  • This program makes use of valueOf() method of Double class for the transformation of string values into double.
  • Similar to the previous program, a String type object str1 is  declared with value of 8762.0
  • Then this object is passed to valueOf() method as argument..
  • The converted value is stored into double type variable namely, num1.
  • Afterwards, num1 containing 8762.0 is printed.
