In the below example. we use the parseDouble() method of a Double class to parse Java String to double.

class Test {

  public static void main(String[] args) {
    double d1 = Double.parseDouble("121,4");
    double d2 = Double.parseDouble("21,3");
    double d3 = Double.parseDouble("2831,9");

    System.out.println(d1);
    System.out.println(d2);
    System.out.println(d3);
  }
}
Output: 121.4 21.3 2831.9
