Write a method called isAbecedarian that takes a String and returns a boolean indicating whether the word is abecedarian. Your method can be iterative or recursive

Write a Java method that takes a variable of type String and returns a boolean value. The method returns true if the taken string contains a valid password, false otherwise. A valid password should satisfy all the following conditions: • It can contain any character • It contains at least 6 but not more than 20 characters • The number of letters (both uppercase and lowercase) is equal to the number of digits The method's header is as follows. public static boolean password (String s) Sample run Result String s = "Hello12345"; password(s); String s = "hellohil234567"; password(s); "hi21"; password(s); true boolean b = true boolean b = String s = boolean b = false Paragraph B.

basic java please Write a method starTheString that accepts a string of any size/length and a number. It should then return a new string that is two copies of the string with a set of stars between them equal to the number. For example, the call of starTheString("Hello", 5) o would return "*****Hello*****" 5 stars - Hello - 5 Stars starTheString ("Goodbye", 3) o would return "***Goodbye***" 3 stars – Goodbye - 3 Stars

Write a java class method named addQuotes that takes one parameter of type String. The method should return a string that's indentical to it's argument, but with a double quote character added at the beginning and end of the string.

Write 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 ×ばつ 2 + ?2 ×ばつ 22 +⋯+ ?7 ×ばつ 215where b0, b1, ?2, ... ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 +たす 0×ばつかける2 +たす 1×ばつかける22 +たす 1×ばつかける23 =わ 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. The word or sentence should only contain letters (no digits,...

Write a Java application that calculates the sum of a series of integers that are passedto method sum() using a variable-length argument list. Test your method with severalcalls, each of which with different number of arguments

Given a long string use recursion to traverse the string and replace every vowel (A,E,I,O,U) with an @ sign. You cannot change the method header. public String encodeVowels(String s){ // Your code here }

java Write a public static method named getStringReversed that takes in 1 argument of type String and returns the String in reverse order.

Write a static recursive method in Java called mRecursion that displays all of the permutations of the charactersin a string passed to the method as its argument. For example, the character sequence abc has thefollowing permutations: acb, bac, bca, cab, cba. Then Write a static method called getInput that get aninput string from the user and passed it to the mRecursion method written above in a method call.Please does so using what I already had //Get input from in to call recursive method //to display those char permutations public static String getInput ( ) { Scanner in = new Scanner(System.in); String combination = in.nextLine(); System.out.println("Enter string:); return stringComb; //Method to show permutations of a desired string// This only return 3 string combination for some reason static void myRecursion(String aString) { //isEmpty check if ( aString.length() == 0){...

I need help creating a code below - Write a recursive method called digitCount() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10. Ex: If the input is: 345 the method digitCount() returns and the program outputs: 3

Exercise 1Write a Java method random that generates and returns a random number between 14 and 59(using SecureRandom). Test your method several times using a main function
