In Java, if you import a deprecated class:
import SomeDeprecatedClass;
You get this warning: The type SomeDeprecatedClass is deprecat
you can use:
javac FileName.java -Xlint:-deprecation
But then this will give you warnings and also tell you the part of the code that is causing deprecation or using deprecated API. Now either you can run your code with these warnings or make appropriate changes in the code.
In my case I was using someListItem.addItem("red color") whereas the compiler wanted me to use someListItem.add("red color");.
