How to select the next element of a Java Collection object?

Question

Java

Good day! How to get the next element of a collection? There is a collection of objects, the object has two fields name and code (respectively, the get and set methods for them), the names need to be compared with each other, this is the responsibility of the method that takes two lines (the line and the line following it)

List<SomeClass> list = new ArrayList<SomeClass>();
        for (SomeClass str : list) {
         \\Строку я могу получить, но как получить следующую за ней строку?
         someMethod(str.getName(), /*?????*/);
    }

Thanks in advance!

Answer 1

In this case, you need to use a regular loop, not a for-each loop

for(int i=0; i < list.size()-1; i++){
     someMethod(list.get(i), list.get(i+1));
}

Answer 2

Learn iterators. In your case, you need a while and next loop to get the next element.
