Go Struct (struct)Go Method (Method)

Go Same Name Method

In Go language, it is allowed to create two or more methods with the same name in the same package, but these methods must have different receiversmust have different typesThis feature is not available in Go functions, which means it is not allowed to create methods with the same name in the same package. If you try to do so, the compiler will throw an error.

Syntax:

func(receiver_name_1　Type) method_name(parameter_list)(return_type){
　　　　//　Code
}
func(receiver_name_2　Type) method_name(parameter_list)(return_type){
　　　　//　Code
}

Let's discuss this concept with an example:

Example1:

Example

package  main　
　　
import  "fmt"
　　
//Create structure
type  student  struct  {　
　　　　name      string　
　　　　branch  string　
}　
　　
type  teacher  struct  {　
　　　　language  string　
　　　　marks      int
}　
　　
//Methods with the same name but different receiver types
func  (s  student)  show()  {　
　　
　　　　fmt.Println("Student Name:  ",  s.name)　
　　　　fmt.Println("Branch:  ",  s.branch)　
}　
　　
func  (t  teacher)  show()  {　
　　
　　　　fmt.Println("Language:  ",  t.language)　
　　　　fmt.Println("Student  Marks:  ",  t.marks)　
}　
　　
func  main()  {　
　　
　　　　//　Initialize the value of the structure
　　　　val1　:=  student{"Rohit",  "EEE"}　
　　
　　　　val2　:=  teacher{"Java",　50}　
　　
　　　　//Call method
　　　　val1.show()　
　　　　val2.show()　
}

Output:

Student Name:  Rohit
Branch:  EEE
Language:  Java
Student  Marks:　　50

Usage instructions:In the above example, we have two methods with the same name, namelyshow(),but the receiver types are different. Here, the firstshow()method contains a receiver of type s student, the secondshow()method contains a receiver of type t teacher. Inmain()In the function, we use the respective struct variables to call these two methods. If you try to use the same type receiver to create thisshow()If the compiler throws an error when the same type receiver is created for this method in the function.

Example2:

Example

//Create methods with the same name
//Non-structured type receiver
package  main　
　　
import  "fmt"
　　
type  value_1　string　
type  value_2　int
　　
//Create functions with the same name
//Non-structured receiver of different types
func  (a  value_1)  display()  value_1　{　
　　
　　　　return  a　+　".com"
}　
　　
func  (p  value_2)  display()  value_2　{　
　　
　　　　return  p　+　298　
}　
　　
func  main()  {　
　　
　　　　//Initial value　
　　　　res1　:=  value_1("w3codebox)　
　　　　res2　:=  value_2(234)　
　　
　　　　//　Print display result
　　　　fmt.Println("Result　1:  ",  res1.display())　
　　　　fmt.Println("Result　2:  ",  res2.display())　
}

Output:

Result　1:　　oldtoolbag.com
Result　2:　532
