Java 8 IntUnaryOperator - top ranked examples from Open Source projects

These code examples were ranked by Codota’s semantic indexing as the best open source examples for Java 8 IntUnaryOperator class.

This code example shows how to use the following methods:applyAsInt
    private IntUnaryOperator fib =
            (n) -> (n < 2) ? n : fib.applyAsInt(n - 1) + fib.applyAsInt(n - 2); 
 
    @Test
    public void test10() { 
        Assert.assertEquals(55, fib.applyAsInt(10));
    } 
 
    private static IntUnaryOperator fib_static =
            (n) -> (n < 2) ? n : fib_static.applyAsInt(n - 1) + fib_static.applyAsInt(n - 2); 
 
    @Test
    public void test10_static() { 
        Assert.assertEquals(55, fib_static.applyAsInt(10));
    } 
 
//    @Test 
//    public void test10_bad() { // should not compile 
//        IntUnaryOperator fib = 
//                (n) -> (n < 2) ? n : fib.operate(n - 1) + fib.operate(n - 2);
