Java-ArrayList遍历的实例-员工工资表

ArrayList遍历实例-员工工资表:

示例代码如下:

员工信息操作类
import com.sun.prism.impl.shape.BasicRoundRectRep;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class EmployeeOperator {
    public static void main(String[] args) {
        List arrayList = new ArrayList();

        Employee zhangsan = new Employee(01,"张三","养猪部",2500.0);
        Employee lisi  =new Employee(02,"李四","掏粪部",3000);
        Employee wangwu = new Employee(03,"王五","大数据开发",26849.8);

        arrayList.add(zhangsan);
        arrayList.add(lisi);
        arrayList.add(wangwu);

        //1,雇员工资打印:
        System.out.println("本月员工名和工资: ");
        for(int i=0; i<arrayList.size(); i++){
            System.out.print(1+i+":"+ ((Employee)(arrayList.get(i))).getName());
            System.out.println(" 实发工资: "+ ((Employee)(arrayList.get(i))).getSalary());
        }
        //2-1, 遍历工资单(for循环)
        System.out.println("=====================");
        for(int j=0; j<arrayList.size(); j++){
            Employee s = (Employee)arrayList.get(j);
            System.out.print(""+s.getId()+" ");
            System.out.print(""+s.getName()+" ");
            System.out.print(""+s.getDepartment()+" ");
            System.out.println(""+s.getSalary());
        }
        ///2-2 遍历工资单(迭代器)
        System.out.println("=====================");
        Iterator iterator = arrayList.iterator();
        while(iterator.hasNext()){
            Employee s = (Employee) iterator.next();
            System.out.println(""+s.getId()+" "+s.getName() +" "+s.getDepartment()+" "+s.getSalary());
        }

        ///2-3 遍历工资单(foreach循环)
        System.out.println("=====================");
        for (Object object: arrayList) {
            Employee s =(Employee) object;
            System.out.println(""+s.getId()+" "+s.getName() +" "+s.getDepartment()+" "+s.getSalary());
        }
    }
}


///员工信息类
public class Employee {
    private int id;
    private String name;
    private String department;
    private double salary;

    public Employee(int id, String name, String department, double salary) {
        this.id = id;
        this.name = name;
        this.department = department;
        this.salary = salary;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDepartment() {
        return department;
    }

    public void setDepartment(String department) {
        this.department = department;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}
