How increase dynamic array?

How increase dynamic array to save all it's elements?

If its a dynamic array, then it increases automatically, hence the name 'Dynamic' array.

quad64bit, dynamic array, for example such:

Code:

---

int a[];

In Java the length of array types do not change. See the "Arrays" section in Sun's Tutorial.

If you want a simple data structure that will hold an indeterminate number of elements use a List instead.

Code:

---

int a[];

Is not a dynamic array. It is just an array. There is no way to expand an array after the fact, you must either copy the contents to a bigger array or pick a different data structure such as ArrayList.

Code:

---

import java.util.Arrays;

public class Test {
    public static void main(String[] args) {
        int[] values = { 5, 9, 3, 6 };
        System.out.println(Arrays.toString(values));
        // Add 7 to the array.
        int[] temp = new int[values.length+1];
        System.arraycopy(values, 0, temp, 0, values.length);
        temp[values.length] = 7;
        values = temp;
        System.out.println(Arrays.toString(values));
    }
}
