Question

I am new to java dev. I want to add numbers in an editText.
i.e if user types in 15 in editText, it should add the numbers 1 + 5 giving the result 6.
Is there a function for it in java. In C# it is ToCharArray() but I don’t know what it’s called in java.
Thanks

Answer 1

you can use

    String str = "15";
    char[] cArray = str.toCharArray();

    int sum = 0;
    for (char c : cArray)
        sum += Character.digit(c, 10);
