Convert String to double in Java

Question

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

Answer 1

Use new BigDecimal(string). This will guarantee proper calculation later.

As a rule of thumb - always use BigDecimal for sensitive calculations like money.

Example:

String doubleAsString = "23.23";
BigDecimal price = new BigDecimal(doubleAsString);
BigDecimal total = price.plus(anotherPrice);
