Get a value from Unit Tuple class in Java

Use the getValueX() method to get a value from Unit Tuple class in Java at a particular index. For example, getValue0().

Let us first see what we need to work with JavaTuples. To work with the Unit class in JavaTuples, you need to import the following package −

import org.javatuples.Unit;

Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Unit Class in Java Tuples, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file.

The following is an example −

Example

import org.javatuples.Unit;
public class Demo {
   public static void main(String[] args) {
      Unit < String > u1 = Unit.with("Science!");
      System.out.println("First: " + u1);
      Unit < String > u2 = u1.setAt0("Mathematics!");
      System.out.println("Copied: " + u2);
      System.out.println("Get Value: " + u2.getValue0());
   }
}

Output

First: [Science!]
Copied: [Mathematics!]
Get Value: Mathematics!
