静态方法不能访问非静态方法，非静态方法则是可以访问静态方法.

PS：ArrayList方法有：remove，removeAll，add。addAll，get、

package collection接口测试;import java.util.*;public class ArraylistTEST{int num;ArraylistTEST(){this.num=0;}public  static int  ZSS(int x){//Integer tempInteger=new Integer(x);return x;} ArraylistTEST t=new  ArraylistTEST();public static void main(String[] args) {  ArrayList list =new ArrayList();  ArrayList li=new ArrayList();  for(int i=1;i<=7;i++)  {  li.add(new Integer(i));  //li.add(i);  } int x=ZSS(3); System.out.println(list.toString()); System.out.println(li.toString()); yimiaovpn[]shuzu=new yimiaovpn[4]; for(int i=0;i<4;i++) { shuzu[i]=new yimiaovpn(); shuzu[i].jia(); } System.out.println(shuzu[3].num);  /*list.add(new Integer(4));  li.add(new Integer(33));  li.remove((4));  System.out.println(li.toString());  list.set(0,new Integer(11));  System.out.println(list.toString());*/}}class yimiaovpn{static int num=1;public static int mallo(int x){return x;}public static void jia(){num++;}}
