creat a method in (java) that do the following: This will prompt the user for initial list of letters(a word).Then it will generate all permutations of these letters .Here it has to be mentioned that the permutations can also be of shorter length than the list of letters . For example, if the initial list of letters is "STOP", then "TOP" and "TOPS" are both valid permutations, but "STOPS" isn't

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

I need help with this code in Java

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){...

Needs to be written in java and completed using "for loops" or "nested for loops" and in one program just seperate methods: Write a program that calls these three methods. method 1 should print: 5 4 3 2 1 4 3 2 1 3 2 1 2 1 1 method 2 should print: 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 method 3 should create and array and store 10 multiples of 5 and print it out. Use for loop to generate the multiples and then print them out using a second for loop.

This question is in java The Sorts.java file is the sorting program we looked at . You can use either method listed in the example when coding. You want to add to the grades.java and calculations.java files so you put the list in numerical order. Write methods to find the median and the range. Have a toString method that prints the ordered list, the number of items in the list, the mean, median and range. Ex List: 20 , 30 , 40 , 75 , 93Number of elements: 5Mean: 51.60Median: 40Range: 73 Grades.java is the main file import java.util.Scanner;public class grades { public static void main(String[] args) { int n; calculation c = new calculation(); int array[] = new int[20]; System.out.print("Enter number of grades that are to be entered: "); Scanner scan = new Scanner(System.in); n = scan.nextInt(); System.out.println("Enter the grades: "); for(int i=0; i<n; i++) { array[i] = scan.nextInt(); if(array[i] < 0) {...

Write in JAVA

For java. Refer to picture.

Given a string, write a method that returns the number of occurrences of substrings "baba" or "mama" in the input string recursively. They may overlap. Do not use any loops within your code. Do not use any regular expressions and methods such as matches, split, replaceAll. "Maa mana, Test case 1: countBabaMama ("aba babaa amama ma") 2 Test case 2: countBabaMama ("bababamamama") 4
