Such wasted space is an imperfection she cannot bear. As her oldest and dearest friend this worries you greatly. If you were a doctor you might try to find a cure to her sickness, but you are a programmer. A program must be written to alleviate her pain! For any array given that has empty slots create a new array that is perfect. Unused slots will have a value of 0. All unused slots are guaranteed to be at the end of the array. There will never be unused slots in the middle. java.util.Arrays has been enabled. Examples: makePerfect({1, 1, 4, 5, 6, 0, e, e, 0}) -> {1, 1, 4, 5, 6} makePerfect({1, 3, 4, 2, 6, 0, e, e, 0}) -> {1, 3, 4, 2, 6}JAVA PROGRAM Chapter 7.

This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array.

Create an Array to store two Employee objects d.

What to return? - For each integer value in 'indices', if it is a valid index for input array ssa', then use it to index into 'sea' and include the result in the output array. For example: Say ssa' is (23, 46, 69} and indices' is (2, -1, 0, 3, 0, 2} (where indices -1 and 3 are invalid, so only indices 2, 0, 0, 2 are used) Then the method should return (69, 23, 23, 69} Note: Order of elements in the output array corresponds to the order in which valid indices in the 'indices' array are arranged. That is, the output array may be empty if the input array sea is empty, or if the input array indices does not contain any valid indices.

The array will have at least 2 elements in it public class Class1 { public static int endSum(int[] values) { //Enter code here } } Use Java and show output screenshot and implementation screenshot Please don't copy from other websites.Part 1: Randomizing an Array In this problem you will write a program that will randomize the elements of an array created by the user. 1. Prompt the user to enter an integer, then asks the user to enter that many values. Store these values in an array and print the array. Then re-shuffle the array elements so randomly. Do not just randomize the order in which they are printed; actually change the way they are stored in the array. Do not create a second array; just rearrange the elements within the array you have. (Hint: Swap elements that need to change places.) When the elements have been randomized, print the array again. 2. Create another version of your program that applies the following modification to the randomization process: elements that have been already swapped should not be swapped again. Example: if element 1 was swapped with element 10, when the 10 th element is reached it should not be swapped again. Yet if the 2 nd element is reached it can be swapped with the 10o the…JAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method. Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2 Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average. If the number of elements in an array is odd don't modify the last number of the array. Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…
