In order to replace all elements of ArrayList with Java Collections, we use the Collections.fill() method. The static void fill(List list, Object element) method replaces all elements in the list with the specified element in the argument.Declaration −The java.util.Collections.fill() method is declared as follows −public static void fill(List
To implement animation on opacity property with CSS, you can try to run the following code:ExampleLive Demo #demo1 { position: absolute; top: 60px; width: 300px; height: 150px; background-color: lightblue; animation: myanim 4s infinite; } #demo2 { position: absolute; top: 90px; left: 30px; width: 300px; height: 150px; background-color: orange; animation: myanim 3s infinite; } #demo3 { position: absolute; top: 120px; left: 60px; width: 350px; height: 150px; background-color: coral; } @keyframes myanim { 30% { opacity: 0.4; } } Showing opacity End div Start div
In order to replace all occurrences of specified element of ArrayList with Java Collections, we use the Collections.replaceAll() method. This method returns true if list contains one or more elements e such that (oldVal==null ? e==null : oldVal.equals(e)).Declaration −The java.util.Collections.replaceAll() is declared as follows −public static boolean replaceAll(List list, T oldVal, T newVal)where oldVal is the element value in the list to be replaced, newVal is the element value with which it is replaced and list is the list in which replacement takes place.Let us see a program to replace all occurrences of specified element of ArrayList with Java ...

We can use Files.move() API to move file from one directory to another. Following is the syntax of the move method.public static Path move(Path source, Path target, CopyOption... options) throws IOExceptionWheresource − Source path of file to be movedtarget − Target path of file to be movedoptions − options like REPLACE_EXISTING, ATOMIC_MOVEExampleimport java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; public class Tester { public static void main(String[] args) { //move file from D:/temp/test.txt to D:/temp1/test.txt //make sure that temp1 folder exists moveFile("D:/temp/test.txt", "D:/temp1/test.txt"); } private static void moveFile(String ...

In order to shuffle elements of ArrayList with Java Collections, we use the Collections.shuffle() method. The java.util.Collections.shuffle() method randomly permutes the list using a default source of randomness.Declaration −The java.util.Collections.shuffle() method is declared as follows −public static void shuffle(List list)Let us see a program to shuffle elements of ArrayList with Java Collections −Example Live Demoimport java.util.*; public class Example { public static void main (String[] args) { ArrayList list = new ArrayList(); list.add(1); list.add(2); list.add(7); list.add(8); list.add(3); list.add(9); ...

Java is a multi-threaded programming language which means we can develop multi-threaded program using Java. A multi-threaded program contains two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources specially when your computer has multiple CPUs.By definition, multitasking is when multiple processes share common processing resources such as a CPU. Multi-threading extends the idea of multitasking into applications where you can subdivide specific operations within a single application into individual threads. Each of the threads can run in parallel. The OS divides processing ... Read More
In order to swap elements of ArrayList with Java collections, we need to use the Collections.swap() method. It swaps the elements at the specified positions in the list.Declaration −The java.util.Collections.swap() method is declared as follows −public static void swap(List list, int i, int j)where i is the index of the first element to be swapped, j is the index of the other element to be swapped and list is the list where the swapping takes place.Let us see a program to swap elements of ArrayList with Java collections −Example Live Demoimport java.util.*; public class Example { public static void ...

Use the border-top-right radius property in CSS to set the top right radius border. You can try to run the following code to implement border-top-right-radius property −ExampleLive Demo #rcorner { border-radius: 25px; border-top-right-radius: 45px; background: orange; padding: 20px; width: 400px; height: 250px; } Rounded border-top-right corner!
