Java program to print sum of digits from a given string

• Iterate through each character in the string

• Check if the character is a digit using Character.isDigit() method

• Convert the digit character to integer using Character.getNumericValue() method

• Sum up all the digits found in the string

OOPs concepts used in the framework include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance is used to create a parent-child relationship between classes. For example, a base class 'Page' can be inherited by 'HomePage' and 'LoginPage' classes.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass. For instance, a 'click' method can be implemented different...read more

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example of compile-time polymorphism: function overloading in Java.

• Example of runtime polymorphism: method overriding in Java

Cucumber options are configuration settings used in Cucumber to customize test execution.

• Cucumber options can be used to specify features, tags, formats, and more in the test execution

• Examples include specifying tags to run specific scenarios, setting output formats for test reports, and defining feature files to run

In my project, I have used Oops concepts like Inheritance, Polymorphism, Encapsulation, and Abstraction.

• Inheritance: Reusing code and creating a hierarchy of classes.

• Polymorphism: Ability to present the same interface for different data types.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Abstraction: Hiding the implementation details and showing only the necessary features.
