Can a class in Java only implement one interface?

A class in Java can implement multiple interfaces. Syntax for implementing multiple interfaces: class MyClass implements Interface1, Interface2, Interface3 { // ...}. Advantages: 1. Allows multiple functions; 2. Improves reusability; 3. Adapts to different needs. Example: interface Animal {void makeSound();} interface Mammal {void giveBirth();} class Cat implements Animal, Mammal {..

Can a class in Java implement only one interface?

No, a class in Java can implement multiple interfaces.

Implementing multiple interfaces

Java allows a class to implement multiple interfaces by using the following syntax:

<code class="java">class MyClass implements Interface1, Interface2, Interface3 {
    // ...
}</code>

In the above example , MyClass class implements three interfaces: Interface1, Interface2 and Interface3. This means that MyClass must implement all methods defined in these three interfaces.

Interface inheritance

Interfaces can inherit other interfaces. This means that one interface can have all the methods of another interface. For example, if Interface2 inherits Interface1, then the MyClass class only needs to implement the Interface2 method, and it will automatically implement All methods of Interface1.

Advantages

Implementing multiple interfaces provides the following advantages:

• Allows a class to have multiple functions from different interfaces.
• Improves code reusability and flexibility.
• Allows classes to adapt more easily to different needs and requirements.

Example

The following is a simple example of implementing multiple interfaces:

<code class="java">interface Animal {
    void makeSound();
}

interface Mammal {
    void giveBirth();
}

class Cat implements Animal, Mammal {
    @Override
    public void makeSound() {
        System.out.println("Meow!");
    }

    @Override
    public void giveBirth() {
        System.out.println("Giving birth...");
    }
}</code>

In this example, Cat# The ## class implements the Animal and Mammal interfaces. It can both make sounds and give birth to babies.
