☕️ Java Interview Questions with Answers (Part 3)
1️⃣1️⃣ What is Method Overloading in Java?
👉 Method Overloading means having multiple methods with the same name but different parameter lists in the same class.
💡 Overloading is resolved at compile time.
1️⃣2️⃣ What is Method Overriding in Java?
👉 Method Overriding occurs when a subclass provides its own implementation of an inherited method.
💡 Overriding is associated with runtime polymorphism.
1️⃣3️⃣ What is the

1️⃣1️⃣ What is Method Overloading in Java?
👉 Method Overloading means having multiple methods with the same name but different parameter lists in the same class.
class Calculator {
int add(int a, int b) {
return a + b;
}
double add(double a, double b) {
return a + b;
}
}💡 Overloading is resolved at compile time.
1️⃣2️⃣ What is Method Overriding in Java?
👉 Method Overriding occurs when a subclass provides its own implementation of an inherited method.
class Animal {
void sound() {
System.out.println("Animal sound");
}
}
class Dog extends Animal {
@Override
void sound() {
System.out.println("Bark");
}
}💡 Overriding is associated with runtime polymorphism.
1️⃣3️⃣ What is the
this Keyword in Java?👉
this refers to the current object.It is commonly used to:
🔹 Access current object's fields
🔹 Call current class methods
🔹 Invoke another constructor
Example:
class Student {
String name;
Student(String name) {
this.name = name;
}
}1️⃣4️⃣ What is the
super Keyword in Java?👉
super refers to the immediate parent class.It can be used to:
🔹 Access parent fields
🔹 Call parent methods
🔹 Call the parent constructor
Example:
class Animal {
String name = "Animal";
}
class Dog extends Animal {
String name = "Dog";
void display() {
System.out.println(super.name);
}
}📌 Output:
Animal
1️⃣5️⃣ What is the
static Keyword in Java?👉
static indicates that a member belongs to the class rather than a particular object.Example:
class Counter {
static int count = 0;
Counter() {
count++;
}
}
public class Main {
public static void main(String[] args) {
new Counter();
new Counter();
System.out.println(Counter.count);
}
}📌 Output:
2
💡 A static field is shared among instances of the class.
