 Hi Guys,

Welcome to Java Inspires.

In this post, we will see how to create a Slice in go lang using make function and also how to add elements to the slice.

sample.go

package main

import "fmt"

func main() {

	//create a string type slice
	var strSlice = make([]string, 5) // here length and capacity is 5

	//print strSlice
	fmt.Println("strSlice :", strSlice)
	// print length of slice
	fmt.Println("Length of strSlice :", len(strSlice))
	//print capacity of strslice
	fmt.Println("Capacity od strSlice :", cap(strSlice))

	// lets create a slice with different length and different capacity
	var strSl = make([]string, 5, 8) // here 5 is length and 8 is capacity
	// print capacity and length
	fmt.Println("Length of strS1 :", len(strSl))
	fmt.Println("Capacity of strS1 :", cap(strSl))
	// now add element to the slice
	strSl[0] = "Hello"
	strSl[1] = "Java"
	strSl[2] = "Inspires"
	//print the slice
	fmt.Println(strSl)
}

Output :

PS C:\Users\developer\Desktop> go run .\sample.go
strSlice : [    ]
Length of strSlice : 5  
Capacity od strSlice : 5
Length of strS1 : 5     
Capacity of strS1 : 8   
[Hello Java Inspires  ] 
PS C:\Users\developer\Desktop> 

THANK YOU
