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.
Sample Input #1:
Enter two strings:
teach
peach
Sample Output #1:
The string “teach” and “peach” aren’t anagrams.
Method overloading: given the following methods, write down the printed output of the method calls.
Do not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics:
It contains at least eight characters.
It contains at most 12 characters.
It contains only alphabetic characters, digits and the underscore (‘_’) character.
It does not start with a digit.
It has a mix of upper-case and lower-case characters.
Your class must contain the following method: public static String checkPassword(String input)
This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.

One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues.

- Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…arrow_forwardTRUE OR FALSE.
