What is FXML document in Java?
FXML is a markup language for describing user interfaces for JavaFX applications. It is an XML-based language created by Oracle to enable developers to define the user interface of a JavaFX application in separate files from application logic. This also allows users to create components of their application without coding and to develop easily maintainable and extensible code.
What makes a great application in Java?
A great application in Java needs to consider the needs of its users and the goals of the organization that has requested it. It should be designed for scalability, maintainability, and reliability. The code should be written in a clear and concise manner, with a robust set of unit tests to verify its correctness. Any external components needed should be carefully selected so that the application can leverage existing libraries to speed development and reduce technical debt. A great application should also use appropriate design patterns for its given problem domain, so that it is extensible and maintainable. Finally, it should be designed and built with security as a primary concern, ensuring that all data is safe from any malicious actors.
const date = new Date('Oct 11 2020 13:20:01');
const newTime = date.getMinutes() - 20;
console.log(date); //Output Mon Oct 11 2020 13:00:01 GMT+1000
1. Global Scope - Variables declared outside of any function are in the global scope, and all scripts and functions on a web page can access them.
2. Local/Function Scope - Variables declared within a functions are in the local/function scope and are only available within that function.
3. Block Scope - Variables declared with the let keyword in a block of code is in a block scope and can only be accessed within that block.
4. Lexical Scope - Variables declared inside inner functions are in a lexical scope, and are only accessible by those inner functions.
Is Java a good choice for backend development?
Yes, Java is a good choice for backend development. It is one of the most popular tools for developing robust, enterprise-scale applications. Its versatility and scalability make it suitable for a variety of projects. It also has a powerful set of frameworks and libraries available to help developers build high-performing applications quickly and efficiently.
Binary search is an algorithm used to locate an element within an already sorted array. It works by dividing the array into two parts, comparing the element in the middle of the array to the element it is searching for and then either searching the lower half of the array or the upper half as appropriate. If the element is not found, the process is repeated on the chosen half until the element is found or the array runs out. Binary search is a lot faster than linear search, making it an ideal algorithm for large array searches.
