    final int[] sum = new int[1];
    IntStreams.range(1, 10).filter(new IntPredicate() {

        @Override
        public boolean test(int i) {
            return i % 2 == 0;
        }
    }).forEach(new IntConsumer() {

        @Override
        public void accept(int i) {
            sum[0] = sum[0] + i;
        }
    });
    assertEquals(sum[0], 20);
}

Example 2 with IntPredicate

use of java8.util.function.IntPredicate in project streamsupport by stefan-zobel.

the class IntPrimitiveOpsTests method testParForEach.

@Test(groups = { "serialization-hostile" })
public void testParForEach() {
    final AtomicInteger ai = new AtomicInteger(0);
    IntStreams.range(1, 10).parallel().filter(new IntPredicate() {

        @Override
        public boolean test(int i) {
            return i % 2 == 0;
        }
    }).forEach((IntConsumer) new IntConsumer() {

        @Override
        public void accept(int i) {
            ai.addAndGet(i);
        }
    });
    assertEquals(ai.get(), 20);
}

@Test(groups = { "serialization-hostile" })
public void testTee() {
    final int[] teeSum = new int[1];
    long sum;
    sum = IntStreams.range(1, 10).filter(new IntPredicate() {

        @Override
        public boolean test(int i) {
            return i % 2 == 0;
        }
    }).peek(new IntConsumer() {

        @Override
        public void accept(int i) {
            teeSum[0] = teeSum[0] + i;
        }
    }).sum();
    assertEquals(teeSum[0], sum);
}

public void testMap() {
    long sum = IntStreams.range(1, 10).filter(new IntPredicate() {

        @Override
        public boolean test(int i) {
            return i % 2 == 0;
        }
    }).map(new IntUnaryOperator() {

        @Override
        public int applyAsInt(int i) {
            return i * 2;
        }
    }).sum();
    assertEquals(sum, 40);
}
