Suppress deprecated import warning in Java

问题:

In Java, if you import a deprecated class:

import SomeDeprecatedClass;

You get this warning: The type SomeDeprecatedClass is deprecated

Is there a way to suppress this warning?

回答1:

Use this annotation on your class or method:

@SuppressWarnings( "deprecation" )

回答2:

To avoid the warning: do not import the class

instead use the fully qualified class name

and use it in as few locations as possible.

回答3:

As a hack you can not do the import and use the fully qualified name inside the code.

You might also try javac -Xlint:-deprecation not sure if that would address it.

回答4:

I solved this by changing the import to:

import package.*

then annotating the method that used the deprecated classes with@SuppressWarnings("deprecation")

回答5:

Suppose that you are overriding/implementing an interface with a deprecated method (such as the getUnicodeStream(String columnLabel) in java.sql.ResultSet) then you will not get rid of deprecation warnings just by using the annotation @SuppressWarnings( "deprecation" ), unless you also annotate the same new method with the @Deprecated annotation. This is logical, because otherwise you could "undeprecate" a method by just overriding its interface description.

回答6:

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");.
