Have used the split n to add the text to the new line but is not adding can i get a solution

Question

public static void inputvalue(WebDriver driver,Map<String, String> formEntryMap,String colKey)

{

if(formEntryMap.containsKey(colKey))

{

String [] input= formEntryMap.get(colKey).trim().split("\n");

for(String inputItem:input)

{

String xPath = xpath of the input field

inputEntry(driver, xPath,inputItem);

}

}

}

There are 2 values in the feature file : 121414  52323434 but these values are getting added in the text box without adding the values in the new line i.e first value should be 121414 and second value should come below the first value.

Can i get a solution pls
