Converting List to List June 22, 2022 by Eiji I have a list of integers, List and I’d like to convert all the integer objects into Strings, thus finishing up with a new List . Naturally, I could create a new List and loop through the list calling String.valueOf() for each integer, but I was wondering if there was a better (read: more automatic ) way of doing it? Using  you could use the transform method in the  class import com.google.common.collect.Lists; import com.google.common.base.Functions List integers = Arrays.asList(1, 2, 3, 4); List strings = Lists.transform(integers, Functions.toStringFunction()); The List returned by transform is a view on the backing list – the transformation will be applied on each access to the transformed list. Be aware that Functions.toStringFunction() will throw a NullPointerException when applied to null, so only use it if you are sure your list will not contain null.

Answer :

Using  you could use the transform method in the  class

import com.google.common.collect.Lists;  import com.google.common.base.Functions    List integers = Arrays.asList(1, 2, 3, 4);    List strings = Lists.transform(integers, Functions.toStringFunction());  

The List returned by transform is a view on the backing list – the transformation will be applied on each access to the transformed list.

Be aware that Functions.toStringFunction() will throw a NullPointerException when applied to null, so only use it if you are sure your list will not contain null.
