ArrayList删除集合中某一属性相同的元素方法(推荐)

// list是有重复元素的ArrayList  HashSet hSet =  new HashSet(list);  list.clear();  list.addAll(hSet);

NetWork nw1 = new NetWork();nw1.id = 1;nw1.destip = "192.168.1.3";NetWork nw2 = new NetWork();nw2.id = 2;nw2.destip = "192.168.1.5";NetWork nw3 = new NetWork();nw3.id = 3;nw3.destip = "192.168.1.3";NetWork nw4 = new NetWork();nw4.id = 4;nw4.destip = "192.168.1.4";NetWork nw5 = new NetWork();nw5.id = 5;nw5.destip = "192.168.1.3";mList.add(nw1);mList.add(nw2);mList.add(nw3);mList.add(nw4);mList.add(nw5);

for (int i = 0; i < mList.size()-1; i++) {for (int j = mList.size()-1; j > i; j--) {	if (mList.get(j).destip.equals(mList.get(i).destip)) {mList.remove(j);	}  }	}
