Java Data Type - 如何将String转换为Double

public class Main {

  public static void main(String[] args) {
    Double dObj1 = new Double("100.564");
    System.out.println(dObj1);

    Double dObj2 = Double.valueOf("10.6");

    System.out.println(dObj2);
    double d = Double.parseDouble("76.39");
    System.out.println(d);
  }
}
