New to Java

Hi all,

I wonder if someone can help me and point out where I'm going wrong.


I want to count the number of substring starting with 'd' and ending with 'e' in a string supplied by a user.

currently my code is only counting the number of 'd' and 'e' characters in the string.

{

    public static void main (String [] args) 
    
    {
    	Scanner input = new Scanner (System.in);
    	
    	
    	String mstring;// string variable that the user will enter
    	
    	int i = 0; // upstep variable
    	
    	int count = 0; // int variable to count the number of substrings
    	
    	System.out.print("Enter a string: ");
    	
    	
    	mstring = input.nextLine();
    	
    	
    	while (i != mstring.length())
    		
    		{
    			    			
    			if(mstring.charAt(i)=='d'){count++;}
    			
    			else if (mstring.charAt(i)=='e'){count++;}
    				
    			
    			i++;
    		}
    	
    	System.out.println("The total d e substrings is " + count);
    	
    }
    
    
}

For example if the user enters adbedeaadffe the total number of substrings should be 5 but I'm getting 6 as the program is just counting the number of times it comes across 'd' and 'e'

Can anyone shed some light on this for me thanks.
