isPrime Method
A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false se otherwise. Demonstrate the method in a complete
TIP: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.

Prime Numbers A prime number is a number that can be evenly divided by only itself and 1. For example, the number 5 is prime because it can be evenly divided by only 1 and 5. The number 6, however, is not prime because it can be evenly divided by 1, 2, 3, and 6. Write a Boolean method named IsPrime that takes an integer as an argument and returns true if the argument is a prime number or false otherwise. Use the method in an application that lets the user enter a number and then displays a message indicating whether the number is prime.
QUESTION 2
A prime number is a number that is evenly divisible only by itself and 1. For example, the
number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however,
is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a method named isPrime, which takes an integer as an argument and returns true if
the argument is a prime number, or false otherwise. Demonstrate the method in a complete
program.
Tip: Recall that the % operator divides one number by another, and returns the remainder

- 6.17 LAB: Max magnitude Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the method returns: 7 Ex: If the inputs are: -8 -2 the method returns: -8 Note: The method does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute-value built-in math method. Your program must define and call a method:public static int maxMagnitude(int userVal1, int userVal2) tested with 5,7 -8,-2, 25,-50 import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner input = new…arrow_forwardMethod: sumOdds(value: int): This method will sum all the odd values from 1 upto the value passed by parameter.

Test your method with several calls, each with a different number of arguments. Exercise 6.17 JHTP: (Dice Rolling) Write an application to simulate the rolling of two dice. The application should use an object of class Random once to roll the first die and again to roll the second die. The sum of the two values should then be calculated. Each die can show an integer value from 1 to 6, so the sum of the clause will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent. Figure 6.21 shows the 36 possible combinations of the two die. Your application should roll the dice 36,000 times. Use a one-dimensional array to tally the number of times each possible sum appears. Display the results in a tabular format. Fig. 6.21 | The possible sums of two dice.arrow_forward
- Add another public method called add() to TestFraction1 class. This method adds another fraction to the ‘calling object’. Thus, the method will take a Fraction class object as a parameter, add this parameter fraction to the calling object (fraction), and return a Fraction object as a result. HINT: we can use cross multiplication to determine the numerator of the resultant Fraction. The denominator of the resultant Fraction is simply the multiplication of the denominators of the two other Fractions. import java.util.Scanner;//test programpublic class TestFraction1{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is…arrow_forwardRepeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n) public String repeatString(String str, int n) { //declare a string variable //set up statements for repeating n number of times //create the appropriate return statement }arrow_forwardvoid Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class.

Write the results to the terminal and also to the output file called, "output.txt" and remind the user to look at that file if he/she wants to.

Task To accomplish the above, do the following: • Write the two methods outlined below. • Test your program and screenshot your successful test. carMaintenance method This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.). It should display the services and their prices as follows: Services: Oil Change, Tune up, Brake Job, Transmission Service, respectively: 59.99, 111.99, 189.99, 149.99 These should be stored in parallel arrays.
