Steps − How to run JavaTuples program in Eclipse
The following is an example to set the LabelValue value in Java −
Example
import org.javatuples.LabelValue; public class Demo { public static void main(String[] args) { LabelValue<Integer, String> lv = new LabelValue<Integer, String>(5, "Rank"); System.out.println("LabelValue Tuple = "+lv); System.out.println("Get the key = "+lv.getLabel()); System.out.println("Get the value = "+lv.getValue()); // set new values LabelValue<Integer, String> lv2 = lv.setLabel(150); System.out.println("
Updated = "+lv2); LabelValue<Integer, String> lv3 = lv.setValue("Points"); System.out.println("Updated again = "+lv3); } }
Output
LabelValue Tuple = [5, Rank] Get the key = 5 Get the value = Rank Updated = [150, Rank] Updated again = [5, Points]
