What is the difference between a constructor and a method in Java?

A constructor is a special type of method that is used to create an instance of a class. It is called when an object of a class is created and has the same name as the class. A constructor does not have a return type and is used to initialize the state of an object.

Example:

public class Car {
private String make;
private String model;

// Constructor
public Car(String make, String model) {
this.make = make;
this.model = model;
}
}

A method is an ordinary subroutine that is used to perform a specific task. It is declared with a return type and a name, and can take arguments. It is called on an instance of a class and can return a value.

Example:

public class Car {
private String make;
private String model;

// Method
public String getMake() {
return make;
}
}

A constructor is a special method that is used to create and initialize an object. It is called when an object is created and is usually used to set up the initial state of the object. For example, the constructor of a class might set the default values for the properties of the object.

A method is a subroutine or function associated with a class. It is used to perform an action or to retrieve data. For example, a method of a class might be used to calculate the area of a rectangle or to retrieve a specific record from a database.

A constructor is a special type of method that is used to create an instance of an object. It is invoked when an instance of the object is created and it is used to set up the initial state of the object.

A method is a block of code that performs a specific task and is associated with an object. It is invoked by calling the method on the object.

Example:

Constructor:

public class Car {
private String make;
private String model;

public Car(String make, String model) {
this.make = make;
this.model = model;
}
}

Method:

public class Car {
private String make;
private String model;

public void setMake(String make) {
this.make = make;
}

public void setModel(String model) {
this.model = model;
}
}
