How to fetch all the values of one column using column name in dynamoDB table in java?

Question

I have a dynamoDB table in my aws account. I can create client like this.

AmazonDynamoDB amazonDynamoDB =
            AmazonDynamoDBClient.builder().withRegion("eu-west-1").withCredentials(creds).build();
    DynamoDB dynamoDB = new DynamoDB(amazonDynamoDB);
    Table table = dynamoDB.getTable("table name");

Suppose there is column name "content". I want to get a list or set of all values in "content" column.
