1. Write a method called arrayTimesFive
The method takes one array of doubles as a parameter
It multiplies each element in the array by 5 and stores the result
It returns nothing
True or False:
(a) In a debugger, we can choose whether to step into, step over, or step out of a particular method call.
(b) Debuggers, tests, and println() statements are all legitimate ways to help us find errors in our code.
(iii) int x = 10;
while (x != 16) {
}
LINE
System.out.print (x +
if (even (x)) {
X = = x / 2;
} else {
X
}
X = 3 x + 1;
*
");
System.out.println(x);
// L7
Assume the method even returns true if the argument is an even number, and
false otherwise.

Write a method that checks whether a string is a valid password. Suppose the password rules are as follows: A password must have at least eight characters.

Write a program that prompts the user to enter a password and displays Valid Password if the rules are followed or Invalid Password otherwise.arrow_forward
- 2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not. Sample Run 1: Enter Two positive integers X and Y: 12 13 12 and 13 are relatively prime Sample Run 2: Enter Two positive integers X and Y: 12 14 12 and 14 are not relatively primearrow_forward(In Java language) Create a class Called NetflixDemo Create two objects “user1” and “user2” of the Netflix class pictured below) Set various class variables for the Netflix class using these two objects.

Then, draw a triangle using these 3 points. Allow the user to specify a number of random points to be generated inside of the triangle. For each random point that is within the boundaries of the triangle draw a small dot at each of the points that are halfway between the randomly generated point and each vertex of the triangle. Do not draw the randomly generated point. Allow the user to repeat the process without removing the old dots. Allow the user to clear the screen.arrow_forward
- Examine the following method header; then write an example call to the method. private void ResetValue(ref int value)arrow_forwardJAVA Notes: all program codes should be written with method/s separated from the main() structure. Use a separate code files for each. Programming Problems: 1. Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, otherwise return false. Also write a program to test your method. 2. Write a program that prompts the user to enter a sequence of characters and output the number of vowels and consonants separately. (use the method isVowel written in problem 1). 3. Write a program that output inflation rates for two successive years and whether the inflation rates are increasing or decreasing. Ask the user to input the current price of an item and its price, one year and two years ago. To calculate the inflation rate for a year, subtract the price of the item for that year and from the price of the item from one year ago and then divide the result by the price a year ago. Your program must contain a method to calculate the results. Use…arrow_forwardc) Write a public static method getFirstD() with the following: o The method accepts 2 arguments: the first argument is an array of int, and the second is a value of int. The method returns a value of int type. o The method finds and returns the last element in the array which is divisible by the second argument, e.g. 8 is divisible by 4, but 9 is not divisible by 4. I The method returns your student ID number, if no divisible number is found in the array. Use a while loop to access the array elements. *NO more than 6 statement lines are allowed in the method body. YRIGHarrow_forward

Name your program IceCream.java For this program, you will need to write 3 methods, as follows: dispayTotal Takes a double parameter for the total food price. Takes another double parameter for the percent tip calls the calculateTax method to add taxes to the price. calls the calculateTip method to add the tip to the price. Displays the price to two decimal places along with the message "With taxes and tip, your total comes to $<price>" returns nothing Note that you will need to watch the 16 videos before you can complete this method calculateTax Takes in a double parameter for the subtotal for the food.
