In Go language, strings are encoded using UTF-8Immutable sequence of arbitrary bytes encoded. You can compare strings in two different ways:
1. Use comparison operators:Go to string support comparison operators, that is==, !=, >=, <=, <, >. Here,==And!=Operators are used to check if the given string is equal. And >=, <=, <, > operators are used to find lexical order. These operators return a boolean type, meaning that if the condition is met, it returnstrueOtherwise returnfalse。
Examples of string == and != operators1:
//String comparison operators == and != package main import "fmt" func main() { //Create and initialize a string //Using abbreviated declarations str1 := "Geeks" str2 := "Geek" str3 := "w3codebox" str4 := "Geeks" //Check if the strings are equal //Using == operator result1 := str1 == str2 result2 := str2 == str3 result3 := str3 == str4 result4 := str1 == str4 fmt.Println("Result 1: ", result1) fmt.Println("Result 2: ", result2) fmt.Println("Result 3: ", result3) fmt.Println("Result 4: ", result4) //Check if the strings are not equal //Using != operator result5 := str1 != str2 result6 := str2 != str3 result7 := str3 != str4 result8 := str1 != str4 fmt.Println("\nResult 5: ", result5) fmt.Println("Result 6: ", result6) fmt.Println("Result 7: ", result7) fmt.Println("Result 8: ", result8) }
Output:
Result 1: false Result 2: false Result 3: false Result 4: true Result 5: true Result 6: true Result 7: true Result 8: false
Examples of string comparison operators2:
//String comparison operators package main import "fmt" func main() { //Creation and initialization //Using shorthand declarations myslice := []string{"Geeks", "Geeks", "gfg", "GFG", "for"} fmt.Println("Slice: ", myslice) //Using comparison operators result1 := "GFG" > "Geeks" fmt.Println("Result 1: ", result1) result2 := "GFG" < "Geeks" fmt.Println("Result 2: ", result2) result3 := "Geeks" >= "for" fmt.Println("Result 3: ", result3) result4 := "Geeks" <= "for" fmt.Println("Result 4: ", result4) result5 := "Geeks" == "Geeks" fmt.Println("Result 5: ", result5) result6 := "Geeks" != "for" fmt.Println("Result 6: ", result6) }
Output:
Slice: [Geeks Geeks gfg GFG for] Result 1: false Result 2: true Result 3: false Result 4: true Result 5: true Result 6: true
2.Using Compare() method:You can also use the built-in function Compare() provided by the string package to compare two strings. After comparing two strings, this function returns an integer value. The return value is:
Ifstr1 == str2,then return 0 .
Ifstr1> str2,return1 。
Ifstr1 <str2,Returns-1 。
Syntax:
func Compare(str1, str2 string) int
//Strings use the compare() function package main import ( "fmt" "strings" ) func main() { //Comparing strings using comparison functions fmt.Println(strings.Compare("gfg", "Geeks")) fmt.Println(strings.Compare("w3codebox", "w3codebox")) fmt.Println(strings.Compare("Geeks", " GFG")) fmt.Println(strings.Compare("GeeKS", "GeeKs")) }
Output:
1 0 1 -1
