I am not very comfortable with Strings in Java. The problem I am facing is, taking a string that contains a sentence and reversing the words. Example would be, "Hi I am Bob" and changing it to "Bob am I Hi". Then returning the String.
My initial thoughts were to change the string into a character array and then manually doing the work with loops and tedious comparison statements. I quickly realized that there must be a better way but I am not very familiar with strings in Java to know what a more sufficient way would be.

Basically the requirements are to take a sentence (string of text) and check to see how many times specific words come up and then add to the counter depending on the word.
But I can not seem to get it to add the instances of the goodwords and badwords.
package Strings;
import java.io.*;
public class SentimentAnalyser {
private static String analyse(String text) {
int pw = 0;
int nw = 0;
String[] searchword = { "bad", "terrible", "good", "awesome" };
[Code] ....

This is the code that i have used to delete particular String from text file. It works absolutely fine on eclipse and netbeans.. But on deployment(in tomcat) it fails to delete message/rename or delete original file even though all permissions for modifying the files in the folder has been given to all users.
This is my code:
package com.pro.model;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

I am trying below challenge to display first three characters three times if the size of the string is greater than 3.
Say if i send hello i should get helhelhel
if i send xyz i should get xyzxyzxyz
I wrote as below
public String front3(String str) {
if(str.length()==3){
return str+str+str;
}
if(str.length()>3){
String str2=new String(new char[]{str.charAt(0),str.charAt(1),str.charAt(2)});
return str2;
}
}
I am getting error as below
Error:public String front3(String str) {
^^^^^^^^^^^^^^^^^^
This method must return a result of type String
Possible problem: the if-statement structure may theoretically allow a run to reach the end of the method without calling return. Consider adding a last line in the method return some_value; so a value is always returned.

The program is to accept a string and display all the palindrome words(the words that are same even if they are reversed-------->mom,madam,malayalam etc.)in the string.
I need to solve this program urgently.
There are no syntax errors but after typing in the sentence,no output is displayed. This is my program....
import java.util.*;
class palindrome_test
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
System.out.println("Enter a sentence");
String usersInput=in.nextLine();

I have created an enumerated data type that represents months. In my program I have asked the user for the month. I hold the month entered by user into a string variable. From that string variable I'm trying to display the month using my enumerated data type. I know I can use if statements, but is there another simple way to do it?
import java.util.Scanner;
public class demo {
//Enum class called month that has constants in it representing months
enum month{january,february,march,april,may,june, july,august,september,
october,november, december};

Write a program using a while-loop (and a for-loop) that asks the user to enter a string, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the string. (So, you will have two separate program codes, one using a while-loop and the other one using a for-loop.)
Example:
Enter a string: "Hello, JAVA is my favorite programming language."
Enter a character: e
The number of times the specified character appears in the string: 3
I don't even know where to begin I've only got this
import java.util.Scanner;
public class letterCounter {
public static void main(String [] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a string");
String myString = sc.nextLine();
System.out.println("Enter a letter");
String letter = sc.nextLine();
}
}

I need making the toString() method return a String rather than display a message to the screen. Also, I'm not supposed to call the toString method in my demo class to test it, so what should I do instead?
public class cupDispenser {
String location;
int noOfCups;
cupDispenser(String location,int cups)
{
this.location=location;
this.noOfCups=cups;
}
public String getlocation()

how to split and then represent the splitted sentence.Suppose I have:
Java Code:
String sentence = "I Love my mother <=> I Love my father";
String[] array = sentence.split("->"); mh_sh_highlight_all('java');
But how can I get now the lefthandside String values which is "I love my mother" and righthandside "I love my father"? I tried smth like:
Java Code:
String[] leftHandSide = array[0].split(" ");
String[] rightHandSide = array[1].split(" "); mh_sh_highlight_all('java');
But it's not working - getting error.

public class Setning
{
public static void main(String[] setning) {
skrivHeleSetningen(setning);
}
private static void skrivHeleSetningen(String[] setning) {
[Code] .....
What this do is:
First write out the whole sentence (WORKS)
Write out number of words (WORK)
Then I would like it to write out number of characters (DOESN'T WORK)
The arguments are given in "run configurations" using eclipse

So I have to design a program that takes a word and reverses the order of it. The exact directions are:Write a recursive method void reverse() that reverses a sentence. For example:
[code = Java]
Sentence greeting = new Sentence("Hello!");
greeting.reverse();
System.out.println(greeting.getText());
[/code]
prints the string "!olleH".
Implement a recursive solution by removing the first character, reversing a sentence consisting of the remaining text, and combining the two. So basically my biggest issue is my method to actually reverse the word.
public class Sentance
{
private String Word;
public Sentance (String aWord)
{
Word = aWord;

i am new to programming skills it may be silly question for experience but for me it's new thing. actually i tried a lot but i am facing problem when i trying to take input through Scanner. if i will take input a sentence directly as a string it's working . but when i am trying with Scanner the first word is showing next are not showing
public class Demo2
{
public static void main(String[] args)
{
String s1="hi how are you";
s1=s1.replace('a', 'A');
s1 =s1.replace('e', 'E');
s1 =s1.replace('i', 'I');
[Code]...
this is working properly.
but when i trying with Scanner i am facing problem.
public class Demo2
{
public static void main(String[] args)
{
java.util.Scanner scn= new java.util.Scanner(System.in)
String s1=scn.next();
s1=s1.replace('a', 'A');

Ok, so I have to make a program that tells the user to type a sentence and at the end of the sentence a "." must be put to end the program. If a "." period is not entered, it must re-prompt the user to enter a period. On top of all this, the program has to count the number of letters in the sentence. I cant seem to get the while loop working and I cant find anywhere how to make a counter count the number of letters.

The purpose of this program is to translate a user inputed sentence into morseCode. It seems like everything is right to me, but I'm simply not getting output! What am I doing wrong, or what should I add/change?
Here is the main class:

public static String myUserInput;
public static char[] myAlph = {'A','B','C','D','E','F','G','H','I','J','K','L','M',

I've been given an assignment for my Programming Fundamentals class that requires the user to enter a word/sentence to encrypt or decipher, as well as requiring the user to enter a key in which to encrpyt/decrypt the input by.
So a = no shift, b = a shift by 1 and so on.
But I'm completely lost as to what to do, and after searching for Vigenere Cipher topics, they look completely different to mine and (hardly) include prompts?This is my code:
/**
