code-similarity

Code Similarity provides some implementations of similarity detection algorithm, including Longest Common Subsequence & Cosine Distance

It used to work on data structure courses & exam code check.

Environmental Requirements

JDK 1.8+

Instructions

Add Dependency

<dependency>
	<groupId>com.zhixiangli</groupId>
	<artifactId>code-similarity</artifactId>
	<version>0.0.2</version>
</dependency>

Example

String a = "public static void main(String[] args) {System.out.println(1);}";
String b = "public static void main(String[] args) {System.out.println(2);}";

// default algorithm is Longest Common Subsequence.
CodeSimilarity codeSimilarity = new CodeSimilarity();
System.out.println(codeSimilarity.get(a, b));

// change similarity algorithm to Cosine Distance.
CodeSimilarity cosineSimilarity = new CodeSimilarity(new CosineSimilarity());
System.out.println(cosineSimilarity.get(a, b));
