Assignment $01$

$**$Please give proper user prompt

Write a Java code from the above UML diagram where the display function displays all the information of

the class. The name attribute contains the name of the book and the year is the year of publishing the

book. In the 'calculate' method, you need to create a $2$D array and show the sum of the diagonal. For

example :

If the array is: $\{[1,3,4],[5,0,6],[9,7,4]\}$

The result will be $5=(1+0+4).$

Show two objects of the class $($at least one object should be user input$).$

Create another class "Matrix" similar to the Mathbooks class but you need to modify the 'calculate $"$

method so that it can create two $2$D arrays and the multiplication of them and show the resulting matrix

after multiplication. Both $2$D arrays should be user input. You need to construct one Matrix object and

show the resulting matrix.

Ask the user to enter a single integer value$($n$)$ and write a Java method "summation" that

returns the sum of every multiple of $3$ from $1$ up to the provided integer $n.$ If the user inputs $17$ then

the sum of $3+6+9+12+15$ is $45\mathrm{.}45$ will be the output.
