Convert String to double in Java

Question

How can I convert a String such as \"12.34\" to a double in Java?

Answer 1

There is another way too.

Double temp = Double.valueOf(str);
number = temp.doubleValue();

Double is a class and "temp" is a variable. "number" is the final number you are looking for.

Answer 2

Try this, BigDecimal bdVal = new BigDecimal(str);

If you want Double only then try Double d = Double.valueOf(str); System.out.println(String.format("%.3f", new BigDecimal(d)));
