Just wondering how to add another object to a fixed object array.Would you change the length of the array?
object length is 43
for(int i=0;i<count;i++){
object[count] =new Movie(movieID,movieTitle,Director,Writer,Duration,Genre,Classification,releaseDate,Rating);
}
this was the loop to create the first array of objects with a length of 43 How would you use a separate method to add another object to this array without using an array list?
You would definitely need to reassign the original array, as arrays do have a fixed size. This tiny example does illustrate how it could be done.
public class A {
private int i;
public A(int i) {
this.i = i;
}
public static void main(String[] args) {
// Original array with the size 1;
A[] arr = new A[1];
// One default item
arr[0] = new A(0);
// Reassign array here, use a method returning a new instance of A[]
arr = add(arr, new A(1));
// just for printing.
for(A a : arr) {
System.out.println(a.i);
}
}
public static A[] add(A[] inputArr, A newItem) {
// The array will have another item, so original size + 1
A[] buffer = new A[inputArr.length+1];
// Copy the original array into the new array.
System.arraycopy(inputArr, 0, buffer, 0, inputArr.length);
// Add the new item at the end
buffer[buffer.length-1] = newItem;
// Return the "increased" array
return buffer;
}
}
The output now shows you have two items in the array.
O/P:
0
1
All in all it would be better to use a List here, but as you don´t want it i hope that this example can guide you to a way of doing it with arrays.
you can simple send the reference of the array to a method, then create a new array with size+1 , fill the array and return it, though this is a bad practice , if you need dynamic size just use arraylist
