In Java: Write a program that removes all spaces from the given input. Ex: If the input is: Hello my name is John. the output is: HellomynameisJohn. Your program must define and call the following method. The method should return a string representing the input string without spaces. public static String removeSpaces (String userString)   import java.util.Scanner; public class LabProgram { /* Define your method here */ public static void main(String[] args) { /* Type your code here. */ } }

Examine this code and determine what happens when it is run: 1 public class Test { int x; 2 3 public Test(String t){ System.out.println("Test"); } public static void main(String[] args) { Test test = new Test ("boo"); System.out.println(test.x); } 4 5 6 7 8 10 } The program has a compile error because Test does not have a default constructor. The program has a compile error because System.out.println method cannot be invoked from the constructor. ) The program runs successfully and prints out: Test O The program has a compile error because you cannot create an object from the class that defines the object.

Do it here. On the next line. // return the double value here. return vectorStringValue; "1 ▸ Compilation Description A MathVector object will be passed to your method. Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. /** * Returns a String representation of this vector. The String should be in the format "[1, 2, 3]" * * @return a String representation of this vector * @apiNote **DO NOT** use the built-in (@code Arrays.toString()} method. */…

Computer Programming Java  Write a method named FirstHalf that receives a String parameter named word and then returns the first half of the string. You are guaranteed as a precondition that word has an even length greater than 1.

use the JCreator program for code in picture and show the output

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n)   public String repeatString(String str, int n) { //declare a string variable   //set up statements for repeating n number of times         //create the appropriate return statement   }

Print the two strings, firstString and secondString, in alphabetical order. Assume the strings are lowercase. End with newline. Sample output: capes rabbits 1 import java.util.Scanner; 2 3 public class OrderStrings { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); String firstString; String secondString; 4 6 7 8 firstString secondString scnr.next(); scnr.next(); 9. 10 11 12 /* Your solution goes here */ 13 14 } 15 }

Solve all the errors in the below method of C# language step by step and comment the error by correcting it. internal static void ReverseWordOrder(string str) { int i StringBuilder reverseSentence = new StringBuilder(); int Start = str.Length ; int End = str.Length - 1; while (Start > 0) { if (str[Start] == ' ') { i = Start  while (i <= ) { reverseSentence.Append(str[i]); i++; } reverseSentence.(' '); End = Start - 1; } Start-; } for (i = 0; i <= End; i++) { reverseSentence.Append(str[i]); } Console.WriteLine(reverseSentence.ToString());
