Java var Explained ✅ | Local Variable Type Inference (Java 10 Feature)

Java is a strongly typed language — every variable must have a type. But since Java 10, developers can use var for local variable type inference (LVTI). Many beginners confuse it with JavaScript’s var, but the two are very different.

In this video, we’ll cover:

What is var in Java?

Difference between Java var vs JavaScript var

How compiler inference works (compile-time, not runtime)

Real-world use cases with generics, loops, and streams

Why var makes code cleaner but still strongly typed

Can you use var with null?

Is var a keyword in Java? Or a reserved type name?

🔑 Key Takeaways

var in Java = compile-time type inference
Type is fixed and cannot change dynamically
Works only for local variables (methods, constructors, blocks)
Great for generics and stream pipelines

Java remains statically typed, unlike JavaScript

Perfect For:

Java beginners learning modern features
Developers preparing for Java interviews
Anyone migrating to Java 10+
Those confused between Java var vs JavaScript var
for java interview prep
