string printing converted to numbers while using ".charAt(1)+.chatAt(2)"

[noobplus]

Hi,
I'm back I was to exams, My project is over.. thanks to the moderators..
My coding is

public class stringing {

	public static void main(String[] args)
	{
		String a=new String("bcaefdhigklj"); 
		for(int i=0;i<a.length();i=i+3)
		{
			//System.out.println(a.charAt(i+1)+"\n");//here it works fine
			System.out.println(a.charAt(i+1)+a.charAt(i+2)+a.charAt(i)+"\n");
                             //but here it prints numbers
		}
	}
}

output:

294
303
312
321

When you concatenate chars using the (+) operator the value will be converted into the ASCII code that represent the char. For instance a = 97; b = 98; c = 99, etc. To make it concatenate as a string you need to convert the chars into string. The simplest way is to concatenate a string with it, you can write it like:

System.out.println("" + a.charAt(i + 1) + a.charAt( i + 2) + a.charAt(i));
