iWriting code in Java to finish the following Programming Exercises.

Task $1$:

$($Maximum element in ArrayList$)$ Write the following method that returns the maximum value in an ArrayList of integers. The method returns null if the list is null or the list size is $0.$

public static Integer max$($ArrayList list$)$

Write a test program that prompts the user to enter a sequence of numbers ending with $0$ and invokes this method to return the largest number in the input.

Task $2$:

$($Largest rows and columns$)$ Write a program that randomly fills in $0$s and $1$s into an n$-$by$-$n matrix, prints the matrix, and finds the rows and columns with the most $1$s$.$

$($Hint: Use two ArrayLists to store the row and column indices with the most $1$s$.)$

Here is a sample run of the program:

Enter the array size n: $4[$Enter$]$

The random array is

$0011$

$0011$

$1101$

$1010$

The largest row index: $2$

The largest column index: $2,3$
