States that the index must be between 0 and list size inclusive but this is not true.

• final List<String>myKidName = Arrays.asList("JOHN","STEPHEN","ORTIZ","RONDON");
  System.out.println(myKidName.get(0)+" "+myKidName.get(myKidName.size()));

This is throwing

Code: Select all

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
	at java.util.Arrays$ArrayList.get(Arrays.java:3841)

Because the size is in range [0..3] and the size inclusive is not true must be inclusive and exclusive

[admin]

The complete sentence that I see is, "Remember that for the get and the remove methods, the index must be between 0 and the
list’s size1 minus 1 (both inclusive)." (There is a typo size1)
This is correct. size minus 1 is indeed inclusive.

[javiut]

i mean this line.

The index value must lie between 0 and list current size (Both inclusive) otherwise an Index just after the 13 for each paragraph.

The index always must be between 0 and list.size()-1 not only for get and remove methods but for all the methods which is a index is passed as parameters except the indexOf this is throwing exception as well you can see is a set method.

final List<String>myKidName = Arrays.asList("JOHN","STEPHEN","ORTIZ","RONDON");
System.out.println(myKidName.set(myKidName.size(),"LA ESTRELLA"));

But this is not throwing any.

Code: Select all

        final List<String>myKidName = Arrays.asList("JOHN","STEPHEN","ORTIZ","RONDON");
        System.out.println("myKidName = " + myKidName.indexOf(Integer.MAX_VALUE));
