Let's say I have a List,
Arrays.asList("A","B","C","D");
Is there a convenience method in Java that allows me to check this List to see if the elements C and D are on this list in that order?
Something along the lines of:
Collections.containsOrderedElements(list,"C","D");
Collections.containsOrderedElements(list,"A","B","C");
Where the above methods will return true but
Collections.containsOrderedElements(list,"A","C");
will not?
There is a method in the java.util package that can help (Collections.indexOfSubList(sourceList, subList)):
List<String> list = Arrays.asList("A", "B", "C", "D");
System.out.println(Collections.indexOfSubList(list, Arrays.asList("C", "D")) >= 0);
System.out.println(Collections.indexOfSubList(list, Arrays.asList("A","B","C")) >= 0);
System.out.println(Collections.indexOfSubList(list, Arrays.asList("A", "C")) >= 0);
It prints:
true
true
false
