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.
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
(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.
// L1
// L2
// L3
// L4
// L5
Complete the dry run table (you may not need all rows):
x != 16 ?
// L6
even (x) ?

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.
