💡 Hint

Common Mistakes

Using 'read' instead of 'load' causes a compile error.

The load method reads the properties file into the Properties object.

💡 Hint

Common Mistakes

Using 'get' causes a compile error because Properties does not have a 'get' method.

The getProperty method retrieves the value for the given key from the Properties object.

hard

Fix the error in the code to properly close the FileInputStream.

Selenium Java

FileInputStream fis = new FileInputStream("config.properties");
try {
    prop.load(fis);

💡 Hint

Common Mistakes

Using 'shutdown' or 'dispose' causes compile errors because these methods don't exist for FileInputStream.

The close method properly releases the resource held by FileInputStream.

4fill in blank

hard

Fill both blanks to create a Properties object and load the file safely using try-with-resources.

Selenium Java

try (FileInputStream fis = new FileInputStream("config.properties")) {
    Properties [1] = new Properties();
    [2].load(fis);
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different variable names causes confusion and errors.

Using the same variable name prop for the Properties object is clear and consistent.

5fill in blank

hard

Fill all three blanks to read a property 'browser' and print it.

Selenium Java

Properties prop = new Properties();
try (FileInputStream [1] = new FileInputStream("config.properties")) {
    prop.load([1]);
    String browser = prop.[2]("browser");
    System.out.println("Browser: " + [3]);
}

💡 Hint

Common Mistakes

Using wrong variable names or method names causes errors or wrong output.

The FileInputStream variable is fis, the method to get property is getProperty, and the variable to print is browser.
