Write a helper method, with the signature eliminateZerosinArray[int[]): int[], that takes a single dimensional int array as an argument, and returns a new array that only contains the original values that are not equal to 0. The returned array may be the same size or smaller depending on whether there are values that are equal to 0 in the original array. You may only use standard intl| arrays to solve this.
Write a test program that creates two hexagons (5) and (10) and compares them using method compareTo(). Also, create array of four comparable hexagons with side value (4), (6), (10) and (2). Pass the array as parameter to method max. You should get the following result. Comparing two Hexagons -1 Max hexagon with biggest number of sides is 10.0
I need to write an array that can remove the middle element of an array if the array is odd length and remove the middle 2 elements if the array is of even length. my current method looks like this but does not work. Where am I going wrong? public static int[] removeMiddle(int[] values) { boolean even = false; int temp = values[0]; int temp2 = values[0]; int count = values.length; if( count % 2 == 0){ even = true; } for (int i = 1; i < values.length-1; i++){ if (even = true){ temp = values.length / 2; temp2 = values.length / 2 + 1; }else if(even = false){ temp = values.length / 2; values[temp] = values.length-1; count--; } } The problem is from Big Java 6th Edition.

Write a program in Java Eclipse that does the following:a) create a 2D Ragged array with columns and rows lengths of your choice. Fillit out with values (you can do it in one step or get an input from the user)b) print the elements of this array using 3 printing methods that we studied:- for loop- for-each loop- using Arrays classCreate a separate method for each such method.How do you call these methods? What do your methods return?

In F3, students will be tasked with taking input from a file to create an *Array* of FeetInches (2 parameters). When all the FeetInches have been stored, any FeetInches at least 1 foot will be converted and added to an *ArrayList* of Circles (one parameter). Students will then complete the compareTo method found in the Circle class, sort the ArrayList of Circles, and then output the radius' of the new circle. The first integer in the file input will tell us how many FeetInches objects will be made using the fileInput, and the numbers after are the data for those Objects. Use this first integer in your for Loops. A template with main, Circle, and FeetInches class, as well as the file input, is attached below. Please follow along with comments and reach out if you have any questions. package f3_template; public class Circle implements Comparable <Circle>{//attribute private int radius; //constructorspublic Circle(){radius=0;}public Circle(int r){radius=r;}//accessorspublic…

Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values. 1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below). Do not print the ‘trailing’ comma!!2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. Return largest integer and print from main(), not method.3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). Return new array of integers print from main(), not methodEXAMPLE OUTPUT:Enter…
Please help me solve this with java 1-method called printArray that takes an array of double values and prints the arrayelements on the same line with one space between each two elements, then prints a new line.2. A method called getRandomElement that takes an array of double numbers and returns a random element from the array.3. A method called shiftArray that takes a double value and an array of double values. The method must shift the array in its place to the right, and insert the double value at index 0. Note that this method must not create a new array, it must rotate the array in its place.For example, if the passed array is 6.5, 2.1, 5.8, 1.5, 8.9 and the passed double value is 3.3, after invoking the method the array must become:3.3, 6.5, 2.1, 5.8, 1.54. A method called occurrences that takes a double value and an array of doubles as parameters, and returns the number of occurrences of the double value in the array.For example, if the double number 4.1 and the array {1.5,…
Define an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…
