go语言字符串练习

package main

import "fmt"
import s"strings"

var p = fmt.Println

func main() {
    p("Contains: ",s.Contains("test","es"))
    p("Count: ",s.Count("test","t"))
    p("hasPrefix: ",s.HasPrefix("test","te"))
    p("HasSuffix: ",s.HasSuffix("test","st"))
    p("index: ",s.Index("test","e"))
    p("Join; ",s.Join([]string{"a","b"},"-"))
    p("Repeat: ",s.Repeat("a",5))
    p("Replace: ",s.Replace("foo","o","0",-1))
    p("Replace: ",s.Replace("foo","o","0",1))
    p("Split: ",s.Split("a-b-c-d-e","-"))
    p("ToLower: ",s.ToLower("TEST"))
    p("ToUpper: ",s.ToUpper("test"))
    p()

    p("Len: ",len("hello"))
    p("Char: ","hello"[1])
}

显示如下

Contains: true
Count: 2
hasPrefix: true
HasSuffix: true
index: 1
Join; a-b
Repeat: aaaaa
Replace: f00
Replace: f0o
Split: [a b c d e]
ToLower: test
ToUpper: TEST

Len: 5
Char: 101
