java实现简陋员工信息管理

 刚开始学java，只能做到这个水平了。

以下为源代码

MAIN(主程序)

package StaMa;

public class MAIN {

	public static void main(String[] args) {

		STAMA sta1 = new STAMA("张铭", "S001", "男", 29);
		STAMA sta2 = new STAMA("李艾爱", "S002", "女", 21);
		STAMA sta3 = new STAMA("孙超", "S003", "男", 29);
		STAMA sta4 = new STAMA("张美美", "S004", "女", 26);
		STAMA sta5 = new STAMA("蓝迪", "S005", "男", 37);
		STAMA sta6 = new STAMA("米莉", "S006", "女", 24);

		DEMA depart1 = new DEMA("D001", "人事部");
		DEMA depart2 = new DEMA("D002", "市场部");

		POST post1 = new POST("经理", "P001");
		POST post2 = new POST("助理", "P002");
		POST post3 = new POST("职员", "P003");

		depart1.addStaff(sta1);
		depart1.addStaff(sta2);
		depart1.addStaff(sta3);
		depart2.addStaff(sta4);
		depart2.addStaff(sta5);
		depart2.addStaff(sta6);

		post1.addPost(sta1);
		post1.addPost(sta5);
		post2.addPost(sta2);
		post3.addPost(sta3);
		post3.addPost(sta4);
		post3.addPost(sta6);

		System.out.println(sta1.introduction());
		System.out.println("==========================");
		System.out.println(sta2.introduction());
		System.out.println("==========================");
		System.out.println(sta3.introduction());
		System.out.println("==========================");
		System.out.println(sta4.introduction());
		System.out.println("==========================");
		System.out.println(sta5.introduction());
		System.out.println("==========================");
		System.out.println(sta6.introduction());
		System.out.println("==========================");

		System.out.println(depart1.getDepartmentName() + "总共有" + depart1.getStaffCount() + "名员工");
		System.out.println(depart2.getDepartmentName() + "总共有" + depart2.getStaffCount() + "名员工");
	}

}

STAMA(staff management)(员工管理)

package StaMa;


public class STAMA {
	
	private String staffName;
	private String staffNo;
	private String staffSex;
	private DEMA myDepartment;
	private int staffAge;

	public STAMA() {

	}

	}

	public POST getMyPost() {

	}

	public void setMyPost(POST myPost) {

	}

	
	public String introduction() {
		String str = "姓名：" + this.getStaffName() + "n工号：" + this.getStaffNo() + "n性别：" +this.getStaffSex() + "n年龄："

	}
}

DEMA(department management)(部门管理)

package StaMa;

public class DEMA {

	}

	public void setDepartmentName(String departmentName) {
		this.departmentName = departmentName;
	}

	public STAMA[] getStaff() {
		if (this.staff == null)//防止出现空指针错误
			this.staff = new STAMA[10];
		return staff;
	}

	public void setStaff(STAMA[] staff) {
		this.staff = staff;
	}

	public int getStaffCount() {

			if (this.getStaff()[i] == null) {
				sta.setMyDepartment(this);
				this.getStaff()[i] = sta;
				this.setStaffCount(i + 1);
				return;
			}
	}
}

POST(职位）

package StaMa;

public class POST {

	private String postNo;
	private String postName;

	public POST() {

	}

	public POST(String postName, String postNo) {
		this.setPostName(postName);

	}

	public String getPostNo() {

	}

	public void setPostNo(String postNo) {
