Write a method to replace all spaces in a string with '%20'. You may assume that the string has sufficient space at the end to hold the additional characters, and that you are given the "true" length of the string. (Note: If implementing in Java, please use a character array so that you can perform this operation in place.) EXAMPLE Input: "Mr John Smith ", 13 Output: "Mr%20John%20Smith"

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

can you plz write it in java.util.scanner form

Please write a java code using the photo below. The second photo is the output of my program that I am writing

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false

You are given an array of n integers. Write a java method that splitsthe numbers of the array into two equal groups so that the GCD of all numbers in the second group is equal to one and the GCD of all numbers in the first group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. You are not allowed to define new arrays. 3. 4. You are not allowed to definenew methods or use methods from java libraries. Sample run of the method: Inputarray: (6,7,9,4,3,2} Output Group two: (7,9,3} Group one: (2,4,6} I Ignore Order of numbers. Order is not important //Ignore Order of numbers. Order is not important

Can you help me fix my code in Java, please? I am stuck to keep going. Thank you

Write in JAVA

For java. Refer to picture.

java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".
