Perform file compression and decompression through the TrueCommons I/O framework
In software development, file compression and decompression are very common and useful operations.TrueCommons I/O is a stream compression and decompression framework used in Java programming language.It provides a simple and effective way to compress and decompress files.
First, we need to import the TrueCommons I/O library.You can add the following dependencies to the construction document of the project:
dependencies {
implementation 'org.jvnet.truecommons:truecommons-io:2.4.1'
}
Then, we can use the following code segment to implement the compression operation of the file:
import net.java.truecommons.io.*;
public void compressFile(String sourceFilePath, String compressedFilePath) {
try (OutputStream outputStream = new FileOutputStream(compressedFilePath);
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream);
Output compressedOutput = new TFile(outputStream).archive()) {
IOUtility.copy(new File(sourceFilePath), compressedOutput);
} catch (IOException e) {
e.printStackTrace();
}
}
In the above code, we first create a file output stream and package it in a buffer output stream.Then, using TrueCommons I/O's `TFile` class, we created a` Output` object for compression.Finally, we use the `Copy` method of the` ioutility` class to copy the source file into the compressed output object to achieve compression of the file.
Next, we can use the following code segment to implement the decompression operation of the file:
import net.java.truecommons.io.*;
public void decompressFile(String compressedFilePath, String destinationFilePath) {
try (InputStream inputStream = new FileInputStream(compressedFilePath);
BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
Input compressedInput = new TFile(inputStream).archive()) {
IOUtility.copy(compressedInput, new File(destinationFilePath));
} catch (IOException e) {
e.printStackTrace();
}
}
In the above code, we first create a file input stream and package it in a buffer input stream.Then, using TrueCommons I/O's `TFile` class, we created a` Input` object for decompression.Finally, we use the `Copy` method of the` ioutility` class to copy the data in the compressed input object to the target file to achieve the decompression of the file.
At the same time, in order to make the above code work normally, we also need to construct a path or construct a file that contains TrueCommons I/O libraries.In this way, the compiler can correctly reference the required classes and methods.
File compression and decompression of files through the TrueCommons I/O framework can help us handle files easier during development.It provides a simple and powerful way to compress and decompress files, thereby saving disk space and improving file transmission efficiency.The above code and related configuration can help you quickly use the TrueCommons I/O framework for file compression and decompression.
