JavaTuples containsAll() method
Last Updated :

The containsAll() method in org.javatuples is used to check whether a collection of values is present in the TupleClass, given as parameters. This method can be used for any tuple class object of the javatuples library. It returns a boolean value that is true or false based on the presence of that collection of values in the TupleClass.
Method Declaration:
public final boolean containsAll(Object... value)
Syntax:
boolean result = TupleClassObject.containsAll(X value1, X value2, ...)
OR
boolean result = TupleClassObject.containsAll(X[] values)
Parameters: This method takes value or values as parameter where:
- X– represents the datatype of values in the parameter.
- TupleClassObject– represents the JavaTuple Class object used like Unit, Quintet, Decade, etc.
Return Value: This method returns true if the parameter value are present in the tuple. Else it returns false
Below programs illustrate the various ways to use containsAll() method:
Program 1: Using containsAll() with Unit class:
import java.util.*;
import org.javatuples.Unit;
class GfG {
public static void main(String[] args)
{
Unit<String> unit = Unit.with( "GeeksforGeeks" );
boolean res;
String[] check = { "GeeksforGeeks" };
res = unit.containsAll(check);
System.out.println( "Is " + Arrays.toString(check) + " present : " + res);
String[] check1 = { "Geeks" , "for" , "Geeks" };
res = unit.containsAll(check1);
System.out.println( "Is " + Arrays.toString(check1) + " present : " + res);
}
}

Output:
Is [GeeksforGeeks] present : true
Is [Geeks, for, Geeks] present : false
Program 2: Using containsAll() with Decade class:
import java.util.*;
import org.javatuples.Decade;
class GfG {
public static void main(String[] args)
{
Decade<String, String, String, String, String,
String, String, String, String, String>
decade = Decade.with( "Geeks" ,
"for" ,
"Geeks" ,
"A" ,
"Computer" ,
"Science" ,
"Portal" ,
"for" ,
"Geeks" ,
"RishabhPrabhu" );
boolean res;
String[] check = { "Geeks" , "for" , "Geeks" };
res = decade.containsAll(check);
System.out.println( "Is " + Arrays.toString(check) + " present : " + res);
String[] check1 = { "Geeks" , "not" , "for" , "Geeks" };
res = decade.containsAll(check1);
System.out.println( "Is " + Arrays.toString(check1) + " present : " + res);
}
}

Output:
Is [Geeks, for, Geeks] present : true
Is [Geeks, not, for, Geeks] present : false
Note: Similarly, it can be used with any other JavaTuple Class.
