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:
Output:
Is [GeeksforGeeks] present : true
Is [Geeks, for, Geeks] present : false
Program 2: Using containsAll() with Decade class:
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.
