File Sorting Documentation

Introduction

Sorting file content is essential for many applications, such as arranging log files, processing structured data, and enhancing readability. The file-worker library provides a simple and efficient way to sort file content using customizable comparators.

Imagine you are processing a dataset and need to sort the lines alphabetically or numerically. This library makes such tasks seamless and efficient.

Features Overview

• Sort file content using custom comparators.
• Support for different encoding formats.
• Efficient sorting for large text files.

Getting Started

For installation and dependencies, refer to the Getting Started guide.

Sorting Files with SortFileExtensions

The SortFileExtensions class provides methods to sort file content based on a custom comparator.

Example: Sorting a File Alphabetically

File file = new File("unsorted.txt");
SortFileExtensions.sort(file, Comparator.naturalOrder(), "UTF-8");

System.out.println("File sorted successfully!");

Example: Sorting a File in Reverse Order

SortFileExtensions.sort(file, Comparator.reverseOrder(), "UTF-8");

System.out.println("File sorted in reverse order!");

Unit Test Coverage

The SortFileExtensionsTest class ensures sorting functionality:

@Test
public void testSort() throws IOException {
    File file = new File("test.txt");
    StoreFileExtensions.toFile(file, "Banana
Apple
Cherry");

    SortFileExtensions.sort(file, Comparator.naturalOrder(), "UTF-8");

    List<String> lines = ReadFileExtensions.readLinesInList(file);
    assertEquals("Apple", lines.get(0));
    assertEquals("Banana", lines.get(1));
    assertEquals("Cherry", lines.get(2));
}

Handling Large Files

Sorting large files can be memory-intensive. This library optimizes sorting by processing files efficiently.

Example: Sorting a Large File

File largeFile = new File("bigdata.txt");
SortFileExtensions.sort(largeFile, Comparator.naturalOrder(), "UTF-8");

System.out.println("Large file sorted successfully!");

Unit Test Coverage

@Test
public void testSortLargeFile() throws IOException {
    File file = new File("large_data.txt");
    StoreFileExtensions.toFile(file, "Zebra
Lion
Elephant
Antelope");

    SortFileExtensions.sort(file, Comparator.naturalOrder(), "UTF-8");

    List<String> lines = ReadFileExtensions.readLinesInList(file);
    assertEquals("Antelope", lines.get(0));
    assertEquals("Elephant", lines.get(1));
    assertEquals("Lion", lines.get(2));
    assertEquals("Zebra", lines.get(3));
}
