How do I make a variable global across a Java file

In lua I could just do global variablename and bam its global is there a simple way to do this in java?

Here is my code, I want the loc variable to be global so the public View getView(int position, View convertView, ViewGroup parent){ can use it:

class custom_row_adapter extends ArrayAdapter<Integer> {
      custom_row_adapter(Context context, int picId, String url) {
        super(context, R.layout.activity_custom_row_adapter, picId);
        String loc = url;
}
@Override
public View getView(int position, View convertView, ViewGroup parent){
        LayoutInflater picInflater = LayoutInflater.from(getContext());
        View customView = picInflater.inflate(R.layout.activity_custom_row_adapter, parent, false);
        String singlePic = getItem(loc + String.valueOf(position) + ".jpg"); **//this is where loc is viewed**
        ImageView theImage = (ImageView) customView.findViewById(R.id.singleImg);
        Glide.with(this).load(singlePic).into(theImage);
        return customView;
}

}

        super(context, R.layout.activity_custom_row_adapter, picId);
