        /*
         * Each of the Number subclasses that wrap primitive
         * numeric types also provides a parseXXXX() method
         * (for example, parseFloat()) that can be used to
         * convert strings to primitive numbers. Since a
         * primitive type is returned instead of an object,
         * the parseFloat() method is more direct than the
         * valueOf() method.

        int intVar = Integer.parseInt("100");
        System.out.println("intVar    = " + intVar);

        double doubleVar = Double.parseDouble("20.289");
        System.out.println("doubleVar = " + doubleVar);
    }
}
Output
intVar    = 100
doubleVar = 20.289
