so I am new to java and wrote this code. why it gives me error?

Question

package java_learning;

public class main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
    
        System.out.println("what is your name?");
        String name = scanner.nextLine();
        
        System.out.println("hello"+name);
        
        
                
    }

}

the error is Exception in thread "main" java.lang.Error: Unresolved compilation problems: Scanner cannot be resolved to a type scanner cannot be resolved to a type

at java_learning.main.main(main.java:7)

Need to `import java.util.Scanner;` Also note that it's **S**canner, not **s**canner. — Robby Cornelissen, Oct 19 '21 at 06:16
`new Scanner` with a capital `S`. Use an IDE like Eclipse or Intellij to avoid these things. — Renis1235, Oct 19 '21 at 06:16

First of all import the package

import java.util.Scanner

Then just change the new scanner() to new Scanner()

Final code :

package java_learning;

import java.util.Scanner;

public class main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
    
        System.out.println("what is your name?");
        String name = scanner.nextLine();
        
        System.out.println("hello"+name);
        
        
                
    }

}

You got an typo in this line:

Scanner scanner = new scanner(System.in);

It needs to be:

Scanner scanner = new Scanner(System.in);

Import this , import java.util.scanner; and the s in the new scanner is small, make it Big "S"

You need to import this library as import java.util.Scanner; and update new scanner line as new Scanner()
