Thread: Newbie, please help

I'm new to java, so please help. I'm trying to write this program that ignores unwanted characters in a string. For example,

if I ask for, and user types in : t!es@#t
it's going to ignore the "!@#", and prints just the "test"

I'm all out of ideas, please help. I'm using Eclipse IDE.

package chapterFour;
 
import java.util.Scanner;
 
public class tony {
 
	public static void main(String[] args) {
 
		Scanner scan = new Scanner(System.in);
 
		String word, ignore, newWord;
 
		System.out.print("Enter a word to clean up : ");
		word = scan.nextLine();
 
		ignore = "~!@#$%^&*()_+-";
 
		for(int a=0; a<word.length()-1; a++)
		{
			for(int b=0; b<ignore.length()-1; b++)
 
				if(word.charAt(a) != ignore.charAt(b))
				{
					newWord = word.substring(b);
 
				}
 
		}
 
		System.out.print(newWord);
 
	}
 
}

Thank you

Its' better, but not what I want . Now, if I type in "ignore" letters in sequence, I get the results I want. If I don't type them in sequence, I don't get what I want.

Example:

My ignore strings are "#&"

so if I type #&tony, I'll get tony (what I want),
but if I type &#tony, I get &#tony (not what I want).
if I type &tony, I get &tony
How can I make it so, it will ignore any strings in my ignore strings whether it's in sequence of if not.

package chapterFour;
 
import java.util.Scanner;
 
public class tony {
 
	public static void main(String[] args) {
 
		Scanner scan = new Scanner(System.in);
 
		String word, ignore, newWord;
 
		ignore = "#&";
 
		System.out.print("Enter a word to clean up : ");
		word = scan.nextLine();
 
		newWord = word.replace(ignore, "");
 
		System.out.println(newWord);
	}
}

You can simplify substantially your code by using regular expressions.

                String word = "&$t-o&$n(y)";
		String ignore = "[~!@#$%^&*()_+-]";
		word = word.replaceAll(ignore, "");
		System.out.println(word);

Note that in the ignore String the characters that you wish to remove from the word String are contained within [ and ]. The method replaceAll will search the entire word String looking for occurrences of the each character in the ignore String and replace it with an empty String.

Theres a good tutorial on regexp here.

Thank you it works
