Java ArrayList…

The following code demonstrates how to use a Java ArrayList<T>… its a very simple demo.

 

import java.util.ArrayList;

public class MyMolecules {

public static void main(String[] args) {

ArrayList<Molecule> myMolecules = new ArrayList<Molecule>();

Molecule m1 = new Molecule(“First”);

Molecule m2 = new Molecule(“Second”);

Molecule m3 = new Molecule(“Third”);

Molecule m4 = new Molecule(“Fourth”);

myMolecules.add(m1);

myMolecules.add(m2);

myMolecules.add(m3);

myMolecules.add(m4);

for (Molecule item : myMolecules) {

System.out.println(item.getName());

}

    }

};

public class Molecule {

private String name;

public String getName() {

    return name;

}

public void setName(String name) {

    this.name = name;

}

public Molecule(String name){

this.name = name;

    }

}
