clone array

Et 2 dimensionelt array i Java er i virkeligheden et array
af arrays, så den har tilsyneladende kun klonet i et niveau.

Se f.eks.:

public class TwoDimClone {
    public static void main(String[] args) throws Exception {
        int[] one = new int[]{5,5};
        int[] oneClone = (int[])one.clone();
        one[1]=0;
        System.out.println(oneClone[1]);
        int[][] two = new int[][]{{5,5,5},{5,5,5},{5,5,5}};
        int[][] twoClone = (int[][])two.clone();
        two[1][1] = 0;
        System.out.println(twoClone[1][1]);
        int[][] three = new int[][]{{5,5,5},{5,5,5},{5,5,5}};
        int[][] threeClone = new int[three.length][];
        for(int i = 0; i < threeClone.length; i++) {
            threeClone[i] = (int[])three[i].clone();
        }
        three[1][1] = 0;
        System.out.println(threeClone[1][1]);
    }
}

fanerme smukt :) takker
vil du også ha point ?

jo tak
