## What are the basic data structures?

8 Common Data Structures every Programmer must know Arrays. An array is a structure of fixed-size, which can hold items of the same data type. Linked Lists. A linked list is a sequential structure that consists of a sequence of items in linear order which are linked to each other. Stacks. Queues. Hash Tables. Trees. Heaps. Graphs.

**What is algorithm in Java?**

An algorithm is unambiguous finite step-by-step procedure which is given input to produce output. Typically algorithms are used to solve problems such that for every input instance it produces the solution (sometimes this is not true, it depends on the goal for the problem). We can implement algorithms in Java.

**What is structure in Java?**

Structure of Java Program. Structure of a java program is the standard format released by Language developer to the Industry programmer. Sun Micro System has prescribed the following structure for the java programmers for developing java application. A package is a collection of classes, interfaces and sub-packages.

### What are data structures class?

Overall, data structures tends to be a relatively easy class. However, there is a lot to learn, it is a very important class and there are some tricky aspects to it. There are actually a number of factors that will impact the difficulty of the class for you. However, there are a number of things that you can do to make it much easier.

**What is the best book for data structures?**

Introduction to Algorithms by Thomas H. Cormen.

**What is the best book to learn algorithms?**

Introduction to Algorithms by Thomas H. Corman This is one of the most popular algorithm books, but be aware that it contains a heavy dose of theory. Algorithms by Robert Sedgewick & Kevin Wayne This was my preferred resource on algorithms for a long time, it still is but now I see it less often than The Algorithm Design Manual by Steve S.
