Error in test case "959440.94f"

  • 0

    I tried to cast String to Double with code below. Java was able to cast "959440.94f" to double but expected answer for this test case is false. Why?

    public class Solution {
    public boolean isNumber(String s) {

        	 Double d=Double.valueOf(s);
        	 return true;
         }catch(Exception e){
        	 return false;
