JarCastingcode-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.

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));
