Refactoring the files to be in correctly nested packages

[varada610]

• I have read CONTRIBUTING.md.
• This pull request is all my own work -- I have not plagiarized it.
• All filenames are in PascalCase.
• All functions and variable names follow Java naming conventions.
• All new algorithms have a URL in their comments that points to Wikipedia or other similar explanations.
• All new code is formatted with clang-format -i --style=file path/to/your/file.java

Looks good, thanks!

Please check why build and linter fail, you probably need to fix formatting to fix them

[siriak]

Or try updating with the base branch

Im not sure what fails in the build. locally is fine. It says some PMD check failed not sure how to resolve

[siriak]

Update your branch first, it may be already resolved in main

Regarding PMD (cf. logs):

Warning:  PMD Failure: com.thealgorithms.matrix.matrixexponentiation.Fibonacci:58 Rule:UnnecessaryFullyQualifiedName Priority:4 Unnecessary qualifier 'Fibonacci': 'IDENTITY_MATRIX' is already in scope because it is declared in an enclosing type.
Warning:  PMD Failure: com.thealgorithms.matrix.matrixexponentiation.Fibonacci:65 Rule:UnnecessaryFullyQualifiedName Priority:4 Unnecessary qualifier 'Fibonacci': 'FIB_MATRIX' is already in scope because it is declared in an enclosing type.

So it should be enough to remove the Fibonacci from the lines 58 and 65.

Regarding clang-format (cf. logs):

--- ./src/test/java/com/thealgorithms/matrix/InverseOfMatrixTest.java	(original)
+++ ./src/test/java/com/thealgorithms/matrix/InverseOfMatrixTest.java	(reformatted)
@@ -1,8 +1,8 @@

i.e. move the static import to the very top.

@varada610: as an addition to:
#6120 (comment)

After you will fix the PMD issues, please remove this line:

Java/pmd-exclude.properties

Line 58 in a9633c0

com.thealgorithms.matrixexponentiation.Fibonacci=UnnecessaryFullyQualifiedName

[varada610]

thanks @vil02 and @siriak for the help . i see build is green

[varada610]

@siriak @vil02 Require a review to complete the merge

[siriak]

Looks good, thanks!
