Implement a method String[] dedup(String[] a) that returns the objects in
a[] in sorted order, with duplicates removed.
Step by step
Solved in 4 steps with 2 images
- A string containing text and possibly delimiters has been split into tokens and stored in String[] tokens. Each token is either an open delimiter, a close delimiter, or a substring that is not a delimiter. You will write the method getDelimitersList, which returns an ArrayList containing all the open and close delimiters found in tokens in their original order. Eg) (,),<q> , </q> import java.util.*; public class Delimiters { /** The open and close delimiters **/ private String openDel; private String closeDel; /** Constructs a Delimiters object were open is the open delimiter and close is the * close delimiter. * Precondition: open and close are non-empty strings */ public Delimiters (String open, String close) { openDel = open; closeDel = close; } /** Returns an ArrayList of delimiters from the array tokens, as described in part (a). */ public ArrayList<String> getDelimitersList(String[] tokens) { /* to be implemented in part a */ } public…java using set or map Write a method called firstUnique() that takes a string as a parameter and finds the first non-repeating character in it by doing only one traversal of it. For example, ‘w’ is the first non-repeating character in the string “hellohowareyou”.The split method in the String class returns an array of strings consisting of the substrings split by the delimiters. However, the delimiters are not returned. Implement the following new method that returns an array of strings consisting of the substrings split by the matching delimiters, including the matching delimiters. public static String[] split(String s, String regex) For example, split("ab#12#453", "#") returns ab, #, 12, #, and 453 in an array of String and split("a?b?gf#e", "[?#]") returns a, ?, b, ?, gf, #, and e in an array of String.
- Using JAVA, write a method that modifies an ArrayList<String>, moving all strings starting with an uppercase letter to the front, without otherwise changing the order of the elements. Write a test program to demonstrate the correct operation of the method.Write a program in Java programming language that reads an array of strings! Program should write the shortest string from the array.Solution in Java Implement a method removeWord() that takes two string parameters: sentence - the sentence you are to remove a word from. word - the word you are to remove from the sentence. Your method should take a string, sentence and remove word from it. It will return a new string without word in the sentence. Examples removeWord("One two three four", "two") → "One three four" ● removeWord("Bob has a kid", "kid") → "Bob has a" (Ctrl)
- using java, please solve it and send it as java code and send it with output screenshot Write the following method that splits a string into substrings using delimiter characters. public static ArrayList<String> split(String s, String delimiters); For example, split("AB#C D?EF#45", "# ?") returns a vector containing AB, C, D, EF, and 45. Write a test program that prompts the user to enter a string and delimiters and displays the substrings separated by a space. (You are not allowed to use the regex for splitting a string in this exercise.)LeetCode Given an array of strings words representing an English Dictionary, return the longest word in words that can be built one character at a time by other words in words. If there is more than one possible answer, return the longest word with the smallest lexicographical order. If there is no answer, return the empty string. Example 1: Input: words = ["w","wo","wor","worl","wo Output: "world" Explanation: The word "world" can be buil Example 2: Input: words = ["a", "banana", "app","appl" Output: "apple" Explanation: Both "apply" and "apple" can Constraints: • 1 <= words.length <= 1000 • 1 <= words [i]. length <= 30 words [1] consists of lowercase English letters.Write a program in Java that reads an array of strings. Program should output the shortest string from the array.
- Write a program in Java programming language that reads an array of strings!The program should write all the strings from array that have at least one letter 'a'.Write a method that returns an array list of Characterfrom a string using the following header:public static ArrayList<Character> toCharacterArray(String s)For example, toCharacterArray("abc") returns an array list that containscharacters 'a', 'b', and 'c'.import java.util.ArrayList;import java.util.Arrays; public class PS07A{/*** Write the method named mesh.* * Start with two ArrayLists of String, A and B, each with * its elements in alphabetical order and without any duplicates. * Return a new list containing the first N elements from the two * lists. The result list should be in alphabetical order and without * duplicates. A and B will both have a size which is N or more. * Your solution should make a single pass over A and B, taking * advantage of the fact that they are in alphabetical order, * copying elements directly to the new list.* * Remember, to see if one String is "greater than" or "less than" * another, you need to use the compareTo() method, not the < or > * operators. * * Examples:* mesh(["a","c","z"], ["b","f","z"], 3) returns ["a","b","c"]* mesh(["a","c","z"], ["c","f","z"], 3) returns ["a","c","f"]* mesh(["f","g","z"], ["c","f","g"], 3) returns ["c","f","g"]* * @param a an ArrayList of String in alphabetical…
