Iterate through LabelValue 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 −
Steps − How to run JavaTuples program in Eclipse
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("
Iterating 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
