法学基于员工薪资的Go语言筛选程序
在使用Go语言处理数据集时，了解过滤器非常重要，因为在某些情况下，您可能需要分析数据以获得自定义结果。在本文中，我们将使用传统的循环方法、函数方法以及使用goroutine的方法来创建基于员工薪资的员工列表过滤器。
示例 1
在下面的代码中，“FilterEmployeeBySallary()”根据薪资范围筛选员工列表，并返回落在该薪资范围内的员工列表。
package main
import "fmt"
type Employee struct {
Name string
Salary int
}
func FilterEmployeesBySalary(employees []Employee, minSalary, maxSalary int) []Employee {
var filteredEmployees []Employee
for _, employee := range employees {
if employee.Salary >= minSalary && employee.Salary <= maxSalary {
filteredEmployees = append(filteredEmployees, employee)
}
}
return filteredEmployees
}
func main() {
employees := []Employee{
{Name: "Aman", Salary: 50000},
{Name: "Nitin", Salary: 70000},
{Name: "Akhi", Salary: 40000},
{Name: "Akshay", Salary: 60000},
}
filtered := FilterEmployeesBySalary(employees, 45000, 65000)
fmt.Println("Filtered Employees:", filtered)
}
输出
Filtered Employees: [{Aman 50000} {Akshay 60000}]
示例 2
在下面的代码中，“filterEmployees”函数根据给定的过滤器筛选员工列表，而“sallaryFilter()”函数返回一个用于根据薪资筛选员工的过滤器函数。
package main
import "fmt"
type Employee struct {
Name string
Salary int
}
type FilterFunc func(Employee) bool
func FilterEmployees(employees []Employee, filterFunc FilterFunc) []Employee {
var filteredEmployees []Employee
for _, employee := range employees {
if filterFunc(employee) {
filteredEmployees = append(filteredEmployees, employee)
}
}
return filteredEmployees
}
func SalaryFilter(minSalary, maxSalary int) FilterFunc {
return func(employee Employee) bool {
return employee.Salary >= minSalary && employee.Salary <= maxSalary
}
}
func main() {
employees := []Employee{
{Name: "Sam", Salary: 50000},
{Name: "Akhil", Salary: 70000},
{Name: "Akshay", Salary: 40000},
{Name: "Summer", Salary: 80000},
}
salaryFilter := SalaryFilter(45000, 85000)
filtered := FilterEmployees(employees, salaryFilter)
fmt.Println("Filtered Employees:", filtered)
}
输出
Filtered Employees: [{Sam 50000} {Akhil 70000} {Summer 80000}]
示例 3
下面的代码为每个员工创建一个goroutine，以异步方式根据给定的薪资筛选他们，并将筛选后的员工通过通道发送，主函数接收筛选后的员工并返回最终结果。
package main
import (
"fmt"
"time"
)
type Employee struct {
Name string
Salary int
}
func FilterEmployeesConcurrently(employees []Employee, minSalary, maxSalary int) []Employee {
var filteredEmployees []Employee
employeeChannel := make(chan Employee)
for _, employee := range employees {
go func(e Employee) {
if e.Salary >= minSalary && e.Salary <= maxSalary {
employeeChannel <- e
}
}(employee)
}
// Collect filtered employees from the channel
go func() {
for employee := range employeeChannel {
filteredEmployees = append(filteredEmployees, employee)
}
}()
time.Sleep(time.Millisecond)
return filteredEmployees
}
func main() {
employees := []Employee{
{Name: "Arya", Salary: 5000},
{Name: "Sansa", Salary: 7000},
{Name: "Rob", Salary: 4000},
{Name: "John", Salary: 6000},
}
filtered := FilterEmployeesConcurrently(employees, 4500, 6500)
fmt.Println("Filtered Employees:", filtered)
}
输出
Filtered Employees: [{Arya 5000} {John 6000}]
结论
在本文中，我们讨论了如何在Go语言中根据员工薪资创建员工过滤器。我们探索了三种不同的方法：使用goroutine和通道、传统的循环方法和函数式方法。
