pass array to method Java

Question

How can I pass an entire array to a method?

private void PassArray() {
    String[] arrayw = new String[4];
    //populate array
    PrintA(arrayw[]);
}

private void PrintA(String[] a) {
    //do whatever with array here
}

How do I do this correctly?

Answer 1

You do this:

private void PassArray() {
    String[] arrayw = new String[4]; //populate array
    PrintA(arrayw);
}

private void PrintA(String[] a) {
    //do whatever with array here
}

Just pass it as any other variable.
In Java, arrays are passed by reference.
