-deprication is used as option with
commands in java to describe the class, interface, constructor, method or field that has been changed in this version
for ex
javac is used as follows
javac [options] file name.java
at the place of option we can use -depreciation as follows
javac -deprecation filename.java
if we not use this option then copiler will tell the class in which deprecation has been arises and says to recompile with with -deprecation after recompiling the same it fully describe the class, interface, constructor, method or field that has been deprecated and then we should use newer version...
