⚙️ What is a Static Block in Java?
A static block in Java is a block of code enclosed in a static {} block that is executed only once, when the class is loaded into memory by the JVM. It is used to initialize static variables or perform operations that need to be executed before any object is created or before the main() method runs.
🧱 Syntax:
java
Copy
Edit
class Example {
static {
System.out.println("Static block executed.");
}
public static void main(String[] args) {
System.out.println("Main method executed.");
}
}
🕒 When Is It Executed?
The static block is executed exactly once, when the class is first loaded.
It runs before constructors and even before the main() method.
If multiple static blocks exist, they are executed in the order they appear.
📌 Use Cases:
Initializing static variables (e.g., constants or configuration)
Loading native libraries
Logging or preloading resources
Setting up initial class-level conditions
⚠️ Key Points:
Static blocks cannot access non-static members directly.
You don’t need to create an object for a static block to run.
Good for logic that must run once per class.
✅ Example:
java
Copy
Edit
class Demo {
static int data;
static {
data = 100;
System.out.println("Static block: data initialized");
}
}
In this example, data is initialized when the class is loaded.
