What is the JHeaps library?
JHeaps is a free library that provides various heap implementations written in Java.
- It is easy to use
- The data structures have a well defined interface
- It is fast and well documented
- The heaps are written in a similar way as in the JDK
- It does not depend on other libraries, so classpathing ‘jheaps.jar’ is sufficient to use in your project.
- Supports JDK 8 and above
The library contains an extensive collection of heap data structures such as:
- Fibonacci mergeable and addressable heaps
- Simple Fibonacci heaps
- Pairing mergeable and addressable heaps
- Costless-meld variant of Pairing heaps
- Rank-Pairing (type-1) mergeable and addressable heaps
- Leftist mergeable and addressable heaps
- Explicit binary tree addressable heaps
- Binary tree soft heaps
- Skew heaps
- Hollow mergeable and addressable heaps
- Double-ended mergeable and addressable heaps
- Reflected Fibonacci heaps
- Reflected Pairing heaps
- Binary heaps
- Binary addressable heaps
- D-ary heaps
- D-ary addressable heaps
- Binary weak heaps
- Binary weak heaps supporting bulk insertion
- Highly optimized binary heaps for integer keys using the Wegener bottom-up heuristic and sentinel values
- Double-ended array-based
- Binary MinMax heaps
- Monotone heaps
- Addressable radix heaps with double, long, int or BigInteger keys
- Non-addressable radix heaps with double, long, int or BigInteger keys
Latest version & Requirements
The latest version of JHeaps is 0.14.
Every JHeaps release is published to the Maven Central Repository. You can add a dependency from your project as follows:
<groupId>org.jheaps</groupId> <artifactId>jheaps</artifactId> <version>0.14</version>
Extensive documentation of the available classes and interfaces can be found in the latest version’s javadoc.
The library requires JDK 8 and above.
We also provide Python bindings which compile the Java library into a native shared library using GraalVM. The result is a native self-contained library with no dependency on the JVM! For more information see the following links:
