다음 코드는 for loop
을 사용하여 JSONArray
의 요소를 반복합니다.Java 8에서 JSONArray를 반복하는 방법
import org.apache.log4j.Logger;
import org.json.JSONArray;
import org.json.JSONObject;
import java.util.stream.IntStream;
public class Pmt {
private String[] patchInformation_svnRevisionpublic;
private final Logger logger = Logger.getLogger(Pmt.class.getName());
private static final String COMMITS_IN_PATCH_IDENTIFIER = "patchInformation_svnRevisionpublic"; //key used to identify the commits in a patch from JSON response received from PMT
private static final String KEY_STRING = "name";
private static final String VALUE_STRING = "value";
public String[] getPublicGitCommitHashes(JSONArray jsonArray) {
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = (JSONObject) jsonArray.get(i);
String tempName = (String) jsonObject.get(KEY_STRING);
if (tempName.equals(COMMITS_IN_PATCH_IDENTIFIER)) {
JSONArray tempCommitsJSONArray = (JSONArray) jsonObject.get(VALUE_STRING);
//initializing the patchInformation_svnRevisionpublic array
patchInformation_svnRevisionpublic = new String[tempCommitsJSONArray.length()];
// for ommiting the white spaces at the begingin and end of the commits
IntStream.range(0, tempCommitsJSONArray.length()).forEach(j -> patchInformation_svnRevisionpublic[j] = ((String) tempCommitsJSONArray.get(j)).trim());
logger.info(" The commits hashes obtained from WSO2 PMT are successfully saved to an array");
System.out.println("The commit Ids are");
// for printing all the commits ID associated with a patch
IntStream.range(0, patchInformation_svnRevisionpublic.length).mapToObj(i1 -> patchInformation_svnRevisionpublic[i1]).forEach(System.out::println);
System.out.println();
break;
}
}
//to prevent from internaal representation by returning referecnce to mutable object
String clonedPatchInformation_svnRevisionpublic[] = patchInformation_svnRevisionpublic.clone();
return clonedPatchInformation_svnRevisionpublic;
}
}
어떻게 같은 작업을 수행 할 streams API
또는 forEach
같은 Java 8
의 새로운 기능을 사용합니까. 미리 감사드립니다.
