Why my code has 2 errors?

Question

import java.util.*;
public class Program
{
public static void CheckEven(int n){
if(n%2==0){
System.out.println("even");
}else{
System.out.println("not even given num..");
}
}
// int i=1,count=0;
/*while(i<=n){
if(n%i==0){
count=count+1;
i++;
}
if(count==2){
System.out.println("the given number is prime");
}
else{
System.out.println("the given number is not prime number");
}
}*/
public static void main(String[] args) {
Scanner sc= new Scanner(System.in);
n=sc.nextInt();
CheckEven(int n);
}//please anybody tell me why my code have two errors
}

Answer 1

1. No type definition specified for variable <n>
Include data type when declaring <n>

int n = sc.nextInt();

2. On the contrary, no type specification used when calling a method

CheckEvent(n); // no type specific for method call argument(s)
