Complete the isExact Reverse() method in Reverse.java as follows: The method takes two Strings x and y as parameters and returns a boolean. The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. - Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true false

How do I add, If s is null, the method should return null. If s is the blank string, "", the method should return the blank string to my code? import java.util.Scanner;public class replaceFirst { public static String replaceFirst(String Str,char c) { Str = Str.substring(0,0) + c + Str.substring(0 + 1);// modified string return Str; } public static void main(String[] args) { System.out.print( replaceFirst("basant",'c')); } }

How do I create a code that has a public static method named replaceFirst that takes in a String s and a char c as arguments. The method will return a modified String replacing the first character with the one that was passed in. (Do not print out the String) Java

Need help with this java problem. Some Websites impose certain rules for passwords.Write a method that checks whether a string is a valid password. The method must takes a password as a parameter and return a boolean value. If the password is valid, returns true, otherwise, return false. Suppose the password rules are as follows:- A password must have at least eight characters.- A password must contain only letters and digits.- A password must contain at least two digits. Please make sure you write a comment line to document what your method does. Write a program that prompts the user to enter a password, then call the method that checks the password, and displays "Valid Password" if the rulesare followed, or Invalid Password otherwise. The main program must allow the user to check multiple passwords. It should ask the user "Do you want to continue checking anther password (y/n)?"

1. Using java-Write a method that checks if two strings are palindromes. Two strings are palindromes ifthey contain the same characters but in strict reverse order. For example, "abcd" and"dcba" are palindromes. For the purposes of this method, if either input string is null, themethod should return false. If both input strings are empty, the method should return true.The signature of the method should be as follows.public static boolean arePalindromes(String s1, Strings2)

Please don;t change anything. put your code line 5. Java Write a static method named toCelsius that takes a single parameter fahrenheit as a double, converts Fahrenheit to Celsius, and returns the value as a double. The formula is 5 / 9 * (F - 32) = C

Write a method with the following header to format the integerwith the specified width.public static String format(int number, int width)The method returns a string for the number with one or more prefix 0s. The size of thestring is the width. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns thestring representation for the number. For example, format(34, 1) returns 34.Write a test program that prompts the user to enter a number and its width, anddisplays a string returned by invoking format(number, width).

Program to compute interest = p * r * t, where p = 10ドルK, rate = 6%, t = 10 years; these values are to be passed from main() Besides main() the program has two methods: one that computes the interest and on that rounds interest to two decimal places public class DisplayInterest public static void main(String[] args) call a method that will do the computation with values for the above variables; with the exception of year, they are double main() displays computed interest after rounding computation method() rounding method() Note:- Please type and execute this java program and also need an output for this java program.
