Find char index where contains() found sequence

Question

    if(input.contains("Angle ")) {
        input.charAt(?);
    }

So, basically, how would you find the char directly after "Angle "? In absolute simplest terms, how do you find the indexes in which "Angle " was found?

Answer 1

You can use the indexOf method both to find out that the input contains the string, and where its index is:

int pos = input.indexOf("Angle ");
if (pos >= 0) {
    ... // Substring is found at index pos
}
