字符串函数在golang中的使用

package main

import (
	"fmt"
	"strings"
)

func main()  {
	//判断父字符串是否包含子字符串，包含为真，否则为假
	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现的次数
	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"))

	//判断子字符串是否为父字符串的前缀
	fmt.Println("-------------------------------")
	fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Bu"))
	fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Aus"))

	////判断子字符串是否为父字符串的后缀
	fmt.Println("-------------------------------")
	fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "lia"))
	fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "tia"))

	//子字符串首次出现在父子符串的索引下标
	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"))

	//连接函数，指定分隔符将字符串连接起来
	fmt.Println("-------------------------------")
	fmt.Println("Join Functions:",strings.Join([]string{"Austrilia", "Japen", "Germany"}, "-"))
	fmt.Println("Join Function: ",strings.Join([]string{"Australia","Japan","Germany"}," "))

	//重复函数，指定字符串重复出现的次数
	fmt.Println("-------------------------------")
	fmt.Println("Repeat Function:", strings.Repeat("Australia",3))

	//替换字符串函数，
	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))

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

	//把字符转小写
	fmt.Println("-------------------------------")
	fmt.Println("ToLower Function: ",strings.ToLower("Australia"))

	//把字符串转大写
	fmt.Println("-------------------------------")
	fmt.Println("ToUpper Function: ",strings.ToUpper("Australia"))

}
