Java编写员工薪资表
1、首先打国夏五开eclipse
2、新建一个java项目，名字随意起
3、名字起好后，点击完成
4、右键点帽强击项目名称，新建，类
5、类的名字叫TextInterface
包的名字叫 com.zf.s2
点击完成
6、首先创建一个员工类
class Employee {// 员工类
private String name;// 员工名称
private String gender;// 员工性别
private int age;// 员工年龄
private int salary;// 员工薪资
public Employee(String name, String gender, int age, int salary) {
super();
this.name = name;
this.gender = gender;
this.age = age;
this.salary = salary;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getSalary() {
return salary;
}
public void setSalary(int salary) {
this.salary = salary;
}
}
7、定义输出二维表的接口
interface PersonForm {
public int getFormCol();// 获得表格的列数
public int getFormRow();// 获得表格的行数
public String getValue(int row, int col);// 获得指定的某行某列的值
public String getColName(int col);// 获得指定的列名
}
针颂
8、class FormA implements PersonForm {// 定义一个类实现接口
String[][] data;// 定义一个二维数组
public FormA(String[][] data) {// 带参数的构造方法
this.data = data;
}
public String getColName(int col) {// 获得指定的列名
return data[0][col];
}
public int getFormCol() {// 获得表格的列数
return data[0].length;
}
public int getFormRow() {// 获得表格的行数
return data.length - 1;
}
public String getValue(int row, int col) {// 获得指定的某行某列的值
return data[row + 1][col];
}
}
9、class FormB implements PersonForm {// 定义一个类实现接口
private Employee[] data;
public FormB(Employee[] data) {// 带参数的构造方法
this.data = data;
}
public String getColName(int col) {
switch (col) {
case 0:
return "姓名\t|";
case 1:
return "性别\t|";
case 2:
return "年龄\t|";
case 3:
return "工资\t|";
default:
return null;
}
}
public int getFormCol() {
return 4;
}
public int getFormRow() {
return data.length;
}
public String getValue(int row, int col) {
switch (col) {
case 0:
return data[row].getName();
case 1:
return data[row].getGender();
case 2:
return data[row].getAge() + "";
case 3:
return data[row].getSalary() + "";
default:
return null;
}
}
}
10、class Table {// 表格类
private PersonForm form;
public Table(PersonForm form) {// 带参数的构造方法
this.form = form;
}
public void display() {// 显示格式和取值
for (int i = 0; i < form.getFormCol(); i++) {// 循环显示列名
System.out.print(form.getColName(i));
}
System.out.println();
System.out.println("---------------------------------");
for (int i = 0; i < form.getFormRow(); i++) {// 循环显示行信息
for (int j = 0; j < form.getFormCol(); j++) {// 循环显示列信息
System.out.print(form.getValue(i, j) + "\t|");
}
System.out.println();
}
}
}
11、public class TextInterface {// 操作接口的类
public static void main(String[] args) {// java程序主入口处
String[][] str = new String[][] {//创建二维数组存储数据
{ "name\t|", "gender\t|", "age\t|", "salary\t|" },
{ "Tom", "male", "20", "2000" },
{ "Lingda", "female", "21", "2100" },
{ "Susan", "female", "22", "2200" },
{ "Ansen", "female", "24", "2500" } };
PersonForm form=new FormA(str);//接口变量引用类对象
Table table1=new Table(form);//创建表格实例
table1.display();// 显示员工薪资信息
System.out.println("^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^");
Employee em1 = new Employee("汤姆", "男", 20, 2000);// 创建员工对象用一维数组存储
Employee em2 = new Employee("玲达", "女", 21, 2100);
Employee em3 = new Employee("苏萨", "女", 22, 2200);
Employee em4 = new Employee("爱瑞卡", "男", 23, 2300);
Employee em5 = new Employee("安臣", "女", 24, 2500);
Employee[] data = { em1, em2, em3, em4, em5 };// 创建员工数组
PersonForm form1 = new FormB(data);//接口变量引用类对象
Table table2 = new Table(form1);// 创建表格实例
table2.display();// 显示员工薪资信息
}
}
