related classes and interfaces. It provides a hierarchical structure and helps prevent
naming conflicts between classes.
94. What is the purpose of the "import" keyword in Java?
The "import" keyword in Java is used to import classes, interfaces, or packages into a
source file. It allows using classes from other packages without specifying their fully
qualified names.
95. What is the purpose of the "throw" keyword in Java?
The "throw" keyword in Java is used to manually throw an exception. It is typically used
when a program encounters an error or exceptional situation that cannot be handled,
and the control should be transferred to an exception handler.
96. What is the purpose of the "throws" keyword in Java?
The "throws" keyword in Java is used in method declarations to specify that a method

exception or propagate it further.

the exception, and the "finally" block contains cleanup code that is executed
regardless of whether an exception occurs or not.

returns a boolean value indicating whether an object is an instance of a particular class
or implements a specific interface.

The "break" statement in Java is used to terminate the execution of a loop or switch
statement. It allows exiting a loop prematurely or skipping the remaining cases in a
switch statement.

The "continue" statement in Java is used to skip the current iteration of a loop and
continue with the next iteration. It allows skipping certain iterations based on specific
conditions without exiting the loop entirely
