MSet

Mathematical sets in java.

Examples

Creating MSet

MSet<Long> longSet = MSet.of(1L, 2L, 3L); //from array

ArrayList<String> strings = new ArrayList<>(); //from collection
strings.add("v1");
strings.add("v2");
MSet<String> stringSet = MSet.of(strings);

MSet<Integer> integerSet = IntStream.range(0, 10) //from stream
    .boxed()
    .collect(MSet.toMSet());

Iterating through set :

for (Integer value : set) { //foreach loop
    //...
}

set.stream()    //stream
.forEach(value -> { /* ... */});


Iterator<Integer> iterator = set.iterator(); //iterator
while (iterator.hasNext()) {
    Integer value = iterator.next();
    // ... 
}

Some set operations:

MSet.of(1, 2, 3).union(MSet.of(2, 3, 4)); //union {1,2,3,4}

MSet.of(1, 2, 3).intersection(MSet.of(2, 3, 4)); //intersection {2,3}

MSet.of(1, 2, 3).contains(1); // true
 
MSet.of(1, 2, 3).intersection(MSet.of(2, 3, 4)).contains(1); // false

Universal set bounded operations:

MSet.of(1, 2, 3)
.complement()
.contains(4, MSet.of(1, 2, 3, 4)) //true

MSet.of(1, 2, 3)
.complement()
.contains(1, MSet.of(1, 2, 3, 4)) //false
