Creating Array of Characters From a String

[ngc0202]

As the titled says, I am looking to try to make an array of the characters from a string. How should I go about doing this.

Look in the String API and you should find a method that does this for you.

You need to know the length of your String.
The size of your char[] is the same as your String's length.


Here's the code:

public class StringToArray {
	public static void main(String args[]){
		String text = "someText";
		
		int l = text.length();
		char[] v = new char[l];
		
		for (int i=0; i<l; i++){
			v[i] = text.charAt(i);
			System.out.println(v[i]);
		}
		
	}
}

Here's the code:

I disagree with this and go with my original recommendation. If you look in the String API, you'll find the toCharArray() method which creates the array in one fell swoop. So if we are going to be spoon-feeding answers here (much better to learn to look into the API in my opinion), I think a simpler and more straight-forward solution would be:

public class Fu1 {
  public static void main(String args[]) {
    String text = "someText";

    // isn't this much simpler?
    char[] myCharArray = text.toCharArray();

  }
}

Thanks. With a little editing, the code worked perfectly!

EDIT: I was talking to webbusiness23, I never saw your post Fubarable as I didn't refresh since arriving at webbusiness' post.

@ngc0202: Although the solution that webbusiness23 proposed is a good exercise, it would be better and more productive to use the String method as Fubarable suggested. Here's the link to the Javsa String APIs:

@webbusiness23: Although you were were trying to help the OP, it's not a good idea to post complete working code... too much temptation to cut, paste & forget. It is a much better to give pseudo code, links, snippets, etc. This way the OP develops code and learns.
