Your compiler also told you exactly the line number and method or class that is
deprecated. Check the API documentation for that class or method and read what
the alternatives are. Deprecated methods and classes are not guaranteed to exist
in later versions of Java so you shouldn't use them although they might work in
your current Java version.

kind regards,

Jos

Add your classpath on the environmental variables.

Compile using javac on the command line so that you may be able to see the output on the command prompt.

javac -Xlint classname.java

You will be able to see the details .
