Top 5 Java learning tips for competitive programming in 2022

In 2021, there will be 500+ programming languages, and this number keeps on 

increasing day by day. That is why it is not incorrect to say that competition is at a peak. Students and programmers must update themselves with all the new updates about the programming language they are pursuing as their career. 

Apart from this, Java is one of the programming languages that keeps on growing day by day. 

You all might be familiar with the world-class video game called “Minecraft,” a sandbox video game created by Markus “Notch” Persson. Some of you might be aware that it is created using “Java programming language.” 

Yes, it is developed by java programming.

That is why several students and programmers want to learn this language. But they do not have any idea regarding the best Java learning tips for competitive programming.

Not anymore!

We will tell you all the necessary details and tips that will help you get in the competition with the level of Java programming concepts. Moreover, they will help you to crack some of the important questions asked in the competition. So, without wasting more time, let’s get into today’s topic. 

What is the Java programming language?

Java is a general-purpose and object-oriented programming language, and James Gosling designed this language. It is a reliable & fast, and easy-to-learn language. It can run using the JVM (Java Virtual Machine) environment. Java compiler compiles the java source code into bytecode, and it is executed by JVM. 

Moreover, Java is also called a WORA (Write Once, Run Anywhere) programming language. As per the TIOBE Index for December 2021, Java ranked third for developers and is a popular programming language. 

Apart from this, there are numerous reasons to learn this programming language. Some of those are:

What are the best Java learning tips for competition?

It is always helpful for you to use some Java learning tips as they make your learning process easier and interesting. So, without wasting more time, let’s check all the useful tips.

Learn the basics

It is important to know the basics of any programming language. Or it is the perfect way to start something different. Before you start learning java, you should know the basic terms in object, syntax, classes, inheritance, and abstraction. If you are a complete java beginner, maybe the code looks gibberish.

Do not panic; keep learning the language concepts. Get to know the area, and you’ll gradually become familiar with it in less time.

Prefer Group study

If you are a beginner, then this helps you to learn java. Learning java in a group is more effective. As everyone offers their thoughts, you will learn new things about java. And also be able to discuss and solve your code problems on the spot. Get to meet a group of people who are interested in learning Java.

You should also get help from your tutors or read books about java. There are various books available on the market to help you learn Java.

Practice coding

As the old saying that practice makes a man perfect. So, if you are a beginner,  you should keep practicing code daily. Or else, if you don’t practice or study Java code daily, you won’t become a java programmer. This step also helps you to understand and learn java. But in the complex java process, it takes some time. So the best thing to do is that start practicing more code. Remember, practice always makes you better.

 Read Java regularly

As the old saying goes, Consistency is the best teacher. So, you should be consistent for your learning. Try to explore more topics and read continuously about java. This step helps you to maintain your interest in java. Also, you can enhance your coding skills by regularity.  

Patience is the key

To become a master in java, it takes time. Because of the volume of the material learning java is overwhelming. Learning Java is a time-consuming process. Remember that even the best programmers have to start somewhere. So don’t worry about it; just do what you can and keep going. Give it time. Remember that, Patience is key to success.

Shortcut tricks: What are the best Java learning tips for competitive programming?

Although practice is considered the best way to improve performance in the field of programming language, some tricks can help you a lot. These tricks are useful for ensuring the fast debugging and quick implementation of a task. So let’s check the best Java learning tips for competitive programming.

Fast Addition or Division by 2

Multiplying by 2 means shifting all the bits to the left, and dividing by 2 means shifting to the right.

Example: 2 (Binary 10): shifting left 4 (Binary 100) and right 1 (Binary 1)

n = n << 1; // Multiply n with 2 

n = n >> 1; // Divide n by 2 

Calculating the most significant digit

It can be used directly for determining the most important digit of any number log.

Assume that the number is P, then

Let double K = Math.log10(P);

now K = K – Math.floor(K);

int M = (int)Math.pow(10, K);

M will be the most significant digit.

Counting the number of digits directly

Instead of looping, we can use log efficiently to calculate several digits in a number:

No. of digits in N = Math.floor(Math.log10(N)) + 1;

A number is the power of 2

It is quite complex to check this. You need to calculate it as O(logN), but you can solve it as O(v), where v is the number of digits in binary form.  

static boolean isPowerOfTwo (int x)


      return x!=0 && ((x&(x-1)) == 0);   


Use Wrapper class function

If you want to get a number’s radix conversions, then you can use wrapper classes.

class Test {

// Driver method

public static void main(String[] args)


int a = 525;

String binaryA = Integer.toString(a, 2);

System.out.println(“Binary representation”

+ ” of A : ” + binaryA);

String octalA = Integer.toString(a, 8);

System.out.println(“Octal representation”

+ ” of A : ” + octalA);




Binary representation of A : 1000001101

Octal representation of A : 1015
