Mastering programming language is the most important stuff as a software engineer starts the career. My suggestions are as the following: - learn the fundamental statements of a specific language, e.g. variable declaration, condition check, looping, recursive, data operations - practice with certain classic patterns, e.g. time expiration cache, message queue, - try to optimize the codes you have written by considering either space or time complexities.

Java - focus on the following: 1. Understand inheritance and when to use it. (OOP) 2. Understand lambdas and when and how to use them. (Java 8 Streams) 3. Know how to create Javadoc documentation. 4. Know how to test and debug Java code.

An analogy that really helped me when I started programming was that a program is generally like a recipe : - There are ingredients that have a temperature and other properties (data/variables) - There are steps that you need to follow in the right order (instructions) - It might happen that a step is optional, or only needs to be performed if a condition is met (conditional statements) - There are steps that you'll need to perform until some condition is met (loops) - Sometimes, the recipe will refer to another recipe (functions) - Maybe you'll want to change the recipe to your taste, or adapt it to the ingredients you currently have (inheritance) Next thing you know, cooking is Turing complete!

1. Understand Core Concepts: - Data Types - Control Structures - Functions - Object-Oriented Programming (OOP) 2. Practice Simple Programs: - Sorting Algorithms: Implement basic sorting algorithms like bubble sort or insertion sort. These exercises help you understand algorithmic thinking and efficiency. - String Manipulations: Write programs to manipulate strings, such as reversing a string or checking if a string is a palindrome. 3. Importance for Interviews: - Assess Understanding: Interviews often focus on basic concepts to gauge your understanding of the language’s core principles. Be prepared to explain and demonstrate these fundamentals.

Solidify your understanding of core programming concepts like data structures, algorithms, object-oriented programming, and common design patterns. Having a strong grasp of fundamentals will make learning specific languages easier.
