How to increment a number in a String in Java?-CodePudding

I want to increment a number in a string in Java 8. Like this:

String lifes = "3";
lifes--

But i know that way is impossible, does you know other way to do it?

CodePudding user response：

Integer.parseInt("3")   1

The above statement results 4 which means we are parsing the String value as Integer and then incrementing in here, hope it helps!

CodePudding user response：

If the string only contains the number, I'd do something like this -

lifes = String.valueOf(Integer.parseInt(lifes) - 1);
