       public class JavaStringToDoubleExample
   {
     public static void main(String[] args)
     {
       //We can convert String to Double using one of the following ways.
       //1. Construct Double using constructor.
       Double dObj1 = new Double("100.564");
       System.out.println(dObj1);
      
       //2. Use valueOf method of Double class. This method is static.
       String str1 = "100.476";
       Double dObj2 = Double.valueOf(str1);
       System.out.println(dObj2);
      
       /*
       To convert a String object to a double primitive value parseDouble method
       of Double class. This is a static method.
       */
      
       String str2 = "76.39";
       double d = Double.parseDouble(str2);
       System.out.println(d);
      
       //Please note that these methods can throw a NumberFormatException if
       //string can not be parsed.
      
     }
   }
