Question

I am trying to convert a string to a double but get a NumberFormatException.

Here is my code:

String x = "";
// String ary[]=new String[10];
while (finalstr.charAt(stpr) != ' ') {
    // System.out.print(finalstr.charAt(stpr));
    Character c = new Character(finalstr.charAt(stpr));

    String s = c.toString(c);
    ary[i] = s;
    x = x + ary[i];
    i++;

    stpr++;
    // first++;
}
// System.out.print(x);
String yo = x;
// System.out.print(yo); //it prints well
// double d = Double.valueOf(yo.trim()).doubleValue();
double doubleprim = Double.parseDouble(yo);
System.out.print(doubleprim);

All help appreciated.

Answer 1

try Double.valueOf(yo.trim()).doubleValue();
