Sets.difference() de Guava devuelve una vista no modificable de la diferencia de dos conjuntos.
Sintaxis:
public static <E>
Sets.SetView<E>
difference(Set<E> set1,
Set<?> set2)
Valor devuelto: este método devuelve un conjunto que contiene todos los elementos contenidos en conjunto1 y no contenidos en conjunto2.
Nota: Set2 también puede contener elementos que no están presentes en set1, estos simplemente se ignoran. El orden de iteración del conjunto devuelto coincide con el del conjunto1.
Ejemplo 1:
// Java code to show implementation of
// Guava's Sets.difference() method
import com.google.common.collect.Sets;
import java.util.Set;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating first set named set1
Set<Integer>
set1 = Sets.newHashSet(1, 2, 3, 4, 5, 6);
// Creating second set named set2
Set<Integer>
set2 = Sets.newHashSet(1, 3, 5, 7);
// Using Guava's Sets.difference() method
Set<Integer>
diff = Sets.difference(set1, set2);
// Displaying the unmodifiable view of
// the difference of two sets.
System.out.println("Set 1: "
+ set1);
System.out.println("Set 2: "
+ set2);
System.out.println("Difference between "
+ "Set 1 and Set 2: "
+ diff);
}
}
Producción:
Set 1: [1, 2, 3, 4, 5, 6] Set 2: [1, 3, 5, 7] Difference between Set 1 and Set 2: [2, 4, 6]
Ejemplo 2:
// Java code to show implementation of
// Guava's Sets.difference() method
import com.google.common.collect.Sets;
import java.util.Set;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating first set named set1
Set<String>
set1 = Sets
.newHashSet("H", "E", "L", "L", "O", "G");
// Creating second set named set2
Set<String>
set2 = Sets
.newHashSet("L", "I", "K", "E", "G");
// Using Guava's Sets.difference() method
Set<String>
diff = Sets.difference(set1, set2);
// Displaying the unmodifiable view of
// the difference of two sets.
System.out.println("Set 1: "
+ set1);
System.out.println("Set 2: "
+ set2);
System.out.println("Difference between "
+ "Set 1 and Set 2: "
+ diff);
}
}
Producción:
Set 1: [E, G, H, L, O] Set 2: [I, K, L, E, G] Difference between Set 1 and Set 2: [H, O]
