In this tutorial we are going to see the use of clone method. In this example we are going to see how to use Clone method for BankCustomer.

public class CloneExample
  {
   public static void main(String[] args) {
    BankCustomer cus1 = new BankCustomer("Angel", "S");
    cus1.setSalary(90000.0);
    BankCustomer cus2 = (BankCustomer) cus1.clone();
    cus1.setLastName("Mathew");
    System.out.println(cus1);
    System.out.println(cus2);
  }
}

class BankCustomer {
  private String lastName;

  private String firstName;

  private Double salary;

  public BankCustomer(String lastName, String firstName) {
    this.lastName = lastName;
    this.firstName = firstName;
  }

  public String getLastName() {
    return this.lastName;
  }

  public void setLastName(String lastName) {

    this.lastName = lastName;
  }

  public String getFirstName() {
    return this.firstName;
  }

  public void setFirstName(String firstName) {
    this.firstName = firstName;
  }

  public Double getSalary() {
    return this.salary;
  }

  public void setSalary(Double salary) {
    this.salary = salary;
  }

  public Object clone() {
    BankCustomer cus;
    cus = new BankCustomer(this.lastName, this.firstName);
    cus.setSalary(this.salary);
    return cus;
  }

  public String toString() {
    return this.getClass().getName() + "[" + this.firstName + " " + this.lastName + ", "
        + this.salary + "]";
  }
}
