Group Name Change In ChatApps

Following Code will give u a small idea how that change takes place:

Code:


public class User {
    int i;
String name;
long mobile;
Group[] g=new Group[10];

User(){   //Default Constructor
i=0;
name="No Name";
mobile=0000000000;
}

User(String n,long m){   //Parameterized Constructor
i=0;
name=n;
mobile=m;
}

void createGroup(String gn)
{
   g[i++]=new Group(gn,this);
}
    
void changeGname(String gn,int i)
{
g[i].Gname=gn;
}
}

public class User {

    int i;

String name;

long mobile;

Group[] g=new Group[10];

User(){   //Default Constructor

i=0;

name="No Name";

mobile=0000000000;

}

User(String n,long m){   //Parameterized Constructor

i=0;

name=n;

mobile=m;

}

void createGroup(String gn)

{

   g[i++]=new Group(gn,this);

}

    

void changeGname(String gn,int i)

{

g[i].Gname=gn;

}

}

public class Main {

public static void main(String[] nt) {

User u1=new User("Dishant",9023074222l);

User u2=new User("Garvit",8284010455l);

User u3=new User("Piyush",9815445194l);

User u4=new User("Nikhil",9815215752l);

User u5=new User("Navneet",9888321686l);

u1.createGroup("Brothers");

User[] x={u2,u3,u4,u5};

u1.g[0].addUsers(x);

u4.g[0].showGname();

u1.changeGname("For", 0);

u2.g[0].showGname();

u2.changeGname("Life", 0);

u5.g[0].showGname();

u3.changeGname("Yeahhh", 0);

u1.g[0].showGname();

System.out.println("------------------");

u3.g[0].showUsers();

}

}
