Reverse A String In Java
Oct 7, 2014Here is my code:
public class ReverseString {
public static void main(String args[]) {
//quick wasy to reverse String in Java - Use StringBuffer
String str = "The rain in Spain falls mainly on the plain";
String revString = new StringBuffer(str).reverse().toString();
[Code] .....
The requirements: The program runs but for some reason it is not meeting the requirements. use the String method toCharArray and a loop to display the letters in the string in reverse order.
Using Split Method To Reverse A String
Oct 19, 2014In this exercise, create a program that asks a user for a phrase, then returns the phrase with the words in reverse order. Use the String class's .split() method for this.
Example input
The rain in Spain falls mainly on the plain
Example output
plain the on mainly falls Spain in rain The
While I understand the assignment, nowhere in the text is it covered how to reverse the order of the words in the string. I understand using the .split method, but not for this exercise.
Here is my code so far.
import java.util.*;
/**
* Java class SplitString
* This program asks for a phrase, and the code allows the phase to return in reverse order.
*/
public class SplitString {
public static void main (String[] args){
//set phrase input and mixed which will be the result
[Code] ....
As you can see, I have been googling this method and have come up nearly empty. My text does not cover the .reverse() method. The only thing it covers with .split() is how to split a string. I also tried StringBuilder with no success.
Store String Input In Array And Print In Reverse Order
Apr 5, 2014I have a college question ask me to write a class StringRevert which does the following:
-prompting user for an interger n
-creating an array of n string
-repeatedly read character string from user input and store them in the array until end of array is reached or user input -quit(quit should not saved in array)
-print the string from array in reverse order, from last enter to first enter.
-assume user always supplie correct input
This is what I've done so far but how to get it working.
import java.util.Scanner;
public class StringRevert {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("enter value of n: ");
int n1 = in.nextInt();
String[] n = new String[n1];

For Loops Reverse Method
Oct 29, 2014I'm trying to make a piece of code that writes a for Loop program using OOP. I need to create a class, name that class and have it contain several reverse methods and use a runner class to test it.So far this is the code I've come up with. Does it work or not?
public class loopDemo{
public static void main(string[]args){
String alphabet = "abcdefghijklmnopqrstuvwxyz";
public String reverse(){
char myBoi;
int myIta;
String tebahpla

How To Reverse Print Statement
Dec 2, 2014This code is supposed to convert a decimal base number to base 2, 8 or 16. It prints the number but it's supposed to be in the reverse order for example when converting 188 to base 16. it prints CB instead of BC.
package test;

public static void main(String[] args) {
Scanner input = new Scanner(System.in);

Java Reverse Order Using Pointers?
Oct 9, 2014This is what I have to do:Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.
Example:
"George Washington"
"Washington, George"
I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value.
import java.util.*;
import java.util.Scanner;
public class Test {
public static void main ( String [] args ) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter name: ");
String name = sc.nextLine();
String lastname = "";
String firstname = "";
for(int i = 0; i < name.length(); i++) {
if(name.charAt(i) == ' ')

Recursively Reverse Linked List?
Oct 17, 2014i tried everything but its giving me errors. i tried the for loop but its giving me something else.
this is what i have to do Write a recursive method that prints out the data elements of a linked list in reverse order.
Your method should take in as a parameter the head reference to a linked list. Then, write a recursive method that returns a count of the number of elements greater than a given threshold. You may assume that the data elements in the linked lists are ints. The parameters of your method are a reference to the linked list and a int value representing the threshold.
public class recursion3
{
public static void main(String [] args) {
char a [] = {'A', 'B','C','D','E'};
System.out.println(a);
}
public static String reverseString(String s) {

Java Linked List Reverse
Apr 12, 2014I am creating a recursive method to reverse a linked list in java. It works the first time when I call it, but I want it to work where I call it a second time and it reverses it to the original state. How can I get that to work with this implementation?
public void reverseList() {
System.out.printf("%-16s%-3s%n", "Name", "Score");
System.out.println("--------------- -----");
reverseList(first);
} public void reverseList(Node aNode) {
if (aNode != null) {
reverseList(aNode.next);
System.out.printf("%-15s%6s%n" , aNode.name , aNode.score);
}

Reverse Numbers Using Java Arrays
Feb 27, 2014I am trying to do this assignment but I can't get the needed output. Create a program that asks the user how many floating point numbers he wants to give. After this the program asks the numbers, stores them in an array and prints the contents of the array in reverse order.
Program is written to a class called ReverseNumbers.
Example output
How many floating point numbers do you want to type: 5
Type in 1. number: 5,4
Type in 2. number: 6
Type in 3. number: 7,2
Type in 4. number: -5
Type in 5. number: 2
Given numbers in reverse order:
2.0
-5.0
7.2
6.0
5.4
My code:
import java.util.Scanner;
public class apples {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
double[] numbers;
System.out.print("How many floating point numbers do you want to type: ");

Manipulate OriginalReversed So That It Contains Value Of Original In Reverse
Nov 17, 2014So In my program I have a String called original and I am supposed to prompt the user for a sentence and then Make a StringBuilder instance called “originalReversed” based off of original. Then I have to do is to "Manipulate originalReversed so that it contains the value of original in reverse. This is done with a single statement."
import java.util.Scanner;
public class StringBuilderPractice {
public static void main(String [] args)
{
Scanner input = new Scanner(System.in);
String original;
System.out.println("Please enter a sentence: ");
original = input.nextLine();
}
how to create the instance but not the second part where it says manipulate the value for the first part I think it might be
StringBuilder originalReversed = new StringBuilder(original);

Creating A Reverse List - Integer - Using Recursion
Jan 2, 2015I created this code, seems like it should be working properly and the code is right, but the output is not what it should be.The action gets a List<Integer> and should make it reversed.
As example: 1 2 3 4 5 ---> 5 4 3 2 1
The Nodes in the new list (lst2) should be in a reversed position.The code does compile with no errors.I do have Node<T> and List<T> classes
Java Code:
public class NodeReverse
{
public static void reverse (List<Integer> lst, Node<Integer> node, int counter, List<Integer> lst2, Node<Integer> pos) // Should make lst = lst2 while lst2 is the opposite to lst
{
node = node.getNext();
counter++;
if(node.getNext()!=null)
reverse(lst, node, counter, lst2, pos);

Reverse Number - Get Input And Result In Same Line
Feb 11, 2015I'm having trouble with a program, reversing numbers. I got the program itself to work! However, I am having an issue with the output.
import java.util.Scanner;
public class p1a {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
int n;
int reverse = 0;
[Code] .....
If I were to input, say 2341, I would get this: The reverse of 0 is 1432
The 0 should have been 2341, or whatever I input. What am I doing wrong?
I tried to move line 21 : (System.out.println("The reverse of " +n+ " is "+reverse);
Above the while loop, but instead get:
The reverse of 2341 is 0
How can I get my input and my result together in the same line?

Implement And Compare Reverse Methods From List
Oct 5, 2014What approach Collections.reverse() uses to reverse list? My task is to implement and compare reverse methods from list and i already did reveres with Recursion, Swap, Reading backward with creating reversed copy.
Does Collections.reverse() use different approach from those i already did?
