To create a roll in animation effect with CSS, you can try to run the following code −ExampleLive Demo .animated { background-image: url(/css/images/logo.png); background-repeat: no-repeat; background-position: left top; padding-top:95px; margin-bottom:60px; -webkit-animation-duration: 10s; animation-duration: 10s; -webkit-animation-fill-mode: both; animation-fill-mode: both; } @-webkit-keyframes rollIn { 0% { opacity: 0; -webkit-transform: translateX(-100%) rotate(-120deg); } 100% { opacity: 1; -webkit-transform: translateX(0px) rotate(0deg); } } @keyframes rollIn { 0% { opacity: 0; transform: translateX(-100%) rotate(-120deg); } 100% { opacity: 1; transform: translateX(0px) rotate(0deg); } } .rollIn { -webkit-animation-name: rollIn; animation-name: rollIn; } Reload page function myFunction() { location.reload(); }
The getName() method is used to get the names of the entities such as interface, class, array class, void etc. that are represented by the class objects. These names are returned in the form of a string. The getPackage() method gets the package for the given class.A program that gets the class name for various objects is given as follows −Example Live Demopackage Test; import java.io.IOException; import java.util.HashMap; public class Demo { public static void main(String args[]) throws IOException { Object obj = "string"; System.out.println("The class name is: " + obj.getClass().getName()); ...

The canonical name of a class can be obtained using the java.lang.Class.getCanonicalName() method. This method returns the canonical name of the underlying class and returns null if there is no canonical name for the underlying class.A program that demonstrates the getCanonicalName() method to obtain the canonical name is given as follows −Example Live Demopackage Test; import java.lang.*; public class Demo { public static void main(String[] args) { Demo obj = new Demo(); Class c = obj.getClass(); System.out.println("The canonical name of the underlying Class is: " + c.getCanonicalName()); } }OutputThe canonical ...

In order to sort ArrayList in Descending order using Comparator, we need to use the Collections.reverseOrder() method which returns a comparator which gives the reverse of the natural ordering on a collection of objects that implement the Comparable interface.Declaration − The java.util.Collections.reverseOrder() method is declared as follows -public static Comparator reverseOrder()Let us see a program to sort an ArrayList in Descending order using Comparator with Java Collections −Example Live Demoimport java.util.*; public class Example { public static void main (String[] args) { ArrayList list = new ArrayList(); list.add(10); list.add(50); ...

In order to create and demonstrate an immutable collection in Java, we use the unmodifiableCollection() method. This method returns an unmodifiable and immutable view of the collection.Declaration − The java.util.Collections.unmodifiableCollection() method is declared as follows -public static Collection unmodifiableCollection(Collection
In order to get Array Dimensions in Java, we use the getClass(), isArray() and getComponentType() methods with decision making in combination with iterative statements.The getClass() method method returns the runtime class of an object. The getClass() method is a part of the java.lang.Object class.Declaration − The java.lang.Object.getClass() method is declared as follows −public final Class getClass()The isArray() method checks whether the passed argument is an array. It returns a boolean value, either true or falseSyntax - The isArray() method has the following syntaxArray.isArray(obj)The getComponentType() method returns the Class denoting the component type of an array. If the class is not an ... Read More
One of the methods of the Timer class is void scheduleAtFixedRate(TimerTask task, long delay, long period). This method schedules the specified task for repeated fixed-rate execution, beginning after the specified delay.In fixed-rate execution, each execution is scheduled with respect to the scheduled run time of the initial execution. Fixed-rate execution is apt for repetitive activities that are respond to absolute time. Likewise, fixed-rate execution is appropriate for scheduling multiple repeating timer tasks that must remain in sync.Declaration − The java.util.Time.scheduleAtFixedRate(TimerTask task, long delay, long period) method is declared as follows −public void scheduleAtFixedRate(TimerTask task, long delay, long period)Here, task is ...

In order to determine if an object is an Object is an array in Java, we use the isArray() and getClass() methods.The isArray() method checks whether the passed argument is an array. It returns a boolean value, either true or falseSyntax - The isArray() method has the following syntax -Array.isArray(obj)The getClass() method method returns the runtime class of an object. The getClass() method is a part of the java.lang.Object class.Declaration − The java.lang.Object.getClass() method is declared as follows −public final Class getClass()The getClass() method acts as the intermediate method which returns an runtime class of the object, which enables the terminal ...

To format message with percentage fillers in Java, we use the MessageFormat class. The MessageFormat class gives us a way to produce concatenated messages which are not dependent on the language. The MessageFormat class extends the Serializable and Cloneable interfaces.Declaration - The java.text.MessageFormat class is declared as follows −public class MessageFormat extends FormatThe MessageFormat.format(pattern, params) method formats the message and fills in the missing parts using the objects in the params array matching up the argument numbers and the array indices.The format method has two arguments, a pattern and an array of arguments. The pattern contains placeholder in {} curly ... Read More
In order to generate Random boolean in Java, we use the nextBoolean() method of the java.util.Random class. This returns the next random boolean value from the random generator sequence.Declaration −The java.util.Random.nextBoolean() method is declared as follows −public boolean nextBoolean()Let us see a program to generate random boolean in Java −Example Live Demoimport java.util.Random; public class Example { public static void main(String[] args) { Random rd = new Random(); // creating Random object System.out.println(rd.nextBoolean()); // displaying a random boolean } }OutputtrueNote − The output might vary on Online Compilers.
