Hyder This is the of the dodo. 2
And welcome to another new chapter in this chapter. 3
We will continue strengthening our language basics. 4
Nice thing about this chapter is we will also for the first time look at an important design principle 5
that is necessary for building well well-designed software which is our ultimate goal. 6
So it's going to be some interesting stuff. 7
Let's see what we are going to cover in this chapter 8
we begin the chapter by looking at the July 8. 9
We would also explore it on the article's website Gusterson API are arranged into something called package's 10
So next we'll look at packages which provide meaningful organization of classes based on their functionality 11
we will see how we can access classes and packages and also how we can create our own packages and also 12
how we should name packages. 13
And with regards to naming packages we will also look at some recommended naming conventions from one 14
of the items in Effective Java next we will look at strings which basically represent text string manipulation 15
is one of the most common activities in programming we will look at how strings are stored internally 16
and we will also look at some performance implications which may need to be aware of when manipulating 17
strings so it's going to be some pretty in-depth coverage just strings next we will look at access levels 18
which are critical for writing well design software but the craft world is on software there are lots 19
of design principles and people look at one of them called Information Hiding we will specifically look 20
at a couple of very important effort of Didymus And as always we will also write some good best most 21
of the stuff we are going to learn in this chapter. 22
So that's up on the agenda. 23
And these topics are nicely connected with each other. 24
For example to understand access levels you need to know what packages are and you understand information 25
hiding you need to know what access levels are so it's going to get interesting stuff. 26
Let's go ahead and get started with the chapter
