Return index if if it exists within the target in an array

Question

I have the following array in which I need to return the index if it exists within the array. I think that I am on the right track however I am confused on how I should return my target index to actually produce what I am trying to return. If the index doesn't exist it should return -1 and if multiple targets are found the first occurrence should be returned. The code that I have currently written is below.

public int getIndex(String target) {
    for (int i = 0; i < arr.length;i++) { 
        for (int j = 0; j < arr[i].length; j++) { 
            if (arr[i][j] == target) { 
               return target;
            }
        }
    }
    return -1;
}

Any help or tips would be appreciated.
