Java 8: 'Effectively Final' Variables for Thread Safety

Is it important to use the old version of column names like user_name or can we use it as userName, so at Java Entities we don't need to annotate the parameter?

A Tiny Java Mistake That Causes a Compile Error ❗ A Pitfall in Java: Why int i =08 doesn't work? Many developers get confused when Java throws an error for 08. The reason is simple but often overlooked. If a number starts with 0, Java treats it as an Octal number! (Base 8). Octal numbers only allow digits 0–7. That’s why: 08 ❌ 09 ❌ 010 ✔ (equals 8 in decimal) Small Java details like this can save hours of debugging.

I discovered a minor bug in the Java compiler. While the code is valid according to the specification, the Java 25 compiler produces an invalid class file. The issue arises because the lambda code is placed in a static private method of the class, which latter is called by creating with invoke dynamic of a functional delegate. If the method name's availability is tampered with, it can result in bad bytecode, with 2 static method with the same signature being generated. I raised this bug with Java, which can be found here: https://lnkd.in/dKQN9-8Q. Two points of interest regarding this issue are: 1. This behavior started occurring from Java 24 onwards. 2. Prior to Java 24, the compiler would fail, which was an appropriate response. This differs from the approach taken with Anonymous inner classes, where a similar counter mechanism is used, but the counter is increased silently, allowing the code to function correctly. #Java #Java25 #Javac

Java 26 be like: “remember all those times you wrote final and still secretly changed it using reflection? yeah… I saw that 👀.” After years of pretending everything was under control, Java has finally decided that final means FINAL—no backdoor hacks, no sneaky reflection tricks, just pure commitment issues resolved at JVM level #Java26 #FinalMeansFinal

Knowlge Session. Very interesting question. Is JAVA pass by value or pass by reference? If pass by value then when you pass array or list and called function add or remove element from object then calling funcion how it reflect? 😇

Method Overloading in Java -> more than just same method names Method overloading allows a class to have multiple methods with the same name but different parameter lists. Java decides which method to call based on the method signature, which includes: • Number of parameters • Type of parameters • Order of parameters One important detail many people miss: Changing only the return type does not create method overloading. Why does this concept matter? Because it improves code readability and flexibility. Instead of creating different method names for similar operations, we can keep the same method name and let Java decide the correct one during compile time. That’s why method overloading is also called compile-time polymorphism. Small concepts like this form the foundation of how Java’s Object-Oriented Programming model really works. #Java #JavaProgramming #OOP #BackendDevelopment #CSFundamentals

Day 25 -What I Learned In a Day(JAVA) Today I learned about conditional and control statements in Java, which allow programs to make decisions, repeat tasks, or alter the flow of execution. Three Types of Control Statements in Java: *Decision Statements (Decision Making) Used to execute code based on conditions. Examples: if / if-else / nested if-else – Executes code if condition is true or false. switch – Executes code based on the value of a variable. *Looping Statements: Used to repeat a block of code multiple times. Examples: for, while, do-while. *Jump Statements: Used to alter the normal flow of execution in loops or methods. Examples: break, continue, return. Today I Practiced 20 questions based on the decision making statement if,else.
