How to get the names of all accessible Datasets?

[Electricks94]

Hello,
I got a small problem. Basically, I just want to receive the names of all the datasets which I can access. My code looks like BigQuery API described how to do it:

import java.util.Iterator;
import java.util.List;

import com.google.api.gax.paging.Page;
//import com.google.appengine.repackaged.org.apache.lucene.analysis.compound.hyphenation.TernaryTree.Iterator;
import com.google.cloud.bigquery.*;
import com.google.cloud.bigquery.BigQuery.DatasetListOption;

public class GetBQInfo {
	public static void getinfo (){
	BigQuery bigquery = BigQueryOptions.getDefaultInstance()
		    .toBuilder()
		    .setProjectId("testprojekt-175408")
		    .build()
		    .getService();
	 String projectId = "testprojekt-175408";
	 Page<Dataset> datasets = bigquery.listDatasets(projectId, DatasetListOption.pageSize(100));
	 Iterator<Dataset> datasetIterator = datasets.iterateAll();
	 while (datasetIterator.hasNext()) {
	   Dataset dataset = datasetIterator.next();
	   // do something with the dataset
	 }
	 }
}

But I cannot compile the code because I get this message from eclipse:
Type mismatch: cannot convert from Iterable<Dataset> to Iterator<Dataset>
I tried a lot of things but nothing worked for me yet. Does anyone know how I can solve this?

Iterator and Iterable are two different Java interfaces, so they cannot be used interchangeably. In particular, you cannot assign the return value of iterateAll (an Iterable) to your variable, which is an Iterator. Try changing the line:
Iterator<Dataset> datasetIterator = datasets.iterateAll();
to:
Iterable<Dataset> datasetIterator = datasets.iterateAll();

Thank you for your answer. It works fine now!

Great! I'll close this out.
