There are a few syntax errors in the code. Here's the corrected version:

class TestIt {
    public static void main(String[] args) {
        int[] myArray = {1, 2, 3, 4, 5};
        ChangeIt.doit(myArray);
        for (int j = 0; j < myArray.length; j++) {
            System.out.print(myArray[j] + " ");
        }
    }
}

class ChangeIt {
    static void doit(int[] z) {
        z = null;
    }
}

In the main method, I have corrected the syntax for the array initialization and added missing curly braces for the for loop. In the ChangeIt class, I have corrected the method name from "dort" to "doit"
