Remove line breaks in java(new lines text is converted into one line)

Ex String:

Actual text :
Abc
def
Efg

If we want to conver the above words into one line " Abc def Efg"

Code :

String filterSummaryText=desktop.<JTextArea>find(Objects.BioMarkerFilters.FilterSummaryText).getText();

String text = filterSummaryText.replace("\n", "").replace("\r", "");
return text;
