Constructor $(3$ Parameters$)$:

The constructor should accept the item's name, cost, and price as arguments and assign

these values to the object's corresponding instance variables.

The constructor should also initialize weight to $1\mathrm{.}0$ kg and taxable to true by default.

Note: Ensure that the constructor does not allow negative values for the price or cost$.$ If

negative values are passed, set them to $0$ and print an appropriate error message.

Add Accessor and Mutator Methods:

Provide getter and setter methods for all instance variables.

Ensure that the setter methods for price, cost, and weight do not allow negative values.

Add the increaseCost $()$ Method:

This method should increase the cost price of the item by $5\%$ each time it is called. This is a

void method as it modifies the current state of the object.

Add the profit$()$ Method:

This method should accept no parameters and return the profit of the item, which is calculated

as the selling price minus the cost price. Note: Ignore taxes in this calculation.

Add the toString $()$ Method:

This method should display the contents of the item's instance variables in a well$-$formatted

string. For example:

"Item: Desk Chair, Price: $30\mathrm{.}0$ AED, Cost: $55\mathrm{.}0$ AED, Weight: $3\mathrm{.}0$ kg $,$ Taxable: true"
