Hashmap in Java

HashMap is a component of the Java Collections Framework that implements the Map interface. It offers a key-value pair data structure in which elements are stored as a combination of keys and their corresponding values. HashMap does not support duplicate keys, but it does support mapping multiple values to the same key.

User-defined data types in java

By defining your own classes, you can produce user-defined data types in Java. These classes let you create unique data structures that encapsulate data and action. Here is how to make a Java user-defined data type:

Method Overriding in Java

Overriding methods is a key idea in Java object-oriented programming. It enables a subclass to provide a particular implementation of a method defined in the superclass.

C# provides the while loop to repeatedly execute a block of code as long as the specified condition returns false. The while loop starts with the while keyword, and it must include a boolean conditional expression inside brackets that returns either true or false. It executes the code block until the specified conditional expression returns false. The condition is given in the beginning of the loop and all statements are executed till the given boolean condition satisfies when the condition becomes false, the control will be out from the while loop else It executes the code block until the specified conditional expression returns false.

Vector In Java

A dynamic array implementation that is a part of the Java Collections Framework is the Vector class in Java. It offers a resizable array that can expand or contract as necessary. Similar to ArrayLists, vectors are thread-safe for use in multi-threaded situations since they are synchronised.

Chapter 3 CSS (Define ID in CSS)

In HTML and CSS, an ID (identifier) is a unique attribute used to identify an individual element on a webpage. Each ID must be unique within the document, distinguishing one element from all others.

Array List

In Java, the ArrayList class implements the List interface as a resizable array. It offers dynamic arrays that can expand or contract in size as needed. ArrayLists are a component of the Java Collections Framework and provide a variety of methods for modifying the elements contained in them.

java.lang.NumberFormatException

A NumberFormatException is produced in Java when you try to convert a string to a numeric type (such as int, double, float, etc.) but the string's format is incompatible with the required format for that numeric type. This is common when using parsing techniques such as Integer.parseInt(), Double.parseDouble(), or Float.parseFloat().
