Search for a value in Java Octet Tuple

Java 8Object Oriented ProgrammingProgramming

To search for a value in Java Octet Tuple, you need to use the contains() method. The method returns a Boolean value stating whether the element set as a parameter exists in the values set in Octet Tuple or not. Let us first see what we need to work with JavaTuples. To work with Octet class in JavaTuples, you need to import the following package −

import org.javatuples.Octet;

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 search for a value in Java Octet tuple −

Example

import org.javatuples.Octet;
public class Demo {
   public static void main(String[] args) {
      Octet<String, String, String, String, String, String, String, String> oc = Octet.with(
         "laptop", "desktop","mobile", "tablet","monitor", "LCD","LED", "OLED");
      boolean res = oc.contains("tablet");
      System.out.println("Does the value exist in the Octet Tuple = "+res);
   }
}

Output

Does the value exist in the Octet Tuple = true

Above, we have set the elements in the Octet Tuple −

Octet<String, String, String, String, String, String, String, String> oc = Octet.with("laptop", "desktop","mobile", "tablet","monitor", "LCD","LED", "OLED");

Then, we have used the contains() method to search for an element −

boolean res = oc.contains("tablet");
