Question

I’m looking for a way to convert the first letter of a string to a lower case letter. The code I’m using pulls a random String from an array, displays the string in a text view, and then uses it to display an image. All of the strings in the array have their first letter capitalized but image files stored in the app cannot have capital letters, of course.

String source = "drawable/"
//monb is randomly selected from an array, not hardcoded as it is here
String monb = "Picture";

//I need code here that will take monb and convert it from "Picture" to "picture"

String uri = source + monb;
    int imageResource = getResources().getIdentifier(uri, null, getPackageName());
    ImageView imageView = (ImageView) findViewById(R.id.monpic);
    Drawable image = getResources().getDrawable(imageResource);
    imageView.setImageDrawable(image);

Thanks!

    if (monb.length() <= 1) {
        monb = monb.toLowerCase();
    } else {
        monb = monb.substring(0, 1).toLowerCase() + monb.substring(1);
    }
