A LongFunction in Java is a functional interface which takes one argument of type long and returns a result of some other type. Functional interface is an interface that have only one abstract method. To use this interface first you have to import java.util.function package. The functional method of this interface is ‘apply()’ which takes long value as an argument and returns function result denoted by R. Syntax R apply(long value); Algorithm In order to effectively implement this functional interface into your work, there are three defining steps one must abide by beforehand. First off, establishing an ... Read More

A LongToIntFunction in Java is a functional interface which takes one argument of type long and returns a result of int type. Functional interface is an interface that have only one abstract method. To use this interface first you have to import java.util.function package. The functional method of this interface is ‘applyAsInt()’ which takes long value as an argument and returns int valued result. Syntax int applyAsInt(long value); Algorithm To implement this functional interface, follow these steps − Step 1 − Create an instance of the functional interface by defining a lambda expression that implements the applyAsInt(long value) method. ...

Resources play an important role during runtime by providing necessary files that enable smooth software operation. These resources are accessible through a classpath system which allows them to be read from or written into with ease. For managing this process effectively within Java programs, several APIs such as the ClassLoader and Class classes exist - these offer various features for identifying resource locations within the app's environment and retrieving related information while at it. Algorithm Step 1 − Get the class loader for the current class Step 2 − Load a resource as a URL/Inputstream.For those who choose to ... Read More

The implementation of TextWatcher in Android enables developers to actively monitor and respond to real-time changes made to an EditText widget. The TextWatcher interface presents three essential methods: beforeTextChanged(), onTextChanged(), and afterTextChanged(). These methods are called at different stages during the text editing process, providing valuable opportunities for observation, intervention, and subsequent actions. To implement TextWatcher, there are three approaches available: utilizing an anonymous inner class, applying inline implementation, or implementing the TextWatcher interface within your activity or fragment. In each method, one needs to override the necessary TextWatcher methods. After that, the TextWatcher should be ... Read More

The TabLayout with icons has become a popular UI component in Android development. It simplifies navigation within an app by offering a horizontal layout of tabs. Each tab represents a distinct category or feature and can be enhanced visually by incorporating icons. This combination of icons and labels makes it easier for users to grasp the purpose of each tab. By selecting a tab, the corresponding content is displayed. This is typically done within a ViewPager. To implement TabLayout with icons, one needs to create the necessary layouts and manage fragments or activities for each tab's content. It ... Read More

Java enables the implementation of a stack by utilizing an array and generics. This creates a ve-rsatile and reusable data structure that operates on the principle of Last-In-First-Out (LIFO). In this principle, elements are added and removed from the top. By utilizing an array as its foundation, it ensures efficient memory allocation and access. Additionally, by incorporating generics, the stack becomes capable of accommodating elements of different types, enhancing its versatility. The implementation involves the definition of a Stack class that incorporates a generic type parameter. It includes essential methods such as push(), pop(), peek(), and isEmpty(). The ... Read More
