I suppose it should be possible if you know the size you want to increment before hand as shown from the example below. If you do not know the size before hand it is better to use structures like ArrayList or Vector. Hope this answers your query



public class Test {



static int num[] = new int[8];



public static void main(String[] args)
{


int i = 0;



System.out.println("length before change is :" +num.length);



for(i = 0;i < num.length;i++)
{


num[i] = i;


System.out.println("element is:" +num[i]); }



testing();




System.out.println("after length is :" +num.length);




for(int j = i; j < num.length;j++){


num[j] = j;


System.out.println("element is:" +num[j]);
}


}



public static void testing() {


num = new int[20];


}


}
