简单扩充数组方法

public static void main(String[] args) {

           // TODO Auto-generated method stub

int[] a=new  int[3];

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

if(a.length==(i+1)){

int[] c=new int[a.length+1];

a=c;

}

if (a.length==10) {//根据需求设定

break;

}

}

System.out.println(Arrays.toString(a));

}
