Java Program 3: Find first duplicate character in the given string

Let us understand the question first, we have to find the character in the given string which is repeated twice and first. Let us understand with examples:

Java Program 2: Verify the given mobile number contains 10 digits and starts with 7, 8 or 9 only

There will be many approaches to solve this problem, we will use regular expressions to solve this in this post.

First we will regular expression that satisfies given conditions, then we will match with the given inputs.

Java Program 1: How to read characters of a String?

String is a character sequence enclosed in double quotes. We can't access its characters one by one like we access the values of an array (a[0], a[1] and etc.) directly.

Post 2: Attaching Screenshot to failed tests in ExtentReports Version 4

In Post 1 we have learned generating the extent reports using ExtentReportsV4, in this postwe will learn about adding the screenshot to failed test cases. This will be continuation to Post 1, please go through it first then continue this.

Post 1: Generate Results Report In Selenium with ExtentReports Version 4

ExtentReports V4 has been released and it is more beautiful and interactive. In this post we will discuss about generating the reports using Extentreports V4 in Selenium with TestNG.

Why we need to down cast WebDriver reference for JavaScriptExecutor and TakesScreenshot in Selenium?

Let us understand this with below java program example.

I have class A and interface B as shown below, class A is having a method call sayBye(), interface B is having a declared method sayHello().

Now let class A implement interface B, and implement the sayHello() method of interface B in class A as shown below.
