Write java methods to do these tasks: a. Move even elements to the front, if not then preserving the order of the elements. Return true if all elements in array are identical. b.Remove the middle element if the array length is odd, or the middle two elements if the length is even. **Find the mean of the values in an array **Find the second-largest element in the array. **Find the median value of the values in an array

JAVA: Suppose that we have a sorted int array called x, with n elements in it and some room to add more elements. Write the code segment that would add a new item, called target, to the array, so that the array will still be sorted once you are done.

Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).

Implement an empty integer array of capacity 5. a) Use a loop to input values from the console into the array. b) Use a loop to determine the smallest element in the array. c) Use a loop to determine the largest element in the array. d) Use a loop to output the array. e) Output the smallest and largest elements. Example Output [0] = 4 [1] = 24 [2] = 123 [3] = 54 [4] = 3 Array: 4 24 123 54 3 Max: 123 Min: 3 programming language is c++ pleasw do it in a easy way
