List集合与Map集合的遍历
/*List集合赋值*/ List<String> strList = new ArrayList<String>(); strList.add("1"); strList.add("2"); strList.add("3"); strList.add("4"); strList.add("5"); /*List集合遍历*/ Iterator<String> it = strList.iterator(); while(it.hasNext()){ System.out.println(it.next()); } /*Map集合赋值*/ Map<String, String> strMap = new HashMap<String, String>(); strMap.put("1", "测试一"); strMap.put("2", "测试二"); strMap.put("3", "测试三"); strMap.put("4", "测试四"); strMap.put("5", "测试五"); /*Map集合遍历*/ for(Map.Entry<String, String> entry : strMap.entrySet()){ System.out.println("key= " + entry.getKey() + " and value= " + entry.getValue()); }
