object - Updating elements in an ArrayList in Java? -

i have following class:

public class profile{     string name, age, location; } 

say have following code:

arraylist<profile> profiles = somepopulatedarraylist; profile profile = profiles.get(1); profile.name = "new name here"; 

my question when have above, .name of object in arraylist getting updated, or creating new object here , changing .name of object while profile object stored in arraylist still has old name?

i'm trying edit properties of objects in arraylist , i'm wondering if above approach correct or not?

no new object created, modifying existing value.

in fact not practice,you should allow access class variables directly, make them private , provide setter/getter methods same.

public class profile {     private string name, age, location;      public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }      public string getage() {         return age;     }      public void setage(string age) {         this.age = age;     }      public string getlocation() {         return location;     }      public void setlocation(string location) {         this.location = location;     }  }
