“To win at Java programming, you need to be able to look at a problem and break it down into smaller parts and solve each part individually. When you can solve these smaller problems and put them together, you can solve any problem!”
“The most important tip I have for learning Java is to write as much code as possible. The more code you write, the better you will understand how to use it.”
“Programming is hard. If you don’t build something every single day, you will not become a good programmer. It takes years of practice.”
“I would suggest picking one thing that is interesting to you or one project that looks like fun and just go for it! Don’t worry about being perfect; just get started.”
As a Java programmer, you should always be on the lookout to expand your knowledge and learning. The only way to keep up with the ever-changing tech world is to keep an open mind and always look for opportunities to learn something new.
To get started, we reached out to a few polyglots in the Java community to find out what they’d recommend to aspiring programmers. We asked them to share their thoughts on how they stay motivated while learning Java and their favorite tools and resources that help them be successful.
Here are some of their best tips:
Why are you here?
Are you here to discover the best tips for Java programming or to improve your skills? We can assume that you are here to learn from the masters, the ones who have a deep and comprehensive understanding of Java. You might be one of those people who want to become a top-notch programmer or a developer for your career advancement. Well, we got good news for you!
Before we get started with the tips, let’s start with the basics. Java is one of the most popular programming languages in the world, according to Github and Stack Overflow. The language is used by millions of developers and billions of devices around the world and is one of the forces that drives innovation in technology. Since its release in 1995, it has been among the top preferred programming languages for developing applications, websites, software, and games. It is also an essential language for Android apps development as well as an alternative to C++ for many systems software development projects. Java is not just a programming language but also an ecosystem that includes a huge number of libraries and frameworks which make it possible for developers to build complex systems quickly.
Becoming a competent Java programmer means that you need to master several skills like object-orientation, concurrency, test-driven
Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It has become the world’s most popular programming language.
Java is free to download and used in a variety of computing platforms from embedded devices and mobile phones on the low end, to enterprise servers and supercomputers on the high end.
Java is a creation of Sun Microsystems (now owned by Oracle). It was born in 1991 but came into public domain in 1995. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities.
James Gosling developed Java at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as core component of Sun Microsystems’ Java platform (Java 1.0 [J2SE]).
Java’s early slogan was “Write Once, Run Anywhere”, which was intended to emphasize its cross-platform capabilities.
A few weeks ago, the HackerRank community was challenged to solve a problem based on an interview question from Google. The question was very straightforward: “Given two strings s and t, determine whether some anagram of t is a substring of s. For example: if s = “udacity” and t = “ad”, then the function returns True. Your function definition should look like: question1(s, t) and return a boolean True or False.”
Hundreds of people participated in this challenge and submitted many interesting solutions. We were impressed with how many different ways there are to solve it! Here are just a few, for example:
– Using Python dictionary
– Using Java HashMap
– Using C++ map
– Using C++ STL sort() and equal() functions
– Using JavaScript objects
– Using Groovy map
This month we want to see how you would approach the same problem if your chosen language were Java. Write a function that takes two strings as parameters and returns true if one string is an anagram of another string, otherwise returns false.
Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them. As of 2016, Java was one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of

public class Solution {
public static void main(String[] args) {
int i = 4;
double d = 4.0;
String s = “HackerRank “;
Scanner scan = new Scanner(System.in);
/* Declare second integer, double, and String variables. */
/* Read and save an integer, double, and String to your variables.*/
// Note: If you have trouble reading the entire String, please go back and review the Tutorial closely.
int j=scan.nextInt();//The nextInt() method scans the next token of the input as an int.
double e=scan.nextDouble();//The nextDouble() method scans the next token of the input as a Double.
scan.nextLine();//To get it to work right I had to add a scan.nextLine() after my scan.nextInt() and scan.nextDouble(). The problem is that on this line: int j=scan.nextInt(); it reads only the Int value and not the enter key (or “\n”) character from your previous input so when you call nextLine it’s
