Question in java language please answer ASAP

Question

interface IResit {

int number = 3;

char iChar = ‘#’;

}

interface IShape extends IResit {

public void drawShape ( );

// this method supposed to draw shapes with interface data as below:

/*

#

##

###

##

#

*/

}

interface IBilgi {

public void myShape(char myChar);

// this method supposed to draw shapes as below

// if , myChar = ‘*’

/*

#*

##

###*

##

#*

*/

} // note the “#” character comes from interface

// end of the interface….

/*

Write a class that implements interfaces given above. Your class should:

1. Have three constructors

Default constructor: it doesn’t take any parameter and necessary variables will be initialized by interface data.

Overloaded Constructor: takes one integer parameter, supposed to initialize the “number” variable

Overloaded Constructor: takes two parameters to initialize “number” and “iChar”variables

2. Create three different objects from three different constructors and test all methods given in interfaces

3. Your code should throw exceptions for invalid inputs

*/

// Note you must solve this question with using “while” loop only.

interface IResit

{

int number=3;

char iChar = '#';

public void drawShape();

}

interface IShape extends IResit

{

public void drawShape();

}

interface IBilgi

{

public void myShape(char myChar);

public void draw

}

class Shape implements IResit,IShape,IBilgi

{

protected int N;

protected char chChar;

Shape(int n)

{

chChar = iChar;

}

{

myShape(ch);

}

Shape(int n, char ch)

{

N = n; myShape(ch);

}

public int GetNum() { return(N); }

public char GetChar() { return(chChar); }

public void myShape(char myChar)

{
