I realy cant get why this does not work.. been trying for two hours to get it working... its supposed to check if any char is repeated in the string.. It works if I type inn 'abc def' , but eg 'abc def gh' does not work..
import java.util.Scanner;

class repchar
{
	public static void main(String args[])
	{
		Scanner input = new Scanner(System.in);
		
		System.out.println("Pleas enter a string.");
		String str = input.nextLine();
		int sLength = str.length();
		boolean match = false;
		int i = 0;
		while(!match && i < sLength)
		{
			char chkChar = str.charAt(i);
			int j = i + 1;
			while(!match && j < sLength)
			{
				if(str.charAt(j) == chkChar)
					match = true;
				j++;
			}
			i++;
		}
		System.out.println(match);
	}
}
