convert string with decimal to integer

Question

I am given a string (100.0). I need to convert that to int. How do I do that?

When I do Integer.parseInt(). I am getting below error.

java.lang.NumberFormatException: For input string: "100.0"

Answer 1

You can achieve this by using java.lang.Double class

 

Double valueToDouble = Double.parseDouble("100.0");

int valueint = valueToDouble .intValue();
