Hexadecimal literal of type long is represented as − long hexLong = 0XABL; For Hexadecimal, the 0x or 0X is to be placed in the beginning of a number. Note − Digits 10 to 15 are represented by a to f (A to F) in Hexadecimal Example Live Demo public class Demo { public static void main(String []args) { long hexLong = 0XABL; System.out.println("Hexadecimal literal of type long: "+hexLong); } } Output Hexadecimal literal of type long:171

We cant touch background thread to main thread directly so handler is going to collect all events which are available in main thread in a queue and posses this queue to looper class.In android Handler is mainly used to update the main thread from background thread or other than main thread. There are two methods are in handler.Post() − it going to post message from background thread to main thread using looper.sendmessage() − if you want to organize what you have sent to ui (message from background thread) or ui functions. you should use sendMessage().This example demonstrate about how to ...

For Hexadecimal, the 0x or 0X is to be placed in the beginning of a number. Note − Digits 10 to 15 are represented by a to f (A to F) in Hexadecimal Here are some of the examples of hexadecimal integer literal declared and initialized as int. int one = 0X123; int two = 0xABC; Example Live Demo public class Demo { public static void main(String []args) { int one = 0X123; int two = 0xABC; System.out.println("Hexadecimal: "+one); System.out.println("Hexadecimal: "+two); } } Output Hexadecimal: 291 Hexadecimal: 2748

Before getting into searchview example, we should know what is search view in android, search view is just like search box in HTML. we can search anything from particular list items.This example demonstrate about how to integrate search view in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml.         In the above code we are giving search view and listview because search view going to search element from ...

The System.out.format is used in Java to format output. Here, let’s say the following is our long. long val = 787890; To format, we have considered the following that justifies the output. System.out.format("%d%n", val); System.out.format("%9d%n", val); System.out.format("%+9d%n", val); System.out.format("%08d%n", val); System.out.format("%, 9d%n", val); The following is the complete example that displays the difference in output as well. Example Live Demo import java.util.Locale; public class Demo { public static void main(String []args) { long val = 787890; System.out.format("%d%n", val); ... Read More

To compare two Java long arrays in Java, use Arrays.equals() method. Let’s say we have the following long arrays. long[] arr1 = new long[] { 767, 568, 555, 897, 678 }; long[] arr2 = new long[] { 456, 756, 555, 999, 678}; long[] arr3 = new long[] { 767, 568, 555, 897, 678 }; Now, we can compare the equality of these arrays using the equals() method. Arrays.equals(arr1, arr2); Arrays.equals(arr2, arr3); Arrays.equals(arr1, arr3); The following is the complete example. Example Live Demo import java.util.*; public class Demo { public ... Read More

Before getting into the Navigation view example, we should know about navigation view. Navigation view is just like a sliding menu in HTML. Navigation view is extended by navigatoin drawer. Most of use cases of Navigation view is used to redirect different activities or show profile information.This example demonstrate about how to integrate NavigationView in ActionBarStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step2 − While creating project we should select Navigation drawer activity as shown belowAfter selecting navigation drawer activity click on ...

In this article, we will sort a long array in Java. We will be using the Arrays.sort() method of Arrays class which is present in java.util package. It will helps us to organize data in ascending order, making it easier to use. We'll start with an unsorted array, display it, sort it using Java’s built-in method, and then display the sorted array.  Problem Statement Given an unsorted array of long numbers write a Java program to sort the unsorted array. Input Unsorted long array: 987, 76, 5646, 96, 8768, 8767 Output Sorted long array:7696987564687678768 Steps to sort the long Array Following are ... Read More

Before getting into Glide example, we should know what is glide, Glide is an image processing library developed by muyangmin. Using glide library we can show image, decode images, cache images, animated gifs and many more.This example demonstrate about how to integrate glide in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code in build.gradle(Module:app).apply plugin: 'com.android.application' android {    compileSdkVersion 28    defaultConfig {       applicationId "com.example.andy.myapplication"       minSdkVersion 15       ...

The intersection of the two arrays results in those elements that are contained in both of them. If an element is only in one of the arrays, it is not available in the intersection. An example of this is given as follows − Array 1 = 1 2 5 8 9 Array 2 = 2 4 5 9 Intersection = 2 5 9 A program that demonstrates the intersection of two sorted arrays in Java is given as follows. Example Live Demo public class Example { public static void main(String args[]) ... Read More
