- Write a program that asks the user to input two integers a and b. Pass the two input integers to method called “createArray”. Then create an array that has all integer from a to b. Return the array to main method and print the array from the main method
Example 1:
Input two numbers: 6 2
Array is [6, 5, 4, 3, 2]
Example 2:
Input two numbers: 4 8
Array is [4, 5, 6, 7, 8]
- Pass the above array as a parameter to a method called average and return the average and print it out in the main method.

- 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…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 10.0Write a method where you’re going to read an array and print second smallest value in that array.You may use the following header for this method:public static void secondSmallest(int[] array)Example:Input array elements: {1, 4, 3, 9, 2, 3, 4}Output:Second Smallest Value:2
- JAVA PROGRAM Write a program that asks the user to input two integers a and b. Then create an array that has all integer from a to b. Print out the array. (Don’t forget to consider the situation of a=b, a<b, and a>b.) Example 1: Input two numbers: 6 2 Array is [6, 5, 4, 3, 2] Example 2: Input two numbers: 4 8 Array is [4, 5, 6, 7, 8] Pass the above array as a parameter to a method called average and return the average and print it out in the main method. (Do not use Math library to get the average.)Write a method to read numbers from the keyboard into an array. Stop reading when the user enters the sentinel value -999. Return the number of values that were read. Do not put the sentinel in the array and do not include it in the number of values entered. Print an error message and stop reading if the user tries to enter more values than the array can hold.Write a method to print out the numbers in the array. Make sure the method only prints the array positions that were filled with the user's input. Print one number on each line.Write a method called zeros to return the number of entries in the array which contain zero.Write a method called replace which includes the parameters before and after, which are both integers. The method will change every array entry that contains the value before to contain the value after. For example, if the array contains {10,20,30,40,20,50}, before is 20 and after is 1, the array should be changed to {10,1,30,40,1,50}.Write a method called positive…Needs to be written in java: 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).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())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). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a…
- Write a method, given a String array, will return a new copy of the array but with all of its elements in lower case. (Use Java) (Hint: You can use the method toLowerCase()) For example, if the method receives the following String array: {"stone", "Bronze", "IRON", "Industrial", "INFOrmation"} It should return a new String array with the following values: {"stone", "bronze", "iron", "industrial", "information"}JAVA: Below is a method intended to modify the input array by doubling each element and a main method that calls it. What does this code print out? If the method does not do what is intended, what needs to be modified?Needs to be written for Java and in one program: Write a program that asks the user to input two integers a and b. Pass the two input integers to method called “createArray”. Then create an array that has all integer from a to b.

- in java write a method that given an integer array, computes and returns the sum of all negative numbers in the array. Example: array: 13, -2, 3, -4, -5 result: x= -2 -4 -5; x= -11/*In this program you need to implement four methods with the following signatures:printArr(int[] a)add(int[] a, int[] b)subtract(int[] a, int[] b)negate(int[] a) 1. Method printArr(a) should print out all elements of a given int array in one line. 2. Method add(a, b) should take two int arrays (assume they have the same length) and return a new array each element of which will be the sum of the corresponding elements in a and b 3. Method subtract(a, b) is similar to add(), except it returns (a - b) array 4.

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.
