Write a java method that takes four integers as arguments (int a, int b, int c, int d), that prints Match if and only if at least three values match otherwise, it prints No Match.
QUESTION: Creating a JAVA program which should implement a method that verifies whether a given 4 x 4 square (containing 16 values) is a Magic Square with a given magicValue. Also, adding code to generate values for a Magic Square based on a magicValue.
The code here is good to solve for verifying if it is a magic square but not n generating a new Magic Square, it is not as in the picture. The sum in row and columns are not equal.
PLEASE, PLEASE, PLEASE, don't post code from anywhere else. Please help me by working on this code here.

import java.awt.*;
public class MagicSquare{
static int checkMag(int mat[][],int M)
{
// Function for checking Magic square
int i, j,n=4; int sum=0; // filling matrix with its count value // starting from 1;
for ( i = 0; i < n; i++) {
for ( j = 0; j < n; j++)
sum=sum+mat[i][j];
if(sum!=M)

Write (only) a Java static method that is your own implementation of the pow() method. The function receives two parameters – the first parameter is the value to be raised by the exponent, and the second is the exponent to raise the value to, the function returns xy. assume that the value being raised is a double and the exponent is a non-negative integer. You cannot use any built-in Java functions or methods.

- Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane. Write a program that reads a string from the keyboard and test whether the string contain any one of these words. Your program should find words like cAt that differ only in case. Have your program reject only lines that contain one or more of the three words exactly. For example, concatenation is a small category should not be considered profane. This problem can be solved easily. If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…arrow_forwardHow to write a recursive method called palindrome and a non-recursive method called palindromenonrecursive in java that determine if a string is a palidrome (ignore characters that are not letters). Then write a driver to test the two versions of the two methods. (A palindrome is a string that reads the same forward as well as backward. For example, “otto” and “never odd or even” are palindromes)arrow_forwardWrite a recursive Java method that takes a String as a parameter and returns true if the String is a palindrome. You may assume that the string only contains lower case characters (i.e. no numbers, spaces, punctuation, etc).arrow_forward
- Write a Java program Primes that finds all possible prime numbers in the range of (1, n], where 1 < n ≤ 1000. Solve the problem by implementing and using the helper method isPrime(number) which determines whether the given argument is prime or not. (the code should have the structure as in the picture)arrow_forwardWRITE A JAVA PROGRAM Methods can be used to define reusable code and organize and simplify code. Problem:- Suppose that you need to find the sum of integers from 5 to 15, from 16 to 30, and from 31 to 39, respectively. Define a public static sum method that take two int parameters -> (int start, int end) In the method, use for loop to add all the number from start to end. Later, invoke the sum inside the main method. Do the sum for each a) 5 to 15; b) 16 to 30; and c) 31 to 39 separately and later print the results. Output: Sum from 5 to 15 is 110 Sum from 16 to 30 is 345 Sum from 31 to 39 is 315arrow_forwardWrite a recursive method called drawTriangle() that outputs lines of '*' to form an upside down isosceles triangle. Method drawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the last line for correct formatting. Hint: The number of '*' decreases by 2 for every line drawn. Ex: If the input of the program is: 3 the method drawTriangle() outputs: *** * Ex: If the input of the program is: 19 the method drawTriangle() outputs: ******************* ***************** *************** ************* *********** ********* ******* ***** *** * Note: No space is output before the first '*' on the first line when the base length is 19.arrow_forward
- Write a recursive Java method that calculates the sum of n positive integer numbers. The math function is: f(n) = 1 + 2 + 3 + … + n. Jack, Peter and John were exploring a tunnel which allows only one person to pass through. Jack entered the tunnel first, followed by Peter. John entered the tunnel the last. The tunnel has a dead end. So the team has to turn back and retrieve from the tunnel one by one. Write a Java program based on a suitable data structure to simulate this process.arrow_forwardYou have a card on which the letter J is written on one side and K on the other. You want to seeall of the possible ways the card will land if you drop it n times. Write a recursive method thatprints each session of dropping the cards with J's and K's. For example if you drop it 4 times in agiven session, all possible ways to drop it are as follows (in exactly the specified order): (java code)arrow_forwardWrite a recursive method in java that returns a string that contains the octal representation of a positive integer. Test your method. Hint: An octal number is the base-8 number system, and uses the digits 0 to 7. For example, the number 12 can be converted to octal number as follows: Divide by 8, the remainder represents the first digit so 12/8 = 1 and the remainder is 4 so the first digit is 4. The quotient is 1. Then we divide 1 over 8 we get zero and the remainder is 1. The second digit is 1 and we stop. The equivalent octal number for 12 is 14.arrow_forward

Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline.arrow_forwardWrite the following programs in Java: In the Converter class write the static method, bin2decimal(String bin). The parameter for this method is an unsigned (nonnegative) binary number represented by a string. The method returns the decimal equivalent for the binary parameter, as an integer.If the binary string is invalid (contains characters other than ‘0’ and ‘1’), the method returns -1. Convert from a binary (b) string with up to 16 digits to decimal (d) using the following formula:? = ?0 + ?1 × 2 + ?2 × 22 +⋯+ ?7 × 215where b0, b1, ?2, … ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 + 0×2 + 1×22 + 1×23 = 13 in decimal. Side note: You may NOT use the decode method of the Long wrapper class instead of this formula. In the Converter class write another static method, english2encrypted(String english). The parameter for this method is a word or sentence represented by a string.
