Java Program to Count Number of Objects Created for Class

This is a Java Program to Find Out the Number of Objects Created of a Class.

Whenever an object is made of a class, its constructor is invoked. Whenever the constructor runs we increment the counter value. Hence number of objects created of a class equals to the counter value.

Here is the source code of the Java Program to Find Out the Number of Objects Created of a Class. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
public class Number_Objects 
```
```
{
```
```
    static int count=0;
```
```
    Number_Objects()
```
```
    {
```
```
        count++;
```
```
    }
```

    public static void main(String[] args)

```
    {
```

        Number_Objects obj1 = new Number_Objects();

        Number_Objects obj2 = new Number_Objects();

        Number_Objects obj3 = new Number_Objects();

        Number_Objects obj4 = new Number_Objects();

        System.out.println("Number of objects created:"+count);

```
    }
```
```
}
```

Output:

$ javac Number_Objects.java
$ java Number_Objects
 
Number of objects created:4
