Complete the following code for sorting an array of objects of the described ??????? class. The method should sort the elements of the array according to a decreasing order of the averages of the students. public class practice { public void sort (student[] aArray) { practice student; int chosenIndex = 0; for ( int x = 0; x < aArray.length - 1; x++) { chosenIndex = x; for (int y = x + 1; y < aArray.length; y++) { if (____) chosenIndex = y; } if (chosenIndex != x) { temp = ____; aArray[x] = ____; _____; } }}
What sort algorithm is implemented in the sortArray2 method in the following program segment? *
Assume that the following program segment is executed. What is the last element of testArray2 after the execution of the statement sortArray1(testArray2);? *
8. Repetition Use Python Language Write a method that takes in an array as a parameter and counts the repetition of each element. That is, if an element has appeared in the array more than once, then its 'repetition' is its number of occurrences. The method returns true if there are at least two elements with the same number of 'repetition'. Otherwise, return false. Input: {4,5,6,6,4,3,6,4} Output: True Explanation: Two numbers repeat in this array: 4 and 6. 4 has a repetition of 3, 6 has a repetition of 3. Since two numbers have the same repetition output is True. Input: {3,4,6,3,4,7,4,6,8,6,6} Output: False Explanation: Three numbers repeat in this array:3,4 and 6 .3 has a repetition of 2, 4 has a repetition of 3, 6 has a repetition of 4. Since no two numbers have the same repetition output is False.

DNA Max Write code to find which of the strands representing DNA in an array String[] strands representing strands of DNA has the most occurrences of the nucleotide represented by parameter nuc. Complete the definition of the class DnaMax and method definition maxStrand shown below. If more than one strand has the same maximal number of the specified nucleotide you should return the longest strand with the maximal number. All DNA strands have different lengths in this problem so the maximal strand will be unique when length is accounted for. Return this uniquely maximal strand. Each String representing a DNA strand will contain only cytosine, guanine, thymine, and adenine, represented by the characters 'c', 'g', 't', and 'a', respectively. If no strand in the array contains the specified nucleotide return the empty string "". public class DnaMax { public String maxStrand(String[] strands, String nuc) { // fill in code here } } Constraints strands will contain no more than 50 elements,…

java getDup accepts an array and returns an int. If there is any element is duplicated, the method counts how many of those present in the array. Example : getDup(["1","2","aa"',"1"]) returns:2 ("1" is duplicated and there are two "1"s so return is 2) class Main { public static int getDup(String[] r) { } public static void main(String[] args) { Scanner in = new Scanner(System.in); String [] strs = new String[in.nextInt()]; for(int i=0; i < strs.length; i++) { strs[i] = in.next(); } System.out.println(getDup(strs)); } } hint: you will need a nested array the will run on the array we get from the method argument. inside the nested loop you will need to check if the main array element is equal to the current

Searching and sorting in Java programming: Write a method remove, that takes three parameters: an array of integers, the length of the array, and an integer, say removeItem. The method should find and delete the first occurrence of removeItem in the array. If the value does not exist or the array is empty, output an appropriate message. Note: after deleting the element, the array size is reduced by 1. You may assume that the array is unsorted. Thank you. I took Java in 2012 and 2013, and we didn't go too deep in this cocept..just a little bit in the Arrays chapter. i wanted to try something ne! Thank you!
