Problem statement

In this program, we will create a Sample class with a method. Then we will create an array of objects.

Java program to create an array of objects

The source code to create an array of objects is given below. The given program is compiled and executed successfully.

// Java program to create an array 
// of objects

class Sample {
  void sayHello() {
    System.out.println("Hello World");
  }
}

class Main {
  public static void main(String args[]) {
    Sample[] arrObj = new Sample[3];

    arrObj[0] = new Sample();
    arrObj[1] = new Sample();
    arrObj[2] = new Sample();

    arrObj[0].sayHello();
    arrObj[1].sayHello();
    arrObj[2].sayHello();
  }
}

Output

Hello World
Hello World
Hello World

Explanation

In the above program, we created a Sample class and public class Main. The Sample class contains a method sayHello(). The sayHello() method prints the "Hello World" message.

The Main class contains a static method main(). The main() is an entry point for the program. Here, we created an array of 3 objects. Then we called the sayHello() method of each object and printed the "Hello World" message.
