Copy of existing static method body

Reports fragments of Java code which are identical to the existing static methods suggesting to reuse these static methods. Reusing existing methods makes code shorter and more readable.

Example:

  static List<String> readFileAndTrim(Path path) throws IOException {
    List<String> lines = Files.readAllLines(path);
    return lines.stream().map(String::trim).toList();
  }
  
  static List<String> readFileAndTrim(String path) throws IOException {
    Path p = Path.of(path);
    List<String> lines = Files.readAllLines(p);
    return lines.stream().map(String::trim).toList();
  }

Here, the second method is quite similar to the first one, and the first one can be reused in its implementation. After the quick-fix is applied, the result will look like this:

  static List<String> readFileAndTrim(Path path) throws IOException {
    List<String> lines = Files.readAllLines(path);
    return lines.stream().map(String::trim).toList();
  }

  static List<String> readFileAndTrim(String path) throws IOException {
    Path p = Path.of(path);
    return readFileAndTrim(p);
  }
