Hi Sachin,

in this challenge you need to build a method "getTileCount" that accepts a char "tile" as an argument. Inside this method you need to use a for loop to go through every char of the mHand and compare it with your argument "tile", that you has passed inside the getTileCount method.

To analize every char in mHand you will need to make a char array of mHand through toCharArray() method. If char "tile" is == char the count will be increased by one. At the end you return an integer that gives you the number of chars that are equal to "tile".

So the code can look like this:

 public int getTileCount(char tile) {
    int count = 0;
// initial the count is 0
    for(char mHandChar: mHand.toCharArray()) {
//for every char mHandChar" in the array of chars from mHand
     if(mHandChar == tile) {
// your condition 
      count++; 
     }
    }
    return count;
  }

Please let me know if you need more help
