Set LabelValue value and label in Java

Java 8Object Oriented ProgrammingProgramming

To set LabelValue value and label in Java, use the setLabel() and setValue() methods. Let us first see what we need to work with JavaTuples. To work with LabelValue class in JavaTuples, you need to import the following package −

import org.javatuples.LabelValue;

Note − Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuples −

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("\nUpdated = "+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]
