Is it possible to convert strings in java to double directly?

Answer 1

Not directly. A String is an object, and a double is a primitive data type. To do the conversion you must first convert the String to a Double object (note the capital D in double), then convert that object to a double data type (lowercase d in double). Double is an object, double is a primitive data type. Here's a class that will convert a String to a double:

public class StringToDouble{

public static void main (String[] arguments) {

String s = "100.00";

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

System.out.println("double d = " + d);

}

}
