Iterate Through Label-Value Tuple in Java

To iterate through the LabelValue tuple value, use a simple for loop just like what we do in other collections. 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 iterate through LabelValue Tuple 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());
      System.out.println("\nIterating through the values of the LabelValue class = ");
      for (Object ele : lv)
         System.out.println(ele);
   }
}

Output

LabelValue Tuple = [5, Rank]
Get the key = 5
Get the value = Rank
Iterating through the values of the LabelValue class =
5
Rank
