The contains() method of the Java Decade Tuple
The contains() method is used to search for a value in the Decade Tuple. Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following package
import org.javatuples.Decade;
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 implement the contains() method of the Java Decade Tuple
Example
import org.javatuples.Decade;
public class Demo {
public static void main(String[] args) {
// Tuple with 10 elements
Decade<String, String, String, String, String, String, String, String, String, String> d =
Decade.with("AB","CD", "EF","GH", "IJ","KL", "MN","OP", "QR", "ST");
System.out.println("Elements in the Decade Tuple = "+d);
boolean res1 = d.contains("MN");
System.out.println("Does the value exist in the Decade Tuple? = "+res1);
boolean res2 = d.contains("YZ");
System.out.println("Does the value exist in the Decade Tuple? = "+res2);
boolean res3 = d.contains("QR");
System.out.println("Does the value exist in the Decade Tuple? = "+res3);
}
}Output
Elements in the Decade Tuple = [AB, CD, EF, GH, IJ, KL, MN, OP, QR, ST] Does the value exist in the Decade Tuple? = true Does the value exist in the Decade Tuple? = false Does the value exist in the Decade Tuple? = true
