Converting double to string

In Java, you can convert a double to a string using the Double.toString() method or the String.valueOf() method.

Here is an example using Double.toString():

double d = 123.45;
String s = Double.toString(d);

Here is an example using String.valueOf():

double d = 123.45;
String s = String.valueOf(d);

You can also use the DecimalFormat class to specify a particular format for the string representation of the double. Here is an example:

double d = 123.45;
DecimalFormat df = new DecimalFormat("#.##");
String s = df.format(d);

This will produce a string with exactly two decimal places, such as "123.45".
