+# Treeset
+*TreeSet is a class in Java that implements the Set interface. It is used to store a sorted collection of unique elements, meaning it does not allow duplicate values.* 
+*TreeSet internally uses a Red-Black tree data structure to maintain the elements in sorted order.*
+
+## There are many methods related to TreeSet Here are most common that are used
+
+### 1. add(E element):
+* This method adds the specified element to the TreeSet if it is not already present. If the element is already present, the set remains unchanged.
+
+### 2. contains(Object o):
+* This method returns true if the TreeSet contains the specified element; otherwise, it returns false.
+
+### 3. remove(Object o):
+* This method removes the specified element from the TreeSet if it is present. Returns true if the element was present and successfully removed; otherwise, returns false.
+
+### 4. size():
+* This method returns the number of elements in the TreeSet.
+
+### 5. isEmpty():
+* This method returns true if the TreeSet contains no elements; otherwise, returns false.
+
+### 6. clear():
+* This method removes all elements from the TreeSet.
