如何将字符串解析为int？

Question

my string is 743.4445 and I want it to show 743 so it has to parse to double and then parse to int so I try like this

(int)(Double.valueOf(743.4445);

(actually 743.4445 is from server thus I don't know exactly value)

what am I suppose to do?

Answer 1

why not google "java get whole number"

double d = Double.valueOf(s.trim()).doubleValue();

Heck, for that matter why not use IndexOf on the string looking for the.? :)

Answer 2

Please try this.

Store this value in one string and try this.

String number = "743.4445";

(int)Double.parseDouble(number)

Answer 3

Why not use NumberFormat.setParseIntegerOnly(boolean value) method?

Example:

String s = "743.5555";
NumberFormat format = NumberFormat.getInstance();
format.setParseIntegerOnly (true);
int value = format.parse(s).intValue();
