JAVA Certification SCJP : operators

Here is an SCJP certification exercise about operators.

Exercice :

class Arg {

public static void main(String[] args){
int i = 6;
if ( i && 12 ){
System.out.println("OK!");
} else {
System.out.println("KO!");
}
}
}
What is the result ?
A : OK!
B : KO!
C : compilation fails
D : An exception is thrown at runtime




Soultion :

The compilation will fail because of i && 12.The && and || work with boolean operators only !
