Question

Write a Java code to create a recursive function that performs an element-by-element operation on two one-dimensional arrays of identical size provided by the user. The operation should be a parameter of type character with a value in the set {‘+’, ‘-‘, ‘*’, ‘/’}. The arrays must be populated with random integers in the range [-10, 10]. For example, given A = [3, 1, -2] and B = [9, -7, -4], both of size 3, and the operation ‘+’, the resulting array is equal to [12, -6, -6].

Write a Java program that declares an array to hold 12 integers. The contents of the array should be the values 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24. Use a for-loop to initialize the contents of the array to these values. After initializing the array to these values, the program should display the contents of the array. Suggested output: The contents of the array are: Index Value 0 2 1 4 Etc.....

Write a Java program that declares an array of size 10, using a constant for the size. Then, using a loop prompt the user to enter 10 floating point values and assign those values to the array. Display the contents using a for loop to go through the array and print out the contents until the end of the array has been reached.

00:01 In this problem, we're asked to create an integer array, fill it with multiples of two, and then print it back to the user.
00:09 So we start by creating the array.
00:13 So it's an integer array, so you do int, and then name of the array.
00:17 It's called an int array.
00:19 Square brackets equals new, int, and then it gives us that the size of the array is 12, so make sure you put that there.
00:26 And then to initialize the contents, it tells us we need to use a for loop.
00:31 So do 4 int i equals 0, well i is less than 12, i plus plus.
00:37 So this basically goes through each value of the array, starting from the index of 0 and then increasing sequentially here...
