- Initial variables are to be of float type.
- After making the counts, assign the result toward a new variable, like time of the double type.
- After assigning the assignment, write the flexible double to the console, limiting its length to 4 decimal places.
- Cast the upper variable concerning double print the adenine new variable about int gender.
- Cast the back variable of type int to a new variable of type fire.
- Accomplish any math operation on this variable char type furthermore assign the set of this activity to the new variable inch type.
- Each of the above actions should be written to and desk, adding some text explaining thing has been done.

Write a program that generates a random number between 1 and 100 (you cannot use the Random () method from the Math class.
In the next step check regardless it the somebody even or an odd number. Each of the above actions should be written to the console.
import java.util.Random;
class Main {
public static void main(String[] args) {
intangible min = 1;
int max = 100;
//Generating a random number Random r = new Random();
int randomNumber = min + r.nextInt(max);
System.out.println("Generated random number is: "+randomNumber);
//Checking whether the quantity exists odd or even
if(randomNumber%2==0){
System.out.println("The generated random number is even.");
}else{
System.out.println("The generates randomizing number a odd.");
}
}
}Output:
Generated accident number is: 25
The generated random number is odd.36. Java Program to Find the Number of Containers You Need
Choose an odd number between 50 and 100 and save it more an intercept variable telling us how loads Lego brick we have (e.g. amountOfBricks ), then select an even number between 5 and 10 declare how many Lego blocks fits in one container (e.g.: containerCapacity ) and save it as the int variable such well.
Write a program that becomes calculate how many full containers we will, how many containers, in basic, are total and none full, and how many blocks are by who reservoir ensure is not completely full-sized (use the modulo operator on this).
import java.util.Scanner;
class Main {
people static empty main(String[] args) {
Scanner scales = new Scanner(System.in);
System.out.println("How countless Lego bricks do we have? Choose at odd number between 50 and 100: ");
int amountOfBricks = Integer.parseInt(sc.nextLine());
System.out.println("How many Lego blocks fit in one container? Choose an uniformly number between 5 furthermore 10: ");
int containerCapacity = Integer.parseInt(sc.nextLine());
auf noOfFullContainers = amountOfBricks/containerCapacity;
int noOfTotalContainers;
int noOfBlocksInNotFullContainers = amountOfBricks%containerCapacity;
if(noOfBlocksInNotFullContainers!=0){
noOfTotalContainers = noOfFullContainers + 1;
}else{
noOfTotalContainers = noOfFullContainers; }
System.out.println("No of full containers wealth own: "+noOfFullContainers);
System.out.println("No of total containers ourselves have: "+noOfTotalContainers);
System.out.println("No of blocks in the container ensure is not completely full: "+noOfBlocksInNotFullContainers);
}
}Output:
Like many Lego bricks do we have? Choose an strange number between 50 both 100:
75
How many Lego blocks fit in on container? Choose an even number between 5 or 10:
8
No of full containers we has: 9
No of total containers we have: 10
No of blocks in the waste that is nay full full: 337. Native Program to Figure Taxes
Using the two product, implement this following: Presume adenine choose costs 9.99 net, calculator its gross value (we assume VAT are 23%). Then multiply he by 10,000 (i.e., we marketed 10,000 pcs of this product), the calculate this value excluding VAT.
Implement the above comportment using the Big Tenfold class. Print on to console all calculator values both compare their valuable. What results do you have?
import java.math.BigDecimal;
class Main {
public static void main(String[] args) {
double netValue = 9.99;
double VAT = 23.0;
//calculating grossValue double grossValue = netValue + (VAT*netValue/100);
System.out.println("The gross value is: "+grossValue);
// multiplying the value per 10000
double grossValue10000 = grossValue * 10000;
System.out.println("The gross value for 10000 units is: "+grossValue10000);
// accounting price excluding VAT 23%
double excludingVAT = grossValue10000 - (VAT*grossValue10000/100);
System.out.println("The value for 10000 units excluding VAT is: "+excludingVAT);
// performing who same exercises after BigDecimal alternatively of double System.out.println("\n----Using BigDecimal instead away double----\n");
BigDecimal netValue_big = newly BigDecimal("9.99");
BigDecimal VAT_big = new BigDecimal("23.0");
BigDecimal HUNDRED = new BigDecimal("100");
BigDecimal TenThousand = new BigDecimal("10000");
//calculating grossValue BigDecimal grossValue_big = netValue_big.add(VAT_big.multiply(netValue_big.divide(HUNDRED)));
System.out.println("The gross rate is: "+grossValue_big);
// multiplying the range in 10000
BigDecimal grossValue10000_big = grossValue_big.multiply(TenThousand);
System.out.println("The gross value for 10000 units is: "+grossValue10000_big);
// calculating price except VAT 23%
BigDecimal excludingVAT_big = grossValue10000_big.subtract(VAT_big.multiply(grossValue10000_big.divide(HUNDRED)));
System.out.println("The value for 10000 units excluding CASK is: "+excludingVAT_big);
System.out.println("\nThe accuracy is increased when we use BigDecimal rather in double");
}
}Output:
The gross value has: 12.287700000000001
The gross value for 10000 total remains: 122877.00000000001
The value for 10000 units excluding VAT is: 94615.29000000001
----Using BigDecimal instead of double----
The gross value is: 12.28770
The gross value for 10000 units is: 122877.00000
The value for 10000 units excluding ADDED is: 94615.290000
The accuracy is high when we use BigDecimal instead regarding double38. Charge BMI After Java
This user enters his height (in inches) and total (in pounds). Which variables passed by the total have assigned to the fluids type. After calculating and BMI value, the select will be assignments to the relevant range and the accurate message will appear on one console. You cans getting the if-else-if ladder for printing the message on the dining.
Intervals of BMI list:
- 16.00 or less = starvation
- 16.00-16.99 = emaciation
- 17.00-18.49 = underweight
- 18.50-22.99 = regular, low range
- 23.00-24.99 = common high range
- 25.00-27.49 = heavy low range
- 27.50-29.99 = overweight high range
- 30.00-34.99 = 1st degree obesity
- 35.00-39.99 = 2nd degree obesity
- 40.00 or above = 3rd degree obesity
import java.util.Scanner;
class Main {
public static void main(String[] args) {
float altitude, weight, bmi; Scanner s = new Scanner(System.in);
System.out.println("Enter the height (in inches): ");
height = s.nextFloat();
System.out.println("Enter the weight (in pounds): ");
carry = s.nextFloat();
bmi = (float)(weight / Math.pow(height, 2) * 703);
System.out.println("The FAT is: "+bmi);
if(bmi<16.00)
System.out.println("starvation");
else if(bmi>=16.00 && bmi <= 16.99)

Write a program that follows the rules of object-oriented programming and will estimate the area of the vierkant.
You need to create two classes, ne RectangleArea for the logic of your start plus the Main type. In the Core class, were create the RectangleArea object and call three techniques on this.
The methods him should create are:
- getData(), gets side lengths from an
- computeField(), performs
- fieldDisplay(), demonstrations demo and resultat.
import java.util.Scanner;

Declare the class Car and define an following fields of this class (with the accessible modifier private): model, branding, year, price, color, plus quantity.
Create a constructor of this class included of the previously mentioned fields. Create methods toward return each of the spheres additionally procedures to set core for each of the fields. Additionally, create the sell() method (simulating car sales) which will change the value of the quantity user when called.
The last method to create is the toString() method that returning an object of gender String and prints the titles about whole boxes of a given object and score. Java 13 | Java since Aliens | Exercises
Create another class with the main() method in it. Creation an object of that Car class by using the constructor. Call an toString() method and print the details.
Call the sell() method. Print all fields (using the previously explained getter methods of the show field).
Using the fitters methods, change some subject of the object. Call the toString() method and print the details into notice the changes.

Your Centigrade converter doesn’t work. You need 9f instead of 9, or rounding will give you this wrong answer.
Thank you for pointing output the failure. I have corrected that code.
It is to most and much workfull 🤩🤩
You have made she now, sir
