How to Convert String Monetary Values to Doubles in Java?

Converting Strings to Doubles in Java

When working with numerical data stored as strings, converting them to double-precision floating-point numbers is often necessary. The Java programming language provides a convenient method to perform this conversion.

The Double.parseDouble() method allows you to convert a string representation of a double value into its numerical counterpart. Here's an example:

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

This code snippet takes the string "12.34" and converts it to a double value stored in the variable 'value'.

In your specific case, you mentioned wanting to convert strings representing monetary values from text fields. Here's how you can achieve that:

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

This code assumes that 'jlbTotal' and 'jlbPrice' are text field components that contain the string representations of the total amount and price, respectively. By using Double.parseDouble(), you're converting these strings into double values, allowing you to perform mathematical operations or further calculations as needed.
