Java Data Structures
In this blog, I will teach you all that you need to know about Java data structures. Data
structures are ways in which we organize and manipulate data. Java has various different
classes available to us that help us manage data, and it's essential to know how they work.
Everything you learn here will apply to pretty much all versions of Java.
Arrays
Arrays are the building blocks of many other data structures that Java has to offer. An array
is a list of cells, or a bucket or list of buckets where you define the size. Arrays are really
fast for data retrieval because you basically just define the data structure or the array itself.
If you want to access a particular element in your array, the index starts with zero.
Java Array Classes:
Java provides classes to work with arrays
Main method is where all the examples will be shown
Creating an Array:
To create an array, you basically have to specify the data type. For example:
int[] myArray = new int[10];
The code above creates an integer array called 'myArray' with a size of 10. Similarly, you
can create a string array:
String[] myStringArray = new String[5];
The code above creates a string array called 'myStringArray' with a size of 5.
