以下是使用AWS SDK for Java中DeleteStackResponse的代码示例：

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.cloudformation.AmazonCloudFormation;
import com.amazonaws.services.cloudformation.AmazonCloudFormationClientBuilder;
import com.amazonaws.services.cloudformation.model.DeleteStackRequest;
import com.amazonaws.services.cloudformation.model.DeleteStackResult;
import com.amazonaws.services.cloudformation.model.StackStatus;

public class DeleteStackExample {
    public static void main(String[] args) {
        // 设置您的AWS访问密钥
        String accessKey = "YOUR_ACCESS_KEY";
        String secretKey = "YOUR_SECRET_KEY";

        // 创建AWS凭证
        BasicAWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);

        // 创建CloudFormation客户端
        AmazonCloudFormation cloudFormationClient = AmazonCloudFormationClientBuilder.standard()
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withRegion("us-west-2") // 设置您的AWS区域
                .build();

        // 创建DeleteStack请求
        DeleteStackRequest deleteStackRequest = new DeleteStackRequest()
                .withStackName("YOUR_STACK_NAME"); // 设置要删除的堆栈名称

        // 发送DeleteStack请求并获取响应
        DeleteStackResult deleteStackResult = cloudFormationClient.deleteStack(deleteStackRequest);

        // 检查堆栈状态
        String stackStatus = deleteStackResult.getStack().getStackStatus();
        System.out.println("Stack Status: " + stackStatus);

        // 等待堆栈删除完成
        while (!stackStatus.equals(StackStatus.DELETE_COMPLETE.toString())) {
            // 获取堆栈状态
            stackStatus = cloudFormationClient.describeStacks(deleteStackRequest).getStacks().get(0).getStackStatus();
            System.out.println("Stack Status: " + stackStatus);

            try {
                // 等待5秒
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        System.out.println("Stack deletion completed.");
    }
}

请确保替换accessKey、secretKey和YOUR_STACK_NAME与您的实际值，并根据需要设置AWS区域。这个示例演示如何使用AWS SDK for Java删除一个CloudFormation堆栈，并等待堆栈删除完成。
