I have this error"String index out of range: 14
at java.lang.String.substring(Unknown Source)"
I am unable to find the mistake in my code. A little help would be great.

public class Algorithm23_1 {

	public static void main(String[] args) {
		String str="abacdaefkabfh";
		//String str="ababccccabbf";
		int length=1;
		//int end=str.length()-1;   
		int index=0;
		int index2=0;
		int length2=0;
		//System.out.println("Got here");		
		for(int i=0;i<str.length()-1;i++){
			if(str.charAt(i)<=str.charAt(i+1)){
			 	index=i;
			 	length++;
			}
			 	else {
			 		index2=index;
			 		length2=length;
			 		length=i;
			 		
			 		//transfer the index +length into new variables
			 		//reset original length to i
			 	// complexity is 0(n)
			}
			
			//System.out.println(length+index);
		}
		System.out.println(index2+" "+length2+" "+ str.substring(index2,index2+length2));
	}
}

Just trace through and figure out how str.substring(index2,index2+length2) would end up with a position beyond the length of 'str'.
