是否有Java中的方法通过指定开始和结束索引来获取从Arraylist到另一个ArrayList的对象列表?
Yes you can use the subList
method :
List<...> list2 = list1.subList(startIndex, endIndex);
This returns a view on that part of the original list, it does not copy the data.
If you want a copy:
List<...> list2 = new ArrayList<...> (list1.subList(startIndex, endIndex));
/create an ArrayList object
ArrayList arrayList = new ArrayList();
//Add elements to Arraylist
arrayList.add("1");
arrayList.add("2");
arrayList.add("3");
arrayList.add("4");
arrayList.add("5");
/*
To get a sub list of Java ArrayList use
List subList(int startIndex, int endIndex) method.
This method returns an object of type List containing elements from
startIndex to endIndex - 1.
*/
List lst = arrayList.subList(1,3);
//display elements of sub list.
System.out.println("Sub list contains : ");
for(int i=0; i< lst.size() ; i++)
System.out.println(lst.get(i));
