Write a static method called flip2 that takes an ArrayList of Strings as a parameter and then flips each successive pair of values in the list. For example, suppose that a variable called list stores the following sequence of values: ["aa", "bb", "cc", "DDD", "happy", "snow"] and we make the following call: flip (list); Afterwards the list should store the following sequence of values: ["bb", "aa", "DDD", "cc", "snow", "happy"] If the list has extra values that are not part of a pair, those values are unchanged. For example, if the list had instead stored: ["aa", "bb", "cc", "DDD", "happy", "snow", "hometown"] The result would have been: ["bb", "aa", "DDD", "cc", "snow", "happy", "hometown"]

Write a public static method named allLessThanMean that will take an ArrayList<Integer> as an argument. This method will return an ArrayList<Integer>. When called and passed anArrayList, this method will return an ArrayList containing all the elements in the argument ArrayList that are less than the average of all the values in the argument ArrayList. The values in the returned ArrayList must be in the same order as they are in the argument ArrayList. Here are some examples: Example 1 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {1, 2, 3, 4, 5}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {1, 2} Example 2 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {3, 7, 6, 2, 9, 0, 4, 8}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {3, 2, 0, 4} Example 3 Given: ArrayList<Integer> myList = new…

java Create a static method that: is called appendPosSum returns an ArrayList of Integers takes one parameter: an ArrayList of Integers This method should: Create a new ArrayList of Integers Add only the positive Integers to the new ArrayList Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged. public static void main(String[] args) { Scanner in = new Scanner(System.in); int size = in.nextInt(); ArrayList<Integer> list = new ArrayList<>(); for(int i=0; i < size; i++) { list.add(in.nextInt()); } System.out.println(appendPosSum(list));
Write a program that reads a list of integers, and outputs whether the list contains all multiples of 10, no multiples of 10, or mixed values. Define a method named isArrayMult10 that takes an array as a parameter, representing the list, and an integer as a parameter, representing the size of the list. isArrayMult10) returns a boolean that represents whether the list contains all multiples of ten. Define a method named İsArrayNoMult10 that takes an array as a parameter, representing the list, and an integer as a parameter, representing the size of the list. İsArrayNoMult10() returns a boolean that represents whether the list contains no multiples of ten. Then, write a main program that takes an integer, representing the size of the list, followed by the list values. The first integer is not in the list. Assume that the list will always contain less than 20 integers. Ex: If the input is: 5 20 40 60 80 100 the output is: all multiples of 10 Ex: If the input is: 5 11 -32 53 -74 95 the…
Write a static method named "bigBeforeSmall" that accepts an array of Strings as a parameter and rearranges its elements so that longer Strings appear before shorter Strings. For example, if the following array is passed to your method: String[] numbers = { "one", "twelve", "three", "four", "fourteen", "six" }; Then after the method has been called, one acceptable ordering of the elements would be: ["fourteen", "twelve", "three", "four", "one", "six" ] The exact order of the elements does not matter, so long as all longer Strings appear before all shorter Strings. Another acceptable order would be: ["fourteen", "twelve", "three", "four", "six", "one" ] Do not make any assumptions about the length of the array or the range of values it might contain. For example, the array might contain empty Strings (length zero), or all Strings could have the same length. You may assume that the array is not null (empty). Hint: This is actually a sorting problem. In BubbleSort you tested pairs…
