How Can I Convert Strings to Doubles in Java?

Converting Strings to Doubles in Java

Java provides a straightforward method to convert Strings representing numerical values into their double equivalents: Double.parseDouble(). This method accepts a String argument and returns a double precision floating-point number.

For example, consider the following Java code:

String text = "12.34"; // a String containing a numerical value
double value = Double.parseDouble(text);

In this example, the String text is converted to the double value value. This value can now be used in arithmetic operations or stored as a double variable.

This conversion is particularly useful when dealing with user input or data retrieval, as it allows the programmer to easily convert String representations of numbers into numerical data types for further processing.
