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
