Write a method that returns the range of an array of integers. The range is the difference between the highest and lowest values in the array. The signature of the method should be as follows

/*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. Method negate(a)takes an int array and returns a new array in which every element is multiplied by -1. */ public class ArrayOperations{ public static void main(String[] args){ //The main only has the testing code. //You don't have to change it. int [] a = { 1, 2, 3, 4, 5}; int [] b = {10, 1, 3, 5, 7}; System.out.print("a = "); printArr(a);//Should print each element of a (in one line) System.out.print("b = ");...

x = 3 + numbers[3]++; System.out.println(x); QUESTION 2: Class Rectangle has two data members, length (type of float) and width (type of float). The class Rectangle also has the following: //mutator methods void setlength (float len) } //B. length = len; H accessor methods float getLength() I return length; The following statement creates an array of Rectangle with size 2: Rectangle[] arrayRectangle= new Rectangle[2]; Is it correct if executing the following statements? What is the output? If it is not correct, write the correct one arrayRectangle. setLength (12.59); System.out.printin[rectangle Set.getLength()); arrayRectangle[1].setLength(4.15); System.out.println(arrayRectangle[1].getLength()): QUESTION 3: Use the following int array int[] numbers = { 42, 28, 36, 72, 17, 25, 81, 65, 23, 58} -Open file data.txt to write. to write the values of the array numbers to the file with the y numbers to get the values

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

PART A: Note: The following code is written only in main -- you assume there is an array bag and you are not adding any methods to that bag. Write the main program to create two array bags of type string. Place 5 strings of your choice in the first bag and 5 strings (of your choice) in the second bag. Your program must:1) determine if there are any strings in the first bag that appears in the second bag as well. If there are, print there are repeated strings. Else print the bags have unique values. 2) Print the content of the both bags and if there are repeated values, print that value only once. PART B: Create two linkedBag objects of type string in main. Place 5 strings in the first bag and five strings in the second bag. Then your code must test if the two linkedBag objects are equal or not. You must traverse both linkedBags and test each items to see if they are the same. Then you must display a message saying the two linkedBags are the same or different. PART C: Write a...
