Is it OK to use deprecated methods Java?
A deprecated class or method is like that. It is no longer important. It is so unimportant, in fact, that you should no longer use it, since it has been superseded and may cease to exist in the future.
How can you tell if a method is deprecated?
To make the compiler warn you of the details of which methods you used that were deprecated use the javac.exe -deprecation switch. Then look in the Javadoc for the deprecated methods to find out the recommended replacements. Sometimes you just have to rename. Sometimes the replacements work quite differently.
Why are deprecated methods kept in the API?
From the definition of deprecated: A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists. The method is kept in the API for backward compatibility for an unspecified period of time, and may in future releases be removed.
When to not use a deprecation warning method?
As a general rule, when something has been deprecated, you should not use it in any new code and, when maintaining code, strive to eliminate the deprecation warnings. As we shall see in Section 2.2, there is already at least one example of a deprecation warning method that has altogether stopped working.
