Q1. Write the following method that returns thesmallest element in an ArrayList:public static <E extends Comparable<E>> E min(ArrayList<E> list).
Min Heap of Candy — Add and Remove
Using the provided code (Question04.java and Candyjava), write the add and remove methods for a min heap of Candy using an array implementation. Make sure to include all provided files in your project and write your solution in the file "Question04.java". This method should preserve the properties of a min hap, and the candies are compared based on their weight. This value can be accessed through its accessor.
Solution Tests:
• Does the solution compile?
• Does the solution have your name in the comments?
• Does the solution have a high-level solution description (150-300 words) in the comments?
• Does the method preserve the properties of a Min Heap?
• Does the output match the following?
Testing the Add Method
Candy Weight: 10.0,
Candy Weight: 40.0,
Candy Weight: 20.0,
Candy Weight: 50.0,
Candy Weight: 60.0,
Candy Weight: 80.0,
Candy Weight: 30.0,
Candy Weight: 100.0,
Candy Weight: 70.0,
Candy Weight: 90.0,
Testing the Remove Method
Candy Weight:…
Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different.
For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).

The delimiters are balanced when both of the following conditions are satisfied; otherwise, they are not balanced. When traversing the ArrayList from the first element to the last element, there is no point at which there are more close delimiters than open delimiters at or before that point. The total number of open delimiters is equal to the total number of close delimiters.
