Java: Misspell reporter using regex (how to parse for misspells)

I am creating a program that parses strings to report instances of misspells. I want it to report multiple instances opposed to one single variable. I had it interpret user input for instance;

GOOGGOUGGUIG

and take that string and report all instances where "GO" was spelled incorrectly 4 times because as seen in the above user entry we have "OG", "UG", "GU" and "IG".

So my result should be

Y was spelled incorrectly x/count times.

I don't care about the pattern reversal portion. I only used it to find instances for when I used the single variable.

import java.util.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class misspellReporter
{
  public static void main(String[] args)
  {
      Scanner keyboard = new Scanner(System.in);
      String singleString = "";
      System.out.println("Enter text here");
      singleString = keyboard.nextLine();

          String str = singleString;
          //String strToSearch = "OG"; //I used this at first
          String[] strToSearch = {"GU", "UG", "IG", "GI"}; //I want to use this array instead
          String strToSearchReversed = new StringBuffer(strToSearch).reverse().toString();
          Pattern strPattern = Pattern.compile(strToSearchReversed);
          Matcher matcher = strPattern.matcher(str);
          int counter = 0;
          while(matcher.find()) {
              ++counter;
          }

      System.out.println(strToSearch+" was spelt as "+strToSearchReversed+" "+counter+" times");
  }
}

Thank you ahead of time! The reason this question is different for me is because I haven't seen anyone else on the forum parse with matcher and patterns. I've used other methods but this one has a specific action to it that I take an interest in.
