whats wrong with the code

Question

public class MyProgram{

public static void PalindromeNumber(int n){
int sum = 0;
int b = n;

while(n>0){
int a = n%10;
sum = (sum*10) + a;
n = n/10;
}

if(sum == b){
System.out.println(b+" is palindrome number");
}

else{
System.out.println(b+" is not palindrome number");
}

public static void main(String[] args){
PalindromeNumber(393);
}

}
}

when i call the method PalindromeNumber from another class it works
but not within its own class why

Answer 1

methods P..() ends after main(), it is wrong, correct it this way:

} // add bracket here
public static void main(String[] args) {
PalindromeNumber(393);
}
// } delete this bracket
}
