Java Coding Problems

Getting the Pair class methods

The public methods of a class are accessible via the Class.getMethods() method. This method returns an array of Method:

Method[] methods = clazz.getMethods();// public boolean modern.challenge.Pair.equals(java.lang.Object)// public int modern.challenge.Pair.hashCode()// public int modern.challenge.Pair.compareTo(java.lang.Object)// ...System.out.println("Methods: " + Arrays.toString(methods));

For fetching the actual name of the methods, we can quickly provide a helper method:

public static List<String> getMethodNames(Method[] methods) {  return Arrays.stream(methods)    .map(Method::getName)    .collect(Collectors.toList());}

Now, we only retrieve the names of the methods:

List<String> methodsName = getMethodNames(methods); ...
