1 Write a method that is passed an array as a parameter The

1) Write a method that is passed an array as a parameter. The method should set all of the values in this array to 7.2. The method should return the size of the array.

2)Write a method that prints all the values in a 2-dimensional array that it receives as a parameter. Assume that the array is an array of integers.
