Stuck practicing looping through an array with an error

I am receiving an error in

numbers[i] = new int[];

Java array dimension missing.

I am practicing loops through an array and stuff how to resolve.

public class Main {
    
    public static void main(String[] args) {
        int[] numbers = {10, 35, 17, 95 ,75, 65, 1012,  1, 99, 69};

        for (int element : numbers) {
            System.out.println(element);
        }

        for (int i = 0; i < numbers.length; i++) {
            numbers[i] = new int[];
        }
    }
}

You have to define the array size and its datatype when creating an array in Java.

int numbers[] = new int[10];

Your loops are correctly written, but the line numbers[i] = new int[];, is not needed.

If you want to display the array elements you should implement it as given below.

for (int i = 0; i < numbers.length; i++) {
           System.out.println(numbers[i]); 
        }

Your first part of the code loops through and prints to screen?

public static void main(String[] args) {
    int[] numbers = {10, 35, 17, 95 ,75, 65, 1012,  1, 99, 69};

    for (int element : numbers) {
        System.out.println(element);
    }

Alternatively you could use

for (int i = 0; i < numbers.length; i++) {
       System.out.println(numbers[i]);
    }

You don't need the line

numbers[i] = new int[];

You've already declared the array and assigned values to it
