The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

//This initializes a boolean variable

boolean isNeg = true;

//This iterates through the array

for (int i = 0; i < myArr.length; i++) {

//If the array element is 0 or positive

if (myArr[i] >= 0) {

//Then the boolean variable is set to false

isNeg = false;

//And the loop is exited

break;

}

//This returns true or false

return isNeg;

}

There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in in

Dafna1 [17]

Answer:

import java.util.Scanner;

public class InchConversion

{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter inches: ");

double inches = input.nextDouble();

inchesToFeet(inches);

inchesToYards(inches);

}

public static void inchesToFeet(double inches){

double feet = inches / 12;

System.out.println(inches + " inches = " + feet + " feet");

}

public static void inchesToYards(double inches){

double yards = inches / 36;

System.out.println(inches + " inches = " + yards + " yards");

}

Explanation:

In the inchesToFeet() method that takes one parameter, inches:

Convert the inches to feet using the conversion rate, divide inches by 12

Print the feet

In the inchesToYards() method that takes one parameter, inches:

Convert the inches to yards using the conversion rate, divide inches by 36

Print the yards

In the main:

Ask the user to enter the inches

Call the inchesToFeet() and inchesToYards() methods passing the inches as parameter for each method
