Create the class Suitcase. Suitcase has things and a maximum weight limit, which defines the greatest total allowed weight of the things contained within the Suitcase object.

Add the following methods to your class:

• A constructor, which is given a maximum weight limit


• public void addThing(Thing thing), which adds the thing in the parameter to your suitcase. The method does not return any value.


• public String toString(), which returns a string in the form "x things (y kg)"

The things are saved into an ArrayList object:

ArrayList things =new ArrayList();

The class Suitcase has to make sure the thing's weight does not cause the total weight to exceed the maximum weight limit. The method addThing should not add a new thing if the total weight happens to exceed the maximum weight limit.

Below, you find an example of how the class can be used:

publicclass Main {

publicstatic voidmain(String[] args) {

        Thing book =newThing("Happiness in three steps", 2);

        Thing mobile =newThing("Nokia 3210", 1);

        Thing brick =newThing("Brick", 4);

        Suitcase suitcase =newSuitcase(5);

        System.out.println(suitcase);

        suitcase.addThing(book);

        System.out.println(suitcase);

        suitcase.addThing(mobile);

        System.out.println(suitcase);

        suitcase.addThing(brick);

        System.out.println(suitcase);

    }

}

The program output should look like the following:

0 things (0 kg)

1 things (2 kg)

2 things (3 kg)

2 things (3 kg)

This is class Thing

public class Thing {

privateStringname;

privateintweight;

publicThing(Stringname,intweight){

this.name=name;

this.weight=weight;

}

publicStringgetName(){

// returns the thing's name

returnthis.name;

}

publicintgetWeight(){

// returns the thing's weight

returnthis.weight;

}

publicStringtoString(){

returnthis.name+" ("+this.weight+" kg)";

}

}
