In this tutorials will teach you @AllArgsConstructor and @NoArgsConstructor @Data annotations.what is the purpose we use this annotations is if we have a class it has Argument Constructor and No Argument Constructor and Getter and Setters and String Method. instead of implementing all of these.
i have attached two examples
Example 1
this example we implemented the Argument Constructor and No Argument Constructor and Getter and Setters and String Method.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 | public class EmployeeUpdateRequestDTO { private int employeeId; private String employeeName; private String employeeAddress; private double employeeSalary; private ArrayList contactNumbers; private String nic; private boolean activeState; public EmployeeUpdateRequestDTO(int employeeId, String employeeName, String employeeAddress, double employeeSalary, ArrayList contactNumbers, String nic, boolean activeState) { this.employeeId = employeeId; this.employeeName = employeeName; this.employeeAddress = employeeAddress; this.employeeSalary = employeeSalary; this.contactNumbers = contactNumbers; this.nic = nic; this.activeState = activeState; } public EmployeeUpdateRequestDTO() { } public int getEmployeeId() { return employeeId; } public void setEmployeeId(int employeeId) { this.employeeId = employeeId; } public String getEmployeeName() { return employeeName; } public void setEmployeeName(String employeeName) { this.employeeName = employeeName; } public String getEmployeeAddress() { return employeeAddress; } public void setEmployeeAddress(String employeeAddress) { this.employeeAddress = employeeAddress; } public double getEmployeeSalary() { return employeeSalary; } public void setEmployeeSalary(double employeeSalary) { this.employeeSalary = employeeSalary; } public ArrayList getContactNumbers() { return contactNumbers; } public void setContactNumbers(ArrayList contactNumbers) { this.contactNumbers = contactNumbers; } public String getNic() { return nic; } public void setNic(String nic) { this.nic = nic; } public boolean isActiveState() { return activeState; } public void setActiveState(boolean activeState) { this.activeState = activeState; } @Override public String toString() { return "EmployeeUpdateRequestDTO{" + "employeeId=" + employeeId + ", employeeName='" + employeeName + '\'' + ", employeeAddress='" + employeeAddress + '\'' + ", employeeSalary=" + employeeSalary + ", contactNumbers=" + contactNumbers + ", nic='" + nic + '\'' + ", activeState=" + activeState + '}'; } |
Example 2
instead of implementing all of these just write these annotations. These annotations this can manage by all the works.
if you want add these annotations you have to add the maven lombok dependency.click here
to add these dependency on the pom.xml file.
@AllArgsConstructor and @NoArgsConstructor @Data annotations
1 2 3 4 5 6 7 8 9 10 11 12 13 | @AllArgsConstructor @NoArgsConstructor @Data public class EmployeeUpdateRequestDTO { private int employeeId; private String employeeName; private String employeeAddress; private double employeeSalary; private ArrayList contactNumbers; private String nic; private boolean activeState; } |
