You cannot update one line or one item in the file,<br />
you need to read the whole file and re-write it to a new<br />
plcae and while doing it you can parse the contents get to the element you need and replace it.

Just a word of caution - I'm sure you know but just in case: when running and especially debugging this sort of programs<br />
in real life certainly make sure that you have copies of all your files - there's nothing easier to do thhan to lose<br />
your the whole file with one wrong operator.

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Programming Languages-Other

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
