What's wrong in my code? Why is it giving error?

Question

import java.util.Scanner;
public class check{
public static void main(String[]args){
boolean a;
Scanner a=new Scanner(System.in);
System.out.println(a.nextBoolean());
if (a==0)
System.out.println("Fail");
else
System.out.println("Pass");
}
}

Answer 1

you're using scanner in wrong way, you can consider scanner used as utilities to get an input, not store the input. so you need to create another variable to store them.
and dont use same name for 2 different variable.

boolean x;
x = a.nextBoolean();

then you can use x for your if condition
