Event handler:
An event handler is a module is implemented in python program that executes automatically when a particular event has occurred.
- If user need a program to execute an operation at that time a particular event occurs, user must create an event handler that reply at that time of event takes place.
- Event can be pressing the key or mouse operation by the user. To deal this type of operation is considered as event handlers.
- If the defined event occurs, then call the handler function with help of object of event.
- The following format is a general format for event handler.
Module ComponentName_EventName()
Statement
End Module
Where,
- ComponentName indicates the component name.
- EventName indicates event name which occurred.

- Write a complete Java program named FindSumAndAverage that performs the following tasks in 2-D array: Main Method: a. The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns. b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9. c. The main method then calls another method named printMatrix() to display the matrix in a matrix format. d. The main method also calls a method named findSumAndAverage() which: • Receives the generated matrix as input. • Calculates the sum of all elements in the matrix. • Calculates the average value of the elements in the matrix. • Stores these values (sum and average) in a single-dimensional array and returns this array • e. The main method prints the sum and average based on the result returned from findSumAndAverage()).
