Convert String to double in Java

Question

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

Answer 1

You can use Double.parseDouble() to convert a String to a double:

String text = "12.34"; // example String double value = Double.parseDouble(text); 

For your case it looks like you want:

double total = Double.parseDouble(jlbTotal.getText()); double price = Double.parseDouble(jlbPrice.getText());
