How to Write Global Parameters with Java Code

This video tutorial explains how to manage global environmental values in Java test cases using properties files. It covers creating properties files, reading and modifying values, and writing back changes. The tutorial demonstrates using Java classes like Properties, FileInputStream, and FileOutputStream to handle these tasks, providing a practical approach to managing test environments and configurations.

Why is it beneficial to set global values for browser and URL in Java test cases?

• To reduce the number of test cases

• To ensure all tests run in the same environment

• To make the code more complex

• To avoid using properties files

What is the purpose of creating a properties file in Java?

• To store global values for easy access

• To compile Java code

• To execute test cases

• To debug Java applications

Which Java class is used to read values from a properties file?

• Scanner

• BufferedReader

• Properties

• FileReader

How can you retrieve a value from a properties file in Java?

• Using the readLine method

• Using the getProperty method

• Using the fetchProperty method

• Using the getValue method

What happens when you modify a property value at runtime in Java?

• The value is ignored

• The value is updated in the properties file

• The value is deleted from the properties file

• The value is updated only in the code

Which method is used to update a property value in the code?

• setProperty

• updateProperty

• changeProperty

• modifyProperty

What is the purpose of the FileOutputStream class in Java?

• To read data from a file

• To write data back to a file

• To delete a file

• To execute a file

Which method is used to write updated values back to a properties file?

• write

• save

• store

• update

What is the difference between load and store methods in Java properties?

• Load reads data, store writes data

• Load writes data, store reads data

• Both read data

• Both write data

Why is it important to use the store method after modifying properties in Java?

• To compile the Java code

• To delete the properties file

• To execute the test cases

• To ensure changes are saved to the file
