Managing Tags Using SDK (AWS SDK for Java)

The following Java code example does the following:

  • Create an object with tags.

  • Retrieve tag set.

  • Update the tag set (replace the existing tag set).

For instructions on how to create and test a working sample, see Testing the Java Code Examples.
