set array as an object properties

Question

i don't know how to set a specific array (with values of lets say {1,2,3,4}) as an object property? (this is the only property)

i tried this in my class as a constructor (and i don't want to use initializing constructor)

public class Arrays {

    public int [] arr = {2,3,4,5};

    public Arrays (int[] arr ) {

        this.arr = arr; }

but what do i put in the brackets ?

Arrays a = new Arrays ();

thanks!

You can do it like this:

Arrays a = new Arrays(int[x]{1,2,3,4,5});

Hope i could help you.

You could do

MyArrays arrays = new MyArrays(new int[] {1,2,3,4,5});

You must make new instance in place where you call your constructor.

Arrays a = new Arrays (new int[]{1,2});

If you want the object to initialize its own array:

public class Arrays {
    public int[] arr = {1,2,3,4,5};
}

And use it like this:

Arrays a = new Arrays();

If you want the caller to initialize an array and pass it to the constructor:

public class Arrays {
    public int[] arr;
    public Arrays(int[] arr) {
        this.arr = arr;
    }
}

And use it like this:

int[] arr = {1,2,3,4,5};
Arrays a = new Arrays(arr);
