Chapter: String Handling Last Updated: 13-08-2016 13:24:02 UTC

Program:

            /* ............... START ............... */
                
public class JavaStringToDouble {

	public static void main(String args[]) {
		// Using parseDouble
		String string = "344.47";
		Double doubleVal = Double.parseDouble(string);
		System.out.println(doubleVal);

		Double doubleVal1 = new Double(string);
		System.out.println(doubleVal1);

		// Using valueOf method

		Double doubleVal2 = Double.valueOf(string);
		System.out.println(doubleVal2);
	}
}
                /* ............... END ............... */
        

Output

344.47
344.47
344.47

Notes:

  • The Double.parseDouble() static method parses the string argument and returns a double value. The parameters will be converted to a primitive double value.
  • Syntax : public static double parseDouble(String s) throws NumberFormatException.
  • The Double.valueOf() static method will return a Double object holding the value of the specified String.
  • Syntax : public static Double valueOf(String s) throws NumberFormatException.
