For maven, the natives will import automatically by your system family and architecture.
<dependency>
<groupId>com.aayushatharva.brotli4j</groupId>
<artifactId>brotli4j</artifactId>
<version>1.17.0</version>
</dependency>
For gradle, we have to write some logic to import native automatically. Of course, you can add native(s) as dependency manually also.

Call Brotli4jLoader.ensureAvailability()
in your application once before using Brotli4j. This will load
Brotli4j native library automatically using automatic dependency resolution.
However, its possible to load native library manually from custom path by specifying System Property "brotli4j.library.path"
.
public class Example {
public static void main(String[] args) {
// Load the native library
Brotli4jLoader.ensureAvailability();
// Compress data and get output in byte array
byte[] compressed = Encoder.compress("Meow".getBytes());
// Decompress data and get output in DirectDecompress
DirectDecompress directDecompress = Decoder.decompress(compressed); // or DirectDecompress.decompress(compressed);
if (directDecompress.getResultStatus() == DecoderJNI.Status.DONE) {
System.out.println("Decompression Successful: " + new String(directDecompress.getDecompressedData()));
} else {
System.out.println("Some Error Occurred While Decompressing");
}
}
}
public class Example {
public static void main(String[] args) {
// Load the native library
Brotli4jLoader.ensureAvailability();
FileInputStream inFile = new FileInputStream(filePath);
FileOutputStream outFile = new FileOutputStream(filePath + ".br");
Encoder.Parameters params = new Encoder.Parameters().setQuality(4);
BrotliOutputStream brotliOutputStream = new BrotliOutputStream(outFile, params);
int read = inFile.read();
while (read > -1) {
brotliOutputStream.write(read);
read = inFile.read();
}
// Close the BrotliOutputStream. This also closes the FileOutputStream.
brotliOutputStream.close();
inFile.close();
}
}
public class Example {
public static void main(String[] args) {
// Load the native library
Brotli4jLoader.ensureAvailability();
FileInputStream inFile = new FileInputStream(filePath);
FileOutputStream outFile = new FileOutputStream(decodedfilePath);
BrotliInputStream brotliInputStream = new BrotliInputStream(inFile);
int read = brotliInputStream.read();
while (read > -1) {
outFile.write(read);
read = brotliInputStream.read();
}
// Close the BrotliInputStream. This also closes the FileInputStream.
brotliInputStream.close();
outFile.close();
}
}
Windows-AArch64: Brotli4j is compiled with JDK 11 with JDK 8 as target because JDK 8 Windows Aarch64 builds are not available at the moment. However, it should not cause any problem on running it on JDK 8 or plus.
RISC-V64: This platform is only supported by JDK 11+ (i.e. JDK 11, JDK 17, JDK 21, atm.). However, Since Brotli4j was always compiled with JDK 8, we're cross-compiling RISC-V64 native module bytecode with JDK 8. This should not break existing application using Broti4j. However, you should use JDK 11+ for using Brotli4j on RISC-V64 platform.
JProfiler is supporting Brotli4J with its full-featured Java Profiler. JProfiler's intuitive UI helps you resolve performance bottlenecks, pin down memory leaks and understand threading issues. Click below to know more:
