## Do You Know What Overrides a Class’s Fields?

You’ve probably heard about inheritance in Java, but what about variable overriding?

In Java, when a local variable has the **same name** as a member variable (also known as a field) within the same scope, the local variable **overrides** the member variable. This means that within the specific block where the local variable is defined, the member variable’s value is effectively hidden.

**Here’s a simple example:**

“`java
class MyClass {
private int myVar = 10;

public void myMethod() {
int myVar = 20; // Local variable overrides the member variable
System.out.println(“Local myVar: ” + myVar); // Prints 20
System.out.println(“Member myVar: ” + this.myVar); // Prints 10 (still accessible through ‘this’)
}
}
“`

**Key points to remember:**

* **Scope is crucial:** Variable overriding happens only when local and member variables share the same name **within the same scope**.
* **’this’ keyword:** You can always access the member variable using the **`this` keyword** even if there is a local variable with the same name.
* **Overloading vs. overriding:** This concept is different from **method overloading**, where you have multiple methods with the same name but different parameters.

Let me know if you have any other questions about variable overriding in Java!
