Strike through methods means that these are deprecated methods. A deprecated method is the one that was for the older version of language and a new, better method has been provided for the same purpose. However the older version is also available for use, for those who have not learned about the new method and upgrading to newer version smoothly step by step.

you can learn about all the deprecated things in java and their new form / syntax Here http://docs.oracle.com/javase/7/docs/api/deprecated-list.html

Use add method instead of addItem like following :

lstA.add("Red");
lstA.add("Blue");
lstA.add("Green");

Getting Strikethrough on method means that method has been Deprecated from API.

@Deprecated have a meaning

A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists. Compilers warn when a deprecated program element is used or overridden in non-deprecated code.
