TreeMap is a class of Java Collection Framework that implements NavigableMap Interface. It stores the elements of the map in a tree structure and provides an efficient alternative to store the key-value pairs in sorted order. Note that while creating objects of TreeMap it is necessary to use either the Comparable Interface or Comparator Interface so that we can maintain the sorting order of its elements otherwise, we will encounter a java.lang.ClassCastException. In this article, we are going to explain how to use the Comparable and Comparator Interfaces to fix this ClassCastException in TreeMap. Fixing java.lang.ClassCastException in TreeMap ... Read More

The TreeSet is a generic class of Java Collection Framework that implements the SortedSet Interface. It stores the elements of the set in a tree structure. Furthermore, all the elements are stored in a sorted manner and they must be mutually comparable if we are attempting to add custom class objects otherwise we will encounter a java.lang.ClassCastException. Here, custom class objects mean user-defined objects that are created with the help of a constructor. To fix this ClassCastException in TreeSet we can use either the Comparator Interface or the Comparable Interface. Let's discuss them in detail. The general ... Read More

The TreeSet is a generic class of Java Collection Framework that implements the SortedSet Interface. It stores the elements of the set in a tree structure. Furthermore, all the elements are stored in a sorted manner and they must be mutually comparable if we are attempting to add custom class objects otherwise we will encounter a java.lang.ClassCastException. Here, custom class objects mean user-defined objects that are created with the help of a constructor. One way to fix this ClassCastException is by using a custom comparator. Let's discuss it in detail. The general syntax for TreeSet is as ... Read More

LinkedHashMap is a generic class of Java Collection Framework that implements Map Interface. As the name suggests, it is a sub-class of the HashMap class and uses a doubly LinkedList to store the entries in insertion order. It maintains Key-Value pair of entries. The Key is an object that is used to fetch and receive value associated with it. Hence, we can use this key along with 'get()' method to get all the values from LinkedHashMap. The aim of this article is to explain different ways to print all values of the LinkedHashMap. Java Program to Get all ... Read More

LinkedHashMap is a generic class of Java Collection Framework that implements Map Interface. As the name suggests, it is a sub-class of the HashMap class and uses a doubly LinkedList to store the entries in insertion order. However, LinkedHashMap does not do any kind of indexing to store the entries, therefore, it is quite a challenge to get specified values from LinkedHashMap with the help of an index. The aim of this article is to explain how to find a value from LinkedHashMap using the index. Java Program to Get a Value from LinkedHashMap by Index Before jumping ... Read More

LinkedHashSet is a class of Java Collection Framework that implements the Set interface and extends the HashSet class. It is a linked list type of collection class. It stores and returns the objects in the order in which they were inserted. Finding maximum and minimum elements from a LinkedHashSet collection is one of the common tasks that are frequently asked in exams and even in job interviews. In this article, we are going to explore a few approaches for performing the given task. Program to get Minimum and Maximum elements from LinkedHashSet To find the maximum ... Read More

In this article, we'll make two channels in Go: one for even numbers and another for odd numbers. We are going to send the even numbers to the even channel and the odd numbers to the odd channel.Here we are going to use two different methods: using creating even and odd channels and Sending Even and Odd Numbers to Channels  along with examples to elaborate the concept. Syntax close(evenChan) This is a built in function call used to close a channel. This make sure that no more value will be sent on the channel, and a send operation on ... Read More

In this article, we focus on making a buffered channel of size 5 and sending 10 integers to the channel using a loop. The program illustrates how to make and utilize a buffered channel to send large values.Here we are going to use two different methods: by Sending integers to the channel using a loop and by creating a buffered channel along with examples to elaborate the concept. Syntax ch := make(chan int, bufferSize) The Syntax ch := make(chan int, bufferSize) creates a buffered channel ch of type int with a specified buffer size, allowing the sender to send ... Read More

In Java, Map is an object that stores its element in key-value pairs. The Key is an object that is used to fetch and receive value associated with it. The keys must be unique, but the values associated with them may be duplicated depending on the type of Map class we use. There are several approaches to find an entry with the largest key in Java map and these approaches also depend on the type of Map class we are working with. In this article, we will discuss how to find the entry with largest key in HashMap ... Read More

In this article, the Golang program is designed to recover details of  a car utilizing its number plate and engine number. It allows users to input the car's data and bring important details such as owner name, registration details, and contact data. By giving  inputs, clients can rapidly get the data they require about a particular car.Here we are going to use three different methods: GetCarDetailsByPlateAndEngine, using validateinput  and using the retrievecardetails function along with examples to elaborate the concept. Syntax func GetCarDetailsByPlateAndEngine(plateNumber string, engineNumber string) (*CarDetails, error) the GetCarDetailsByPlateAndEngine function takes two string parameters (plateNumber and engineNumber), and ...
