Tyrus
Eclipse Tyrus is the open source JSR 356 - Java API for WebSocket
Eclipse Tyrus is the open source JSR 356 - Java API for WebSocket reference implementation for easy development of WebSocket applications.Eclipse Tyrus is also a Jakarta WebSocket 2.0 compatible implementation. WebSocket protocol defined by IETF provides bi-directional communication between the server and the remote host. The pros are mainly the ability to communicate both ways, low latency and small communication overhead. Therefore Tyrus and WebSocket in general are suitable for web applications that require sending a huge volume of relatively small messages like online games or market ticker broadcasting. -

ZXing Android Embedded
Barcode scanner library for Android, based on the ZXing decoder
ZXing Android Embedded is a barcode scanning library for Android, using ZXing for decoding. The project is loosely based on the ZXing Android Barcode Scanner application but is not affiliated with the official ZXing project. By default, only SDK 24+ will work, even though the library specifies 19 as the minimum version. For SDK versions 19+, one of the changes changes below are required. Some older SDK versions below 19 may work, but this is not tested or supported. While this is not the primary purpose of this library, it does include basic support for generating some barcode types. To change the orientation, specify the orientation in your AndroidManifest.xml and let the ManifestMerger to update the Activity's definition. The camera permission is required for barcode scanning to function. It is automatically included as part of the library. On Android 6 it is requested at runtime when the barcode scanner is first opened. -

java-string-similarity
Implementation of various string similarity and distance algorithms
Implementation of various string similarity and distance algorithms: Levenshtein, Jaro-winkler, n-Gram, Q-Gram, Jaccard index, Longest Common Subsequence edit distance, cosine similarity. A library implementing different string similarity and distance measures. A dozen of algorithms (including Levenshtein edit distance and sibblings, Jaro-Winkler, Longest Common Subsequence, cosine similarity etc.) are currently implemented. The main characteristics of each implemented algorithm are presented below. The "cost" column gives an estimation of the computational cost to compute the similarity between two strings of length m and n respectively. If the alphabet is finite, it is possible to use the method of four russians (Arlazarov et al. "On economic construction of the transitive closure of a directed graph", 1970) to speedup computation. This was published by Masek in 1980 ("A Faster Algorithm Computing String Edit Distances"). -

ta4j
A Java library for technical analysis
Ta4j is an open-source Java library for technical analysis. It provides the basic components for the creation, evaluation, and execution of trading strategies. Ta4j is available on Maven Central. You can also download example code from the maven central repository. The wiki is the best place to start learning about ta4j. For more detailed questions, please use the issues tracker. We can calculate indicators over this bar series, in order to forecast the direction of prices through the study of past market data. Then we have to build our trading strategy.
