Shuffle() is collection class method in Java, works in a random manner based on the permutation logic on a specific group of list elements. Tree are two distinct types of method in a shuffle class(), depending on the particular parameters. Java Collections shuffle(list) Method. Java Collections shuffle(list, random) Method. In this method, we can arrange the characters randomly to generate some random values. Then we will apply the suffle method on it. To perform the vector shuffle, we can use Fisher-Yates shuffle algorithm. In this method, we can learn a linear scan on a vector and swap each ... Read More
The credibility of an efficient coding language depends upon how well it can manage the date and time. In a Java Virtual Environment we get some inbuilt facilities like date, time and calendar to handle the problem related to date and time. java. until date class - In Java, there are many contains those are very important for the program. Date class deals with the operation about the date and time. They are those type of classes which comes with the feature of cloneable, Serializable and comparable interfaces. Extract the current date and time - There are two types ... Read More
The javascript attribute names are case insensitive, so browsers are made in a way to interpret any uppercase characters to lowercase. This means, while using the DOM elements, camel Cased props names need to use their kebab-based (hyphen-delimited) equivalents. So let’s say that you are not sure of the type of value you might receive from the props in Vue.js. Usually, you will want every prop to have a specific type of value. But in a case when you want a prop to have a list of value types, you can use the following syntax to apply the same. props: ... Read More
Vue can be defined as a progressive framework for building user interfaces. It has multiple directives that can be used as per the user needs. The basic core library is mainly focused on building the view layer only and is also easy to pick up other libraries or integrate with them. In the below article, we will see how to add elements to an array. An array is basically a collection of elements. This process of adding elements into an Array can be used in real life in different scenarios. For E.g.: It can be used for creating a shopping ... Read More
Let’s say you have two nested components i.e. a component inside another component. How will you be able to access the child methods from the parent? To access the child method from the parent method you could use ref. Or you can also access the descendants of a parent via the method this.$root (a parent component) which can access the child components using the this.$children array. In the same way, the child can access its parent via the this.$parent. The vue.js basically warns against these for the below two reasons − It tightly couples the parent to the ... Read More
The difference between a computed property and a method is that computed properties are cached, these properties only change when their dependency change. A method will be evaluated every time it is being called. The only useful situation is when the user wants the getter and needs to have the same parameterized. The same situation occurs in vuex also. Example Copy and paste the below code snipped in your Vue project and run the Vue project. You shall see the below output on the browser window. FileName - app.js Directory Structure -- $project/public -- app.js ... Read More
Whenever we insert an image in the front end of any system, it is very important to show the user proper data and images to enhance the user experience. In any project, an image is basically loaded from the remote path URL or from the application. An image may not be loaded properly in the below scenarios − Configuring the wrong image URL Poor Internet/Network connection It is very important to check if an image is loaded or not, because if an image does not load due to poor network connection we can try loading the image ...

Vue can be defined as a progressive framework for building the user interfaces. It has multiple directives that can be used as per the user needs. The basic core library is mainly focused on building the view layer only and is also easy to pick up other libraries or integrate with them. We can dynamically add or remove elements from a list in VueJS using the v-model directive. All the possibilities are binded to a single channel while using this directive. When the user selects an option out of several options, the same will be added to the list. On ... Read More
The way we access the internet has been completely transformed by wireless technologies. We no longer live without wifi, which has made it possible to link some gadgets wirelessly to the internet. Yet, because wireless networks are intrinsically less secure than wired networks, numerous security protocols have been created to address this issue. WiFi Protected Access is one such protocol (WPA). Wired Equivalent Privacy (WEP), a security protocol, was intended to be replaced by WPA once it was discovered to be attackable. WPA was first introduced in 2003, and it immediately emerged as the de facto wireless network security protocol. ... Read More
