String x= "25"; int y=Double.parseDouble(x); double r=Math.sqrt(y); System.out.println(r);Give the output of the following code:
String P = "20", Q ="19"; int a = Integer.parseInt(P); int b = Integer.valueOf(Q); System.out.println(a+""+b);The method to convert a String to double is:
- String.toDouble()
- Double.Parsedouble()
- Double.parseDouble(String)
