Java employee details program

2025年4月14日 | 阅读 3 分钟

在Java中，搜索最多的程序是员工详情程序。员工是一个实体，可以拥有 id、姓名、部门等多个属性。为了创建一个 Java 员工详情程序，我们需要创建一个 Employee 类来表示员工实体，并创建员工的属性。

我们将创建 getter 和 setter 方法来获取和设置属性的值。在主类中，我们将创建 Employee 类的对象，并通过该对象访问 Employee 类的属性。

上述员工详情程序的代码非常容易理解。让我们来实现上面理论的实现代码。

EmployeeDetails.java

package JavaTpoint.JavaObjectToJSON;
//Creating Employee class
class EmployeeDetails {
	//Creating properties of Employee class
int emp_id, salary;
String name, address, department, email;

//Getter and setters for getting and setting properties
public int getEmp_id() {
	return emp_id;
}
public void setEmp_id(int emp_id) {
	this.emp_id = emp_id;
}
public int getSalary() {
	return salary;
}
public void setSalary(int salary) {
	this.salary = salary;
}
public String getName() {
	return name;
}
public void setName(String name) {
	this.name = name;
}
public String getAddress() {
	return address;
}
public void setAddress(String address) {
	this.address = address;
}
public String getDepartment() {
	return department;
}
public void setDepartment(String department) {
	this.department = department;
}
public String getEmail() {
	return email;
}
public void setEmail(String email) {
	this.email = email;
}

//Overriding toString() method
@Override
public String toString() {
	return "Employee [emp_id = " + emp_id + ", salary = " + salary + ", name = " + name + ", address = " + address
			+ ", department = " + department + ", email = " + email + "]";
	}
	
}
//Creating main class
public class Employee{
	//main() method start
	public static void main(String args[]) {
		
		//Creating object of EmployeeDetails class
		EmployeeDetails emp = new EmployeeDetails();
		//Setting values to the properties
		emp.setEmp_id(101);
		emp.setName("Emma Watson");
		emp.setDepartment("IT");
		emp.setSalary(15000);
		emp.setAddress("New Delhi");
		emp.setEmail("Emmawatson123@gmail.com");
		
		//Showing Employee details
		System.out.println(emp);
		
		//Getting salary using getter
		int sal = emp.getSalary();
		int increment = 0;
		//Incrementing salary based on condition
		if ((sal >=1000) && (sal <=1500))
		{
			//incrementing salary 2%
			increment += (sal * 2)/100;
			sal = sal+increment;
			
			emp.setSalary(sal);
			System.out.println("\n Salary is incremented \n");
			System.out.println(emp);
			
		}else if ((sal >=1500) && (sal <=20000)){
			//incrementing salary 5%
			increment += (sal * 5)/100;
			sal = sal+increment;
			
			emp.setSalary(sal);
			System.out.println("\n Salary is incremented \n");
			System.out.println(emp);
		}else {
			System.out.println("\n Salary is not incremented \n");
			System.out.println(emp);
		}		
	}
}

输出

Employee [emp_id = 101, salary = 15000, name = Emma Watson, address = New Delhi, department = IT, email = [email protected]]
 Salary is incremented 
Employee [emp_id = 101, salary = 15750, name = Emma Watson, address = New Delhi, department = IT, email = [email protected]]

在上面的程序中，我们为 Employee 类创建了有限的属性。您可以为 Employee 类创建任意数量的属性。在上面的代码中，我们不仅展示了员工详情，还通过 setter 访问了属性值。我们还可以根据条件更新属性值。
