Java one liner for loop

Question

Here , someone made a one-liner for loop in Python.

Another example is this:

someList = [f(i) for i in range(16)]

which would be a one-liner for this code:

someList = []
for i in range(16):
    someList.append(f(i))

or, in Java:

int[] someList = {}
for (int i = 0; i < 16; i++) {
    someList = append(someList, f(i));
}

such that f is some function that will return an integer.

Now, is there an equivalent one-liner in Java?

Note: Currently, I am using Processing, which is similar to Java, so, any code written in Java might be usable in Processing.

Answer 1

Java 8的IntStream拯救：

int[] someList = IntStream.range(0, 16).map(i -> f(i)).toArray();

Answer 2

Traditional

int [] arr = {1,4,6,7,2};

for(int i = 0; i< arr.length; i++){

System.out.println(arr[i]);

}

One Line

for (int val : arr) { System.out.println(val); }
