What is the difference between a method and a constructor?

Method - a block of code that performs a specific task and can be called by name. It can return a value and accept parameters.

Constructor - a special method used to initialize objects of a class. It has the same name as the class, does not have a return type (not even void), and is called when creating an object using the new operator.

Criterion	Method	Constructor
Purpose	Performs actions	Initializes an object
Name	Arbitrary (according to naming rules)	Same as the class name
Return type	Can be any (including void)	Has no return type (not even void)
Call	Explicitly called by object name	Called automatically when creating an object
Inheritance	Can be inherited	Cannot be inherited
Abstractness	Can be abstract	Cannot be abstract

public class Example {

    private int value;

    // This is a constructor
    public Example(int value) {
        this.value = value; // Initialize class field
    }

    // This is a method
    public int getValue() {
        return value; // Return the field value
    }

    // This is another method
    public void setValue(int value) {
        this.value = value; // Change the field value
    }

    /* Another method */
    public static void main(String[] args) {
        Example obj = new Example(10); // Call constructor to create object
        System.out.println(obj.getValue()); // Call getValue() method
        obj.setValue(20); // Call setValue() method
        System.out.println(obj.getValue());
    }
}
