Find the Maximum Element of Java Hashset

A collection that makes use of a hash table for storage factors and makes use of the hashing technique is created using the Java HashSet class. The type of implementation of Set. It implements the et interface and inherits the abstract class. The primary characteristic is that it uses an internal hash table and prohibits duplication.

Example 1:

Input:

[12, 45, 78, 34, 23, 89]

Output:

The Maximum Element of the Hashset is 89.

Explanation:

The input is a hash set with the elements in it is {12, 45, 78, 34, 23, 89}. In the set, the maximum element is 89.

Example 2:

Input:

[5, 5, 15, 25, 35]

Output:

The Maximum Element of the Hashset is 35.

Explanation:

A hash set with the elements {5, 15, 25, 35} is the input. The maximum element in a hash set is 35 since duplicate elements are automatically eliminated.

Example 3:

Input:

[9]

Output:

The Maximum Element of the Hashset is 9

Explanation:

The input is a hash set with the single element {9} in it. Consequently, the maximum element is 9.

Approach: Using for loop

The code is extremely sophisticated since it makes use of a hash set, which offers constant-time performance for simple operations like iteration and addition. The proper initialization for determining the maximum value without adding garbage data is ensured by using an Integer.MIN_VALUE. Using the HashSet's capacity for efficient iteration without the requirement for an index or sorting, the improved loop iterates directly over its elements. By avoiding auxiliary data structures and working directly with the HashSet's built-in structure, this approach maximizes memory and computational effectiveness for this task.

Algorithm:

Step 1: Create a HashSet object.

Step 2: Add elements to the object that has been created.

Step 3: Make a variable, then set its value to MIN_VALUE.

Step 4: Use each loop to iterate.

Implementation:

Output:

 The Elements in the HashSet is [36, 23, 87, 41, 58, 75, 12] The Maximum element in the HashSet is given by 87 

Approach: Using Collection.min() method of HashSet of collection class.

A HashSet is used in the code for storing and arranging a group of distinct String elements. Using the normal ordering of String objects in Java, the Collections.max() function is used to determine the lexicographically biggest string in the HashSet. By using the Collections utility class's built-in capability instead of manual iteration, this method ensures a clear and efficient implementation. Since the HashSet is hash-based, it ensures that there are no duplicate elements and offers effective insertion and lookup. The code shows how to seamlessly integrate essential Java tools for managing collections and carrying out tasks like determining the maximum element.

Syntax:

Parameters: The above method uses the collection collect as a parameter, the maximum value of which must be established.

Return Value: Based on the elements' inherent ordering, this function supplies the collection's maximal element.

Exception: If the collection is empty, this function throws a NoSuchElementException.

Algorithm:

Step 1: Create a HashSet object

Step 2: Add elements to the generated object.

Step 3: To find out which string is the maximum among the non-duplicated list that is created, use the Collection.max() method. Be aware that there won't be a single duplicate element.

Implementation:

Output:

 The Elements in the HashSet is [the, Hello, Welcome, to, World] The maximum String in a HashSet is given by : to
