Question P Print person1's kids, call the incNumKids() method, and print again, outputting text as below. End each line with a newline. Sample output for below program with input 3: Kids: 3 New baby, kids now: 4 // ===== Code from file PersonInfo.java =====public class PersonInfo {private int numKids; public void setNumKids(int setPersonsKids) {numKids = setPersonsKids;} public void incNumKids() {numKids = numKids + 1;} public int getNumKids() {return numKids;}}// ===== end ===== // ===== Code from file CallPersonInfo.java =====import java.util.Scanner; public class CallPersonInfo {public static void main(String [] args) {Scanner scnr = new Scanner(System.in);PersonInfo person1 = new PersonInfo();int personsKid; personsKid = scnr.nextInt(); person1.setNumKids(personsKid); /* Your solution goes here */ }}// ===== end ===== Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this...

Problem 2: Complete the seperateDuplicateChars () method in Seperate Duplicates.java as follows: The method takes a String str as a parameter and returns a new String. The returned String should be exactly like str, but any identical characters that appear in a consecutive way must be separated by hyphens "-". You may ONLY use the following methods from the String class: charAt(), substring() and length(). Other than uncommenting the code, do not modify the main method in Seperate Duplicates.java. Sample runs provided below. Argument String str "Hello" "Bookkeeper" "Yellowwood door" "Chicago Cubs" Return String "Hel-lo" "Bo-ok-ke-eper" "Yel-low-wo-od do-or" "Chicago Cubs"

The following technique is used in a game of chess: canMoveTo(int x, int y), boolean. A method in the Piece class returns if the piece may travel to position (x, y). Describe how you would put this method to the test.

ISP- Java A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Your program must define and call a method: public static double stepsToMiles(int userSteps) Ex: Ex: If the input is: 8790 the output is: 4.40

In Java,thank you.

Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}

Need help with following Java method: import java.util.Scanner; import java.lang.Math; public class CosineFromScratch { /* The following code demonstrates how to estimate the cosine of a number. Your assignment is to migrate the calculation of the cosine into a new static method named cosine. The method should take one double input and return one double output. Make sure to call the method from main and set the variable estimate equal to the returned value. */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nGive me a number: "); double x = input.nextDouble(); //Trying to find cosine of this number double correct_cos = Math.cos(x); //START HERE: The following code goes into //the method. //Source for the following: //https://austinhenley.com/blog/cosine.html double num_terms = 10; int div = (int)(x / Math.PI); x = x - (div * Math.PI); int sign = -1; double estimate = 1.0;...

Using the code in the image provided: Implement a method called summation which adds two integers and returns their sum. INPUT: The first line of input contains an integer a. The Second Line of input containes and integer b. OUTPUT: Print the result which is the sum of a and b.

For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither. Don't forget to identify the last statement at the very bottom, Member m = new BoardMember();, as legal or illegal and widening or narrowing conversion.
