Hi team,

below is the code which i'm implementing after tfilelist using tjava to pick the files based on the conditions

Files in folder:

TEST_1415_1617.csv,

TEST_1515_1617.csv,

retry1_TEST_1515_1617.csv,

TEST_91011_1213.csv,

retry1_TEST_91011_1213.csv,

retry2_TEST_91011_1213.csv,

TEST_20011_1213.csv,

retry1_TEST_20011_1213.csv,

Pick only these

TEST_1415_1617.csv,

retry1_TEST_1515_1617.csv,

retry2_TEST_91011_1213.csv,

retry1_TEST_20011_1213.csv,

structure of job

tfilelist--->itertae--->tjava--->main--->trunjob

im getting an error with conversion of string to string[], but will tjava able to list all the files or it shows current files in each iteration, so will the below code work in my scenario

system.out.println((string.globalMap.get("tfleList_1_CURRENT_FILE"));

String[] fileNames = ((string.globalMap.get("tfleList_1_CURRENT_FILE"));

Map<String, Integer> map = new HashMap<>();

List<String> filesToProcess = new ArrayList<>();

for (int i = 0; i < fileNames.length; i++) {

if (fileNames[i].contains("retry")) {

Integer number = Integer.parseInt(fileNames[i].substring(5, 6));

if (map.get(fileNames[i].substring(7)) == null) {

map.put(fileNames[i].substring(7), number);

} else {

if (number > map.get(fileNames[i].substring(7))) {

map.put(fileNames[i].substring(7), number);

}

} else {

if (map.get(fileNames[i]) == null)

map.put(fileNames[i], 0);

}

for (Map.Entry<String, Integer> entry : map.entrySet()) {

if (entry.getValue() > 0) {

filesToProcess.add("retry" + entry.getValue() + "_" + entry.getKey());

} else {

filesToProcess.add(entry.getKey());

}

System.out.println(filesToProcess);

The error occurs on this line

String[] fileNames = ((string.globalMap.get("tfleList_1_CURRENT_FILE"));

Can't convert string to string[], to new a String array, should be:

String variableName[] = new String[capacity];

String variableName[] = {comma-delimited values};
