Need Help With Assignment

[zeo]

I'm taking an introductory to java course. I have been completing assignments that are rather basic with if else statements, etc.

I need some help on where I'm supposed to start off here.

Here's the assignment

Write a Java program Search.java to prompt the user to enter an arbitrary string of characters. The program searches for digit characters, and extracts the characters that are digits, and also extracts the characters that are non digits, and provides a count of each.

Is this on a window or can you use java.util.Scanner ?

[Junky]

When starting an assingment take baby steps.

Write a class and a main method that does nothing.
Make sure it compiles (fix errors).
Move on.
Get user input and print back to screen.
Make sure it compiles and runs.
Iterate over the user input and print one character at a time.
Make sure it compiles and runs.
Iterate over the user input and only print the numbers.
etc

Junky is correct. What have you done so far? Follow Junky's steps and let us know which one you got stuck on, what you have so far, and what errors you get.

import javax.swing.*;

class Search
{
public static void main (String [] args)
{
String str;

str = JOptionPane.showInputDialog("Enter String");

int result = str.length();

JOptionPane.showMessageDialog(null,
"String" +result);
}

}

So Far I just need to figure out a way to seperate the characters entered into digits and non digits.

Example of How it is supposed to look like
User enters: hjjkk144

The message box is supposed to display the following:
3 Digits: 144
5 Characters: hjjkk

Did you move onto the next step I suggested and loop over the String and print each character one at a time?

Thats what I'm in the process of doing atm, and I'm completely lost =\

Nah, use a regex Pattern of "(\d*)(\s*)" and get the returned Matcher's forst and second matches (the digits and the chars, respectively).

Op is struggling with loops and if statements. Do you really think they can handle regex at this point.

Also, if this work will be marked I bet the teacher will know if they use regex it isn't their code and fail them.
