a) Write a Java program that counts and outputs the number of times a zero occurs in an array of maximum 50 integers. Write some array examples to test your program.

b)Write a method sumArrays that receives two one-dimensional arrays list1 and list2 of integers as parameters and returns the sum of the all of the values in list1 plus the sum of all of the values in list2. Now write a main program to call sumArrays. Pass arrays arr1 and arr2 as arguments, and print the sum that is returned by sumArrays.

c) Write a Java program to find and display the largest and smallest values in a two- dimensional (m x n) integer array.

Please, seperate them so I can know which is which. Thank you!
