Copy file to Server to Local
scp -P <port> <localfile path> <server user>@ip:<remote user home path>
ex: > scp -P 22 mq/target/test.jar drvijay@192.2.2.2:/home/drvijay
Connect server :
Steps 1:
Source
Person.java(list address)
Address.java(User.java)
public class Person implements Serializable
{
private String firstName;
private String lastName;
private int age;
private List <Address> addressList;
}
public class Address implements Serializable
{
private int id;
private String address1;
private String address2;
private String city;
private String state;
private String country;
private String pincode;
private String contactNumber;
private String email;
private User user;
}
Target
PersonDTO.java (list addressDTO)
AddressDTO.java (User.java)
public class PersonDTO implements Serializable
{
private String firstName;
private int age;
private String lastName;
private List <AddressDTO> addressList;
}
public class AddressDTO implements Serializable
{
private int id;
private String address1;
private String address2;
private String city;
private String state;
private String country;
private String pincode;
private String contactNumber;
private String email;
private User user;
}
Step 2: Sample java class
package com.drvijay;
import java.lang.reflect.Field;
import java.lang.reflect.Modifier;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashMap;
import java.util.List;
import org.apache.commons.lang3.RandomStringUtils;
import com.product.base.utils.ObjectUtils;
import com.product.base.utils.ProductConstants;

@SuppressWarnings ( "unused" )
public class UtilHelper
{
private static final long serialVersionUID = 1L;
public static void copy ( Object source, Object target ) throws IllegalArgumentException, IllegalAccessException
{
Class <?> sourceClass = source.getClass ();
Class <?> targetClass = target.getClass ();
Field [] sourceFields = sourceClass.getDeclaredFields ();
Field [] targetFields = targetClass.getDeclaredFields ();
for ( Field sourceField : sourceFields )
{
for ( Field targetField : targetFields )
{
// If the source and target fields have the same name and type
if ( sourceField.getName ().equals ( targetField.getName () ) && sourceField.getType ().equals ( targetField.getType () ) )
{
// Make the source and target field accessible
sourceField.setAccessible ( true );
targetField.setAccessible ( true );
// Copy the value from the source field to the target field
targetField.set ( target, sourceField.get ( source ) );
// Stop looping through the target fields
break;
}
}
}
}
public static void main ( String [] args ) throws Exception
{
// Create a source object
Person sourcePerson = new Person ();
sourcePerson.setFirstName ( "vijay" );
sourcePerson.setLastName ( "kumar" );
sourcePerson.setAge ( 30 );
User u = new User ();
u.setUA ( "ua" );
u.setUB ( "ub" );
List<Address> aList = new ArrayList();
Address address = new Address ();
address.setAddress1 ( "add 1" );
address.setAddress2 ( "add 2" );
address.setPincode ( "54534" );
address.setUser ( u );
aList.add ( address );
address = new Address ();
address.setAddress1 ( "add 11" );
address.setAddress2 ( "add 22" );
address.setPincode ( "545341" );
aList.add ( address );
sourcePerson.setAddressList ( aList );
// Create a target object with similar properties
PersonDTO targetPersonDTO = new PersonDTO ();
// Copy the properties from the source object to the target object
UtilHelper.copy ( sourcePerson, targetPersonDTO );
// Print the values of the target object
System.out.println ( targetPersonDTO.getFirstName () );
System.out.println ( targetPersonDTO.getAge () );
System.out.println ( sourcePerson.toString () );
System.out.println ( targetPersonDTO.toString () );
System.out.println ( targetPersonDTO.getAddressList ().toString () );
}
}
Output

Extract the downloaded file. Copy the folder to ~/.local/share/gnome-shell/extensions directory. Go to your Home directory and press Crl+H to show hidden folders. Locate .local folder here and from there, you can find your path till extensions directory.
Once you have the files copied in the correct directory, go inside it and open metadata.json file. Look for the value of uuid.
Make sure that the name of the extension’s folder is same as the value of uuid in the metadata.json file. If not, rename the directory to the value of this uuid.
Almost there! Now restart GNOME Shell. Press Alt+F2 and enter r to restart GNOME Shell.
Restart GNOME Tweaks tool as well. You should see the manually installed GNOME extension in the Tweak tool now. You can configure or enable the newly installed extension here.
And that’s all you need to know about installing GNOME Shell Extensions.
It is totally understandable that you might want to remove an installed GNOME Shell Extension.
If you installed it via a web browser, you can go to the installed extensions section on GNOME website and remove it from there (as shown in an earlier picture).
If you installed it manually, you can remove it by deleting the extension files from ~/.local/share/gnome-shell/extensions directory.
