Q1) How would you declare an array of doubles called myDoubles? Arrays can be initialized in one of two ways. In one method, the array elements are placed in a list enclosed in curly braces after the array name definition. For example, the code below creates an array of ints with 3 elements: 1, 2 and 3. int[] a = {1, 2, 3, 4}; We can also initialize an array with a new construct, indicating how many elements we want...

Define a two-dimensional int array which has 5 rows and 3 columns. The elements in array is randomly initialized (using Math.random()). Write a method to find the maximum value in this two dimensional array; Write a method to find the average value in the array; Write a method to count how many elements are smaller than average; Write a method to copy contents in a two-dimensional array to a one-dimensional array. The method will return this one-dimensional array. Method is...

In java, write method, shuffle, which accepts an array of int, creates a copy of the formal parameter, shuffles the copy, then returns the copied, shuffled array, leaving the formal parameter unchanged. Shuffling is a process of swapping each element of array with another element randomly chosen from the array. For testing the shuffle method have main call shuffle, repeatedly having it shuffle its previously returned array until the returned (shuffled) array is identical (equal) to the original array that...
