How to convert List<String> to List<Long>

Question

Having list of strings and want to convert into list of long. Please provide me some example.

Answer 1

At this point I can think of below as a solution for you.

List<Long> longList = new ArrayList<Long>();

longList.add(1L);

longList.add(2L);

 

List<String> stringList = new ArrayList<String>();

 

for(Long _long : longList)

stringList.add(String.valueOf(_long));

 

Hope that helps.
