After finding the number of iframe in a webpage, we will use the index method to find 4th iframe -

driver.switchTo().frame(4);

It can also be searched using ID as well.

1. Private - If a variable is declared as Private, then it can only be used by the same class and it cannot be accessed outside that class. Classes and interfaces cannot be declared private.
2. Public - Methods/ Variables declared with public access modifier can be accessed by all other classes. 
3. Protected - Protected variables can be accessed by the classes of the same package and even sub-classes of a different package. Although, the access modifier cannot be used for classes and interfaces.

• What are the different data types in Java? - Java is a statically-typed language Which means all variables must be declared first before running a program. There are 8 different types of primitive data types used in Java - int, boolean, short, long, double, float, char and byte.
