Define a class named Employee with the following fields: empID , empName , deptID , bloodGroup , salary. Define following methods : setEmployeeDetails( ), printEmployeeDetails( ) Prompt the user to enter values.

Objective

Define an Employee class with state (fields) and behavior (methods) to set and print details.

Algorithm / Approach

  1. Create an Employee class with fields: empID, empName, deptID, bloodGroup, and salary.
  2. Define a setEmployeeDetail() method that uses a Scanner to read input from the user and assign them to the fields.
  3. Define a printEmployeeDetails() method that prints out all the fields in a formatted way.
  4. In the main method, create an Employee object.
  5. Call the setEmployeeDetail() method on the object.
  6. Call the printEmployeeDetails() method on the object.
Employee.java 
import java.util.Scanner;
class Employee {
 int empID,deptID,salary;
 String empName,bloodGroup;
 void setEmployeeDetail() {
  Scanner s=new Scanner(System.in);
  System.out.print("Enter empId: ");
  empID=Integer.parseInt(s.nextLine());
  System.out.print("Enter Name: ");
  empName = s.nextLine();
  System.out.print("Enter Dept. Id: ");
  deptID=Integer.parseInt(s.nextLine());
  System.out.print("Enter Blood Group: ");
  bloodGroup= s.nextLine();
  System.out.print("Enter Salary: ");
  salary=Integer.parseInt(s.nextLine());
 }
 void printEmployeeDetails() {
  System.out.println("EMP. ID - "+empID+
          "\nEMP NAME - "+empName+
           "\nDEPT ID - "+deptID+
          "\nBLOOD GROUP - "+bloodGroup+
          "\nSALARY - "+salary);
 }
 public static void main(String[] a)
 {
  Employee e = new Employee();
  e.setEmployeeDetail();
  e.printEmployeeDetails();
 }
}

Expected Output

Enter empId: 12
Enter Name: Alok
Enter Dept. Id: 5
Enter Blood Group: A
Enter Salary: 30000
EMP. ID - 12
EMP NAME - Alok
DEPT ID - 5
BLOOD GROUP - A
SALARY - 30000

Explanation of the Program

  • This program demonstrates how objects encapsulate data (fields) and operations (methods) together.
  • The fields define the properties every Employee will have. The methods define what an Employee can do.
  • Because the fields are declared at the class level (instance variables), they are accessible by both the setEmployeeDetail and printEmployeeDetails methods.
  • Notice the use of Integer.parseInt(s.nextLine()). This prevents the common scanner bug where reading an integer leaves a newline character in the buffer, which would accidentally skip the next String input.

Complexity

Time Complexity O(1)
Space Complexity O(1)

Common Mistakes

  • Using nextInt() followed directly by nextLine() without clearing the buffer, causing the String input to be skipped.
