Members Java Program

Types of Data Members:
Java Class is a collection of data members and functions. Any java program may contain two types of data members. They are;
1. Instance or non-static data members
2. Static or class data members

The following table describes the difference between the two.


Types of Methods:
In java program generally we may define two types of methods apart from constructor. They are;
1. Instance or non –static methods
2. Static or class methods

The following table describes the difference between the two.

The following example named TestGVP.java demonstrates the use of different members of the java class.

// Java code to show structures and 

// members of Java Program

public class classMember

{

      

// Static member

static int staticNum = 0;

  

// Instance member 

int instanceNum;

  

/* below constructor increments the static 

number and initialize instance number */

public classMember(int i) //Constructor method

{

    instanceNum = i;

    staticNum++;

}

  

/* The show method display the value in the staticNum and instanceNum */

public void show() //instance method

{

    System.out.println("Value of Static Number is:" + staticNum + 

                        "\nValue of Instance number is:"+ instanceNum);

}

  

// To find cube

public static int cube() //Static method

{

    return staticNum * staticNum * staticNum;

}

  

// Driver code

public static void main(String args[])

{

    classMember gvp1 = new classMember(2);

    System.out.println("Value after gvp1 object creation: ");

    gvp1.show();

  

    classMember gvp2 = new classMember(4);

    System.out.println("Value after gvp2 object creation: ");

    gvp2.show();

      

    // static method can be accessed by class name

    int cub=classMember.cube();

    System.out.println("Cube of the Static number is: "+ cub);

}

}
