Use the static fields and constructors of the class to implement the creation of the object of the class with a Java program

First, the experimental requirements

using the class's static fields and constructors, we can track the number of objects created by a class. Write a class that can query it at any time " How many objects have you created?" ".

Second, design ideas

1, create a class Find;

2, define a static integer variable i, so that its record creation of the number of objects;

3, define a function getnum () in the program, so that it returns the measurement value i;

4. Number of output object creation.

Third, the process flow chart

Iv. Source Code

public class Find

{

static int i;

Public Find ()

{

i++; Every object that creates a class I plus 1

}

static int Getnum ()

{

return i;

}

public static void Main (string[] args)

{

Find F1 = new Find ();

Find F2 = new Find ();

Find F3 = new Find ();

Find F4 = new Find ();

Find F5 = new Find ();

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

}

}

V. Results

Use the static fields and constructors of the class to implement the creation of the object of the class with a Java program
