A summary of several types of iterative accesses to the collection object list in Java is as follows
1 classic for loop
public static void main(String[] args) { List<String> list = new ArrayList(); list.add("123"); list.add("java"); list.add("j2ee"); System.out.println("========== Classic for loop==============="); for(int i=0; i<list.size();i++){ System.out.println(list.get(i)); } }2 Enhanced for loop
public static void main(String[] args) { List<String> list = new ArrayList(); list.add("123"); list.add("java"); list.add("j2ee"); System.out.println("============= for loop in Java1.6==============="); for(String s:list){ System.out.println(s); } }3Iterate usage
public static void main(String[] args) { List<String> list = new ArrayList(); list.add("123"); list.add("java"); list.add("j2ee"); System.out.println("==========Iterate loop=============); Iterator<String> iter = list.iterator(); while(iter.hasNext()){ System.out.println(iter.next()); } }The above article briefly discusses several loop accesses to the collection object list in Java are all the content I share with you.
