What is Array in Java?

An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You have seen an example of arrays already, in the main method of the "Hello World!" application. This section discusses arrays in greater detail.

How to declare and initialize declare in Java?

We've made a research and found out 3 ways to do it.

For primitive types:

int[] myIntArray = new int[3];
int[] myIntArray = {1,2,3};
int[] myIntArray = new int[]{1,2,3};

For classes, for example String:

String[] myStringArray = new String[3];
String[] myStringArray = {"a","b","c"};
String[] myStringArray = new String[]{"a","b","c"};

The third way of initialising is useful when you declare the array first and then initialise it. Cast is necessary here.

String[] myStringArray;
myStringArray = new String[]{"a","b","c"};

Microsoft to Use Chromium for Edge Browser

The company has already placed the repository on GitHub to attract new members to the development of the browser

Microsoft Vice President Joe Belfiore said that from December 6, 2018, the company will use the Chromium engine in the Microsoft Edge browser. According to him, Microsoft also plans to develop browsers for smartphones and other devices.

The company has already placed the repository on GitHub to attract new members to the development of the browser. Microsoft expects that the transition to the new engine will be a big step in the development of Microsoft Edge. For example, the browser will finally be adapted for macOS.

According to Belfiore, the company plans to improve the project in three areas:

  • Users will get hardware integration, improved browser compatibility with sites and reduced power consumption of devices when using it.
  • Web developers will appreciate the reduced fragmentation of a web platform for testing sites.
  • The corporate IT sector will get the compatibility of old and new Windows applications that run in the browser.

He noted that during the year the company would work “under the hood” of Microsoft Edge, and named several key stages of this process. For example, the transition to a platform compatible with the Chromium engine for developing a desktop version of the browser. It is also planned that most platforms and all versions of Windows will support Microsoft Edge.
