(Number of days in a year) Write a method that returns the number of days in a year using the following header:
public static int numberOfDaysInAYear(int year)Write a test program that displays the number of days in year from 2000 to 2020.
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 prime
(language: Intellij-Java)
Part One: Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5).
Part2: Write a method which gets a value from the user and convert that value from Celsius to Fahrenheit:
- For Celsius to Fahrenheit conversion use: F = 9*C/5 + 32
- Print the result of the conversion
Part3: Create a method which takes an integer array input from the user and reverses the elements in the array. Print the reversed array.
- For example, the expected “reversed” result for an array [5,33,0,8,2] is [2,8,0,33,5]
- Don't use any inbuilt/existing array reverse method. Try to write the reversing logic

- Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram". Note: The header of the method is as follows: public static boolean isAnagram(String s1, String s2) Sample Input #1: Enter two strings: Silent listen Sample Output #1: The string “Silent” and “listen” are anagrams.

The player throws two dice and may cover the number representing the total or the two numbers on the dice. For example, for a throw of 3 and 5, the player may cover the 3 and the 5 or just the 8. Play continues until all the numbers are covered. The goal is to cover all numbers in the fewest rolls. Create a Clacker application that displays 12 buttons numbered 1 through 12. Each of these buttons can be clicked to ‘cover’ it. A covered button displays nothing. Another button labelled Roll can be clicked to roll the dice. Include labels to display the appropriate die images for each roll. Another label displays the number of rolls taken. A New Game button can be clicked to clear the labels and uncover the buttons for a new game.arrow_forward
