What error are you getting? Works fine for me. import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner in = new Scanner(System.in); Double num1 = in.nextDouble(); Double num2 = in.nextDouble(); double sum; sum=num1 + num2; System.out.println(sum); } } :::INPUT::: 1 2.3 :::OUTPUT: 3.3 :::INPUT::: 1.5 3 :::OUTPUT::: 4.5 :::INPUT::: 1 2 ::::OUTPUT::: 3.0

If your locale uses a comma (,) instead of a period (.) for decimals, then you can change that setting in your JRE so that it reflects your locale instead. That's how the compiler will know which one to expect.

If your system eg Windows has set different separator, because local country habits, installed java expect this sarator instead standard English dot this shows expected decimal separator //import java.text.DecimalFormatSymbols; char dSepar = new DecimalFormatSymbols() .getDecimalSeparator(); System.out.println( dSepar );
