The contains() method of the Java Octet Tuple
If you want to search whether a particular value exist in the Java Octet Tuple, you need to use the contains() method.
For example, to find the element “Motherboard”, use it like this −
boolean res = oc.contains("Motherboard");As shown above, we have used boolean i.e. the contains() method returns a boolean value; TRUE if the element is in the Tuple, else FALSE.
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 −
Steps − How to run JavaTuples program in Eclipse
The following is an example to work with contains() method 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("Motherboard");
System.out.println("Does the value exist in the Octet Tuple = "+res);
}
}Output
Does the value exist in the Octet Tuple = false
