array and print the names and scores.

Solution 2: Adjusting Indices for Names

Two-Array Sort with Index Adjustment: If you prefer not to use objects, you can sort the score array but also maintain an index array that reflects the original indices of the names.

Conclusion

Sorting arrays doesn't have to be daunting. By restructuring your data into objects or carefully adjusting indices, you can maintain accurate data integrity when sorting. Choose the solution that best fits your needs and don't hesitate to experiment with both approaches. Good luck with your assignment!
