Storing Java Object In ArrayList

Storing Java Object In ArrayList

Now we will make a arraylist of java object. Many times our java application needs to store java object in arraylist . For this firstly we make a arraylist of User type(In this program). Then store object of user in this.

import java.util.ArrayList;
import java.util.Iterator;

public class ArrayListOfObject {

public static void main(String[] args) {
ArrayList<User> arr = new ArrayList<User>();
arr.add(new User(“Raja”, 20));
arr.add(new User(“Ariseter”, 5));
arr.add(new User(“ManSingh”,15));

Iterator<User> itr = arr.iterator();
while (itr.hasNext()) {
User user = itr.next();
System.out.println(“Name=”+user.getName()+” Age=”+user.getAge());
}

}

}

class User{
private String name;
private int age;

public User(String name, int age) {
super();
this.name = name;
this.age = age;
}

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}

}

Output:

Name=Raja Age=20

Name=Ariseter Age=5

Name=ManSingh Age=15
