Constructors in Java Explained

Java Constructors

Special methods initializing objects automatically.

Multiple Constructors

public class Student {
    String name;
    int age;
    
    // Default constructor
    public Student() {
        this.name = "Unknown";
        this.age = 0;
    }
    
    // Parameterized constructor
    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }
}

Key Points

• No return type, same name as class.
• Default constructor auto-generated if none exists.
• Constructor overloading provides flexibility.
• this() calls another constructor.
