Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Question

a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b.

Example 1:

a = 6, b = 2

Array is [6, 5, 4, 3, 2]

Example 2:

a = 4, b = 8

Array is [4, 5, 6, 7, 8]

Example 3:

a = 4, b = 4

Array is [4]

b). In main method, you should ask the user to input two integers a and b.

Then call method createArray and print out the array.

class Main {

public static int[] createArray(int a, int b) {

}

public static void main(String[] args) {

}
}

TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).
Java: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting. Paste your code into the placeholder at the top of the file. Review the Homework FAQ page, which contains instructions and a video of how to use the provided file.

Question: 1. Write a method that has an int parameters. Creates an array of integers of that size. Reads in values for the array from the user. Returns the newly created array. 2 Write a method that given an array of integers.returns the index of the smallest integer.
JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.
1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
4. write a method called secondLargest that takes an array of integers and returns the second largest element in the array. Sample code Int [] x = {1,2,3,4,5}; System.out.println (secondLargest (x)) ; Int[] x = {500,2,3,4, 5}; System.out.println (secondLargest (x)); Sample output 4 5
Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Write a java application which initializes an array with ten random integers between 1 and 6. Write two methods: 1. arraySwap: this method should accept an integer array and swap the first and the last item. 2. findMinimum: this method should accept the array and return the minimum value of that array You should comment and follow javaDoc for both methods. Your main method should test each of these methods.
Write a method with header static void DisplayIntArray(int[] numbers). The first argument is an array of ints. There is no return value. This method displays all the elements of the argument on a single line. Each item will occupy three columns.Call this method from main with a suitable argument. Write a method with header static int[] GenerateRandomIntArray(int numberOfItems, int largestValue). The first argument is an int indicating the number of elements that will be present in the return array. The second argument is an int representing the largest item in the array. The returned value is an array of integers. This method does the following: Declare and initialized a variable of type Random (Random generator = new Random();) Declare an array of type int (you may call it result) Allocate storage for the correct number of items Using your favorite looping statement, assign a random integer to each element of the array (result[i] = generator.Next(largestValue);) In your…
For Beginners Java: Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input. You need to store these scores in an array. You can assume the maximum number of scores the user may enter is 50. However, you need to keep track of the actual number of scores entered. Write 2 methods: 1. calculateAverage(): this method takes the list of scores and return the average score. 2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100). The main program reads the input and calls these methods and print the results. Please make sure you write a comment line to document what your method does.
Exercise (Array and Method): Write a method called arrayToString(), which takes an int array and return a String in the form of {a1, a2, ..., an}. Take note that there is no comma after the last element. The method's signature is as follows: public static String arrayToString(int[] array) Also write a test driver to test this method (you should test on empty array, one-element array, and n-element array). Notes: This is similar to the built-in function Arrays.toString(). You could study its source code. Exercise (Array and Method): Write a boolean method called contains(), which takes an array of int and an int; and returns true if the array contains the given int. The method's signature is as follows: public static boolean contains(int[] array, int key) Also write a test driver to test this method. Exercise (Array and Method): Write a method called search(), which takes an array of int and an int; and returns the array index if the array contains the given int; or -1 otherwise. The…
