Java ArrayList Utilities - Data Structures

Project Overview

This data structures project implements custom collection manipulation algorithms natively using Java. The application focuses on data cleaning operations, programmatic evaluation of integer structures, and mathematical set combinations using dynamic lists.

Algorithmic Mechanics Implemented

The codebase designs robust helper functions to parse, sort, and reconfigure structural elements inside sequential memory:

Maximum Integer Evaluation: Loops linearly through index elements to compare raw unboxed values, dynamically isolating the peak value.
Linear Duplicate Filtration: Generates unique list mirrors by processing continuous evaluation parameters via standard tracking hooks (.contains).
Set Union Computations: Combines distinct lists together into unified data vectors while verifying that existing entities are never overwritten or replicated.

Core Java Source Snippets

Below are the algorithmic tracking methods extracted from the core utility engine:

Java: Duplicate Removal Method

// Takes an ArrayList object as input and removes duplicates in it
public static ArrayList removeDuplicates(ArrayList list) {
    ArrayList result = new ArrayList<>();
    for (int i = 0; i < list.size(); i++) {
        if (!result.contains(list.get(i))) {
            result.add(list.get(i));
        }
    }
    return result;
}

Java: Set Union Logic

// Merges two collections while enforcing element uniqueness
public static ArrayList union(ArrayList list1, ArrayList list2) {
    for (int i = 0; i < list2.size(); i++) {
        if (!list1.contains(list2.get(i))) {
            list1.add(list2.get(i));
        }
    }
    return list1;
}

Program Execution Output

The following block displays the direct console stream output generated by compiling and executing the structural collection array matrices above:

The max integer in the list is : 25 The integers with duplicates are : 23, 5, 3, 7, 5, 6, 4, 25, 2, 2, 5, 2, 4, The integers after removing duplicates are : 23, 5, 3, 7, 6, 4, 25, 2, The integers before union are : 23, 5, 3, 7, 6, 4, 25, 2, 8, 5, 9, 7, 6, The integers after union are : 23, 5, 3, 7, 6, 4, 25, 2, 8, 9,
