法學基於員工薪資的Go語言篩選程式
在使用Go語言處理資料集時，瞭解過濾器非常重要，因為在某些情況下，您可能需要分析資料以獲得自定義結果。在本文中，我們將使用傳統的迴圈方法、函式方法以及使用goroutine的方法來建立基於員工薪資的員工列表過濾器。
示例 1
在下面的程式碼中，“FilterEmployeeBySallary()”根據薪資範圍篩選員工列表，並返回落在該薪資範圍內的員工列表。
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)
}
輸出
Filtered Employees: [{Aman 50000} {Akshay 60000}]
示例 2
在下面的程式碼中，“filterEmployees”函式根據給定的過濾器篩選員工列表，而“sallaryFilter()”函式返回一個用於根據薪資篩選員工的過濾器函式。
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)
}
輸出
Filtered Employees: [{Sam 50000} {Akhil 70000} {Summer 80000}]
示例 3
下面的程式碼為每個員工建立一個goroutine，以非同步方式根據給定的薪資篩選他們，並將篩選後的員工透過通道傳送，主函式接收篩選後的員工並返回最終結果。
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)
}
輸出
Filtered Employees: [{Arya 5000} {John 6000}]
結論
在本文中，我們討論瞭如何在Go語言中根據員工薪資建立員工過濾器。我們探索了三種不同的方法：使用goroutine和通道、傳統的迴圈方法和函式式方法。
