字符串函數在golang中的使用

package main

import (
    "fmt"
    "strings"
)

func main()  {
    //判斷父字符串是否包含子字符串，包含為真，否則為假
    fmt.Println("-------------------------------")
    fmt.Println("contains Function:", strings.Contains("Austrilia", "lia"))
    fmt.Println("contains Function:", strings.Contains("Austrilia", "mia"))

    //子字符串在父字符串中出現的次數
    fmt.Println("-------------------------------")
    fmt.Println("Count Function: ",strings.Count("Australia", "lia"))
    fmt.Println("Count Function: ",strings.Count("Australia", "A"))
    fmt.Println("Count Function: ",strings.Count("Australia", "Bu"))

    //判斷子字符串是否為父字符串的前綴
    fmt.Println("-------------------------------")
    fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Bu"))
    fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Aus"))

    ////判斷子字符串是否為父字符串的后綴
    fmt.Println("-------------------------------")
    fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "lia"))
    fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "tia"))

    //子字符串首次出現在父子符串的索引下標
    fmt.Println("-------------------------------")
    fmt.Println("Index Function:",strings.Index("Australia", "lia"))
    fmt.Println("Index Function: ",strings.Index("Australia", "a"))
    fmt.Println("Index Function: ",strings.Index("Australia", "A"))

    //連接函數，指定分隔符將字符串連接起來
    fmt.Println("-------------------------------")
    fmt.Println("Join Functions:",strings.Join([]string{"Austrilia", "Japen", "Germany"}, "-"))
    fmt.Println("Join Function: ",strings.Join([]string{"Australia","Japan","Germany"}," "))

    //重復函數，指定字符串重復出現的次數
    fmt.Println("-------------------------------")
    fmt.Println("Repeat Function:", strings.Repeat("Australia",3))

    //替換字符串函數，
    fmt.Println("-------------------------------")
    fmt.Println("Replace Function: ",strings.Replace("Australia ","a","b",1))
    fmt.Println("Replace Function: ",strings.Replace("Australia ","a","b",2))
    fmt.Println("Replace Function: ",strings.Replace("Aaustralia ","a","b",3))
    fmt.Println("Replace Function: ",strings.Replace("Australia ","A","B",1))
    fmt.Println("Replace Function: ",strings.Replace("Australia ","lia","pia",1))

    //分割函數，指定分隔符分隔字符串
    fmt.Println("-------------------------------")
    fmt.Println("Split Function:", strings.Split("Australia-Japan-Germany","-"))

    //把字符轉小寫
    fmt.Println("-------------------------------")
    fmt.Println("ToLower Function: ",strings.ToLower("Australia"))

    //把字符串轉大寫
    fmt.Println("-------------------------------")
    fmt.Println("ToUpper Function: ",strings.ToUpper("Australia"))
