Define a static void method, which receives as an parameter an array of salaries (of type double) and increases them as follows • salaries <$ 800 - by 10% • 800 <= salaries <= $1500 - by 5% • salaries over $1,500 - by 3% In the test function, define an initialized array of salaries and display it. Call the written method and display the array again.
Use the java code below and integrate additional method to: Print the minimum values of each row and of each column. public class ArrayOperations2D {public static int[] findRowMax(int[][] anArray) {int[] max = new int[anArray.length];for (int i = 0; i < anArray.length; i++) {int largest = anArray[i][0];for (int j = 0; j < anArray[i].length; j++) {if (anArray[i][j] > largest) {largest = anArray[i][j];}}max[i] = largest;}return max;}public static int[] findRowSums(int[][] anArray) {int[] rowSums = new int[anArray.length];for (int i = 0; i < anArray.length; i++) {int sum = 0;for (int j = 0; j < anArray[i].length; j++) {sum += anArray[i][j];}rowSums[i] = sum;}return rowSums;}public static int[] findColumnMax(int[][] anArray) {int[] max = new int[anArray[0].length];for (int j = 0; j < anArray[0].length; j++) {int largest = anArray[0][j];for (int i = 0; i < anArray.length; i++) {if (anArray[i][j] > largest) {largest = anArray[i][j];}}max[j] = largest;}return…
Write the equals method for Circle2 which returns true when the radius and the color are the same as the parameter’s radius and color. The TestCircle2, Circle2 and GeometricObject2 classes are given as follows. public class TestCircle2 { public static void main(String[] args) { Circle2 c1 = new Circle2(2.3, "red"); Circle2 c2 = new Circle2(5.6, "white"); Circle2 c3 = new Circle2(2.3, "red"); System.out.println("c1 equals c2: " + c1.equals(c2)); System.out.println("c1 equals c3: " + c1.equals(c3)); System.out.println("c2 equals c3: " + c2.equals(c3)); } } class Circle2 extends GeometricObject2 { private double radius; public Circle2() { } public Circle2(double radius) { this.radius = radius; } public Circle2(double radius, String color) { this.radius = radius; setColor(color); } /** * Return radius */ public double getRadius() {…
Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.Relevant geometry equations:Volume = base area x height x 1/3Base area = base length x base width.(Watch out for integer division). import java.util.Scanner; public class CalcPyramidVolume { public static double calcBaseArea(double baseLength, double baseWidth) { return baseLength * baseWidth; }/*Your solution goes here*/ public static void main (String [] args) { Scanner scnr = new Scanner(System.in); double userLength; double userWidth; double userHeight; userLength = scnr.nextDouble(); userWidth = scnr.nextDouble(); userHeight = scnr.nextDouble(); System.out.println("Volume: " + calcPyramidVolume(userLength, userWidth, userHeight)); }}
You can just provide code as you don't have required utility class, Please provide explanation and comments for code : Write a static method asciiGraph(), to display a “graph” of ASCII values of a String. 2.The method has a single String parameter str, and returns nothing (void).3.The method loops through all characters in str, and for each displays a line of *s on a row equal to the ASCII/Unicode integer value of the character being examined (see example).Hints:1. recall the String methods .charAt() and .length(), and casting a char with (int) directly returns the int ASCII/Unicode value2. to produce the line of *s, call the method starLine() from the Exam utility class3. in the output capture document, consider reducing the font size to 7 or 8 point to have each row of *s on a single line Consider the strings “Ab C” and “TED 99”, that are composed of:A displays 65 stars (*), since Unicode 65 = 'A'b 98 stars (*), since Unicode 98 = 'b'space 32 * , since Unicode 32 = ' ' (the space)C…
In java, Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.
Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. calcPyramidVolume() calls the given calcBaseArea() method in the calculation.Relevant geometry equations:Volume = base area x height x 1/3Base area = base length x base width.(Watch out for integer division).

In Java In the Jackal class, complete the public method definition for setAge() with the integer parameter customAge. Ex: If the input is black Mia 3, then the output is: Color: black Name: Mia Age: 3
Given an integer N, implement a Static method 'solution' with return type as 'void' in class 'ProblemSolution' displays N for N times. Input 7 Output 7 7 7 7 7 7 7 Where, There must be single space between 2 numbers. There should not any space after the last number. Assume that, N is within the range [0 to 10000].
Validate that the following code, which adds the methods var() and stddev() to Accumulator, computes both the mean and variance of the numbers presented as arguments to addDataValue(): public class Accumulator{ private double m; private double s; private int N; public void addDataValue(double x) { N++; s = s + 1.0 * (N-1) / N * (x - m) * (x - m); m = m + (x - m) / N; } public double mean() { return m; } public double var() { return s/(N - 1); } public double stddev() { return Math.sqrt(this.var()); }} This implementation is less susceptible to roundoff error than the straightforward implementation based on saving the sum of the squares of the numbers.
