Need help, trying to print strings backwards while ignoring certain things.

Question

To clarify the topic what I mean is I want to spell the words the user inputs backwards while skipping over certain characters. Here's my code:
import javax.swing.*;
import java.util.*;
import java.text.*;
import java.io.*;
class SConvert{
private static final char BLANK = ' ';
private static final String stop = "STOP";
public static void main(String[] args){
char[] ignore = new char[21];
ignore[0] = '.';
ignore[1] = '/';
ignore[2] = '>';
ignore[3] = '<';
ignore[4] = ',';
ignore[5] = '?';
ignore[6] = '-';
ignore[7] = '~';
ignore[8] = '!';
ignore[9] = '@';
ignore[10] = '#';
ignore[11] = '$';
ignore[12] = '*';
ignore[13] = '&';
ignore[14] = '^';
ignore[15] = '%';
ignore[16] = '`';
ignore[17] = '_';
ignore[18] = '+';
ignore[19] = '=';
ignore[20] = '|';
String word, statement, append;
boolean go = true;
int i, numOfchar, index;
char[] chr;
index = 0;
word = " ";
statement = " ";
append = " ";
Scanner scanner = new Scanner(System.in);
while (go){
System.out.println("Enter a word");
word = scanner.next();
chr = word.toCharArray();
numOfchar = word.length();
if (word.equals(stop)){
     break;
else if (index < numOfchar && word.charAt(index) == BLANK + BLANK){
     index = BLANK;
else if (index < numOfchar && word.charAt(index) == (int)ignore[19]){ //Trying to range for entire array, I don't know how.
     index++;
else
       for (i = word.length() - 1; i >= 0; i--)
          statement = statement + chr;
          append = append + " " + statement;
System.out.print(append + " ");
What's messing me up is the fact that whenever I try to enter words into the program, printing append only repeat EVERY occurance of statement. For example, say I type in "Ham with gravy." I get "maH htiwmaH yvarghtiwmaH".
That's not what I want. Also, I don't know how to make the entire array of ignore available to the program, anyway to do that?                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

Answer 1

Wow. What's with the hostility? Even I was in error of detecting anything that could have solve the problem completely there's no need to use such a negative tone, epsecaility with someone who is learning to program in OOP, let alone the syntax of Java. Also, no your program did not solve all of my problems in it's original form. Let's take a look at it.
Here's your code:
import java.lang.String;
import java.util.*;
public class ReverseString {
  public void ReverseString(){
  public void printReverse(String s){
     int i;
    String noPrint = "no print'";
    char ch = '*';
    if(s.length()>1) printReverse(s.substring(1));
     ch = s.charAt(0);
    if (!noPrint.contains(ch + " ")) System.out.print(ch);
    return;
  public static void main(String[] args) {
      String myString = Here is my String.;
   System.out.print("My String: " + myString + " Reverse: ");
   new ReverseString().printReverse(add);
   System.out.println();
}In it's original state the program doesn't allow for any user input, which is something I needed (and added on my own), it doesn't convert the ignore[] I had in my original code to anything readable (however this can be done in the noprint String quite easy as someone else mentioned earlier.) the if command does in fact ignore the special characters in noprint String HOWEVER it doesn' t not print those characters as they would appear in the myString String in the position that it original appeared in (which is the primary problem I am having.) That is the problem with your code and why it is not the complete to soultion to my homework problem. I've modified your code to satisifed all but one of the problems.
Modified:
import java.lang.String;
import java.util.*;
public class ReverseString {
  public void ReverseString(){
  public void printReverse(String s){
     int i;
    String noPrint = "~`!@#$%^&()-=+[{]}\':;?/>.<,'";
    char ch = '*';
    if(s.length()>1) printReverse(s.substring(1));
     ch = s.charAt(0);
    if (!noPrint.contains(ch + " ")) System.out.print(ch);
    return;
  public static void main(String[] args) {
       Scanner scanner = new Scanner(System.in);
      String myString;
      String add = " ";
       while (true) {
   System.out.println("Please input String.");
   myString = scanner.next();
   add = add + myString;
          if (myString.equals("STOP")){
               break;
   System.out.print("My String: " + add + " Reverse: ");
   new ReverseString().printReverse(add);
   System.out.println();
}If you run this code you'll see what am talking about. The only remaining problem, which I am about to restate if you are still unclear of it, is that the noprint String contents are ignored but not printed in the original position. If you are still having trouble understanding what I am talking about then let me show what I got by running the program.
String: Ham with grav?y
Reverse: yvarg htiw maH. [Note the ? is missing.]
By removing the ! in the if command I get:
Reverse: y?varg htiw maH. [Now the ? is in the wrong position.]
It's suppose to be:
String: Ham with grav?y
Reverse: yvarg htiw ma?H.
Secondly, I understand that you are frustrated with my apparent lack of understanding of proper Java tems and syntax but you must keep in mind I am student thus I am not fully aware of java as you are. With that one would expect you to act with a bit more patience, yet you not only took offense to an innocent comment you choose to slander my name and intelligence by erasing your code and calling my understanding of Java, ?ignorant.? I may be less than careful with my choice of words concerning Java but I do understand enough code to know the inner workings of a typical program, so please refrain from calling me ignorant or any variant of this in the future.
I merely asked for help from general populous, do not think I owe you any particular praise for your code even if I find it is not exactly what I desired. I may be new to java but I am not new the message boards. With that said I find your response awfully rude and ask if you to refrain from do so in the future. I'm assuming you are an adult so act least act like someone with a bit of civility. If you were so committed to believing your code was the de facto solution to this problem then you could have simply asked why I say what I said, if had done so and shown me the error of my statement I would have not taken offense. Instead you choose to throw a fit and deleted your code. I do not know if you are like this around other board members but you should at least show courtesy to all members of this forum regardless of their time here.
With that said, I think I've all ready found a solution to this problem I've had. I'll just tell the program to simply count over the position the character is in. That way it will stay in the same position.
