Parameters

set1
Type: Set Class
The set to compare with set2.
set2
Type: Set Class
The set to check.

Return Value

Type: Set Class
A set containing the elements from set1 that are not found in set2.

The two sets to be compared must be of the same type.

The following example creates one set that contains the integers 1, 2, and 3, and one set that contains the integers 2 and 4. The difference method is used to create a set that contains the elements in the first set that are not in the second set (1 and 3).

{ 
    Set is = new Set (Types::Integer); 
    Set is2, is1 = new Set (Types::Integer); 
    ; 
  
    is.add(1); 
    is.add(2); 
    is.add(3); 
    is1.add(2); 
    is1.add(4); 
    is2 = Set::difference(is, is1); 
  
    // prints "{1, 3}" 
    print is2.toString(); 
    pause; 
}
