When it comes to encrypting and decrypting sensitive data in a Java application while leveraging the security of AWS, the AWS Key Management Service (KMS) provides a robust solution. AWS KMS enables you to create and control the encryption keys used to encrypt your data securely. Here's a step-by-step example of how to use AWS KMS to encrypt and decrypt data in a Java application:

Step 1: Set Up AWS SDK for Java
Ensure that you have the AWS SDK for Java set up in your project. You can include the necessary dependencies in your pom.xml if you're using Maven, or add the SDK JAR files to your classpath manually.

Step 2: Initialize AWS Client
Initialize the AWS client using your AWS credentials and specify the AWS region.
