Question

String x = "39.33";
String result ;
Double x1 = new Double(x);
System.err.println("value :"+ x1);
String[] parts = x1.toString().split("\\.");

if(parts != null )
{
 if((Integer.parseInt(parts[1])) > 0)
{
       result =x1;

}
 else
{
result= parts[0];
}
 }

please let me know the best way to format/split the value:
my need is….

 if x is 39
 so x1 is 39.0
 so i need result =39

 if x is 39.33
 so x1 is 39.33
 so i need result =39.33

i dont want to use split or condition checking if((Integer.parseInt(parts[1])) > 0).. please let me know the best way for this?

Answer 1

Try this:

Double d = Double.parseDouble("35.0");
String result = NumberFormat.getNumberInstance().format(d.doubleValue())
System.out.println(result);
