About the Author:<\/strong><\/em>\u00a0N. Caleb Jebadurai, a student of the Shepherd Institute of Technology, talks about his internship experiences at DRDO before and after he did an online training.<\/em><\/p>\n

I came across Internshala in my 3rd year while looking for an online winter training. After checking out the content of the trainings, I enrolled myself in Core Java<\/a>. <\/span>I started with the Java training since I had a fair knowledge of the basic concepts of Java. The training introduced me to the IntelliJ IDE and taught me the basic concepts of Java – its variables, data types, and operators. Next, I learnt about interfaces, arrays, and strings along with classes and objects. The training helped me understand how\u00a0UI could be designed\u00a0using FXML. The third module was about the concepts of object-oriented programing. I wasn\u2019t familiar with OOPs at all but gained a fair knowledge of the same during the training. Moving forward, I learnt about JVM, garbage collector, and exceptional handling. I also learnt to develop a professional desktop software from scratch while working on the \u2018Connect Four\u2019 project. <\/span>I was facing a difficulty in keeping up with time due to my academic schedule and was disappointed\u00a0at\u00a0not being able to complete the training in time. I wrote to Internshala support team, and generously enough, they extended my training. I was pretty satisfied with the experience I had with Internshala, so I did two more trainings, viz.\u00a0Programming with Python<\/a>, and Android app development<\/a>.<\/span><\/p>\n

My semester examination started shortly after I completed my trainings, and then I took a break. Once my exams were over, I decided to rebuild the project that I had worked on during my internship with DRDO in my 2nd year. <\/span>I was asked to build a desktop software that would load data from text files and display them as four graphs. Since I didn\u2019t have any knowledge of UI in Java at that time, I had\u00a0copy pasted a code snippet from the internet and submitted my project. However, it had a lot of glitches. <\/span>The project had four graphs in separate frames, and I had to close each graph individually. Also, I had to restart the software to load new data and was unable to create a JAR package that could work on different systems. Now that I had learnt Java, I modified its UI such that all the graphs were visible on one frame in a four-tabbed pane. I added a menu to load new data without having to restart the application and changed all the naming conventions in the recommended way. I added a few other features to this application for beautifying the project.\u00a0<\/span><\/p>\n

After modifying the project,\u00a0I met with a scientist at DRDO and secured another 3-month internship at DRDO. I am now working on a machine learning algorithm,\u00a0called Principal Component Analysis<\/em>, that requires me to work on Java and Python. I am coding this algorithm from scratch and thanks to Internshala, I now understand the long lines of code which once seemed alien to\u00a0me; they\u00a0don\u2019t give me nightmares anymore. The concepts of for loops, if-else, functions, and arrays that I had learnt as a part of the training are proving to be quite beneficial for me. I am able to understand the complexity of the algorithm and have devised the algorithm such that it imports data from a .txt file to a 2D NXM matrix and performs generalization, normalization, transpose, multiplication, etc. \u00a0\u00a0<\/span><\/p>\n
