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",))
     p("Replace: ",s.Replace("foo","o","",-))
     p("Replace: ",s.Replace("foo","o","",))
     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"[])
 }

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
