Example 1 with MutableDoubleBag

use of org.eclipse.collections.api.bag.primitive.MutableDoubleBag in project eclipse-collections by eclipse.

the class PrimitiveStreamsTest method toDoubleBag.

@Test
public void toDoubleBag() {
    MutableDoubleBag bag = PrimitiveStreams.mDoubleBag(DoubleStream.of(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0));
    Assert.assertEquals(DoubleBags.mutable.ofAll(IntInterval.oneTo(10).asLazy().collectDouble(i -> (double) i)), bag);
    Assert.assertEquals(DoubleBags.immutable.ofAll(DoubleStream.of(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0)), bag);
