法律研究如何在 Golang 中連線兩個字串？
在 Golang 中連線兩個字串的最簡單方法是使用“+”運算子。例如，
示例 1
package main
import (
"fmt"
)
func main() {
str1 := "Hello..."
str2 := "How are you doing?"
fmt.Println("1st String:", str1)
fmt.Println("2nd String:", str2)
// Concatenate using the + Operator
fmt.Println("Concatenated String:", str1 + str2)
}輸出
將產生以下輸出
1st String: Hello... 2nd String: How are you doing? Concatenated String: Hello...How are you doing?
使用 strings.Join() 連線
strings.Join() 是 Golang 中內建的一個函式，用於將多個字串連線成一個字串。
語法
其語法如下：
func Join(stringSlice []string, sep string) string
其中：
- stringSlice – 要連線的字串。
- sep – 要放在切片元素之間的分隔字串。
示例 2
讓我們考慮以下示例：
package main
import (
"fmt"
"strings"
)
func main() {
// Initializing the Strings
m := []string{"IndexByte", "String", "Function"}
n := []string{"Golang", "IndexByte", "String", "Package"}
// Display the Strings
fmt.Println("Set 1 - Slices of Strings:", m)
fmt.Println("Set 2 - Slices of Strings:", n)
// Using the Join Function
output1 := strings.Join(m, "-")
output2 := strings.Join(m, "/")
output3 := strings.Join(n, "*")
output4 := strings.Join(n, "$")
// Display the Join Output
fmt.Println("\n Joining the slices of Set 1 with '-' delimiter: \n", output1)
fmt.Println("\n Joining the slices of Set 1 with '/' delimiter: \n", output2)
fmt.Println("\n Joining the slices of Set 2 with '*' delimiter: \n", output3)
fmt.Println("\n Joining the slices of Set 2 with '$' delimiter: \n", output4)
}輸出
它將生成以下輸出：
Set 1 - Slices of Strings: [IndexByte String Function] Set 2 - Slices of Strings: [Golang IndexByte String Package] Joining the slices of Set 1 with '-' delimiter: IndexByte-String-Function Joining the slices of Set 1 with '/' delimiter: IndexByte/String/Function Joining the slices of Set 2 with '*' delimiter: Golang*IndexByte*String*Package Joining the slices of Set 2 with '$' delimiter: Golang$IndexByte$String$Package
示例 3
我們再來看一個示例。
package main
import (
"fmt"
"strings"
)
func main() {
// Defining the Variables
var s []string
var substr string
var substr1 string
var result string
var output string
// Intializing the Strings
s = []string{"This", "is", "String", "Function"}
substr = "..."
substr1 = " "
// Display the input slice of strings
fmt.Println("Input Slice of Strings:", s)
// Using the Join Function
result = strings.Join(s, substr)
output = strings.Join(s, substr1)
// Displaying output of Join function
fmt.Println("Joining with '...' delimiter:", result)
fmt.Println("Joining with ' ' delimiter:", output)
}輸出
它將生成以下輸出：
Input Slice of Strings: [This is String Function] Joining with '...' delimiter: This...is...String...Function Joining with ' ' delimiter: This is String Function
