Which are correct input-output options :

public class Example6{
public static void main(String args[])
{
public int check(char a) {
if (a <= 'N') {
if (a == 'E')
return 2;
return 1;
} else if (a == 'S')
return 3;
else if (a == 'W')
return 4;
return 0; }
}
}

Options are :

(1) a='A' output=1.

(2)Compile error.

(3) a='X' output=0,

(4)a='D' output=0.

Answer :

(1) & (3)

Explanation :

Since 'Ascii' value of 'D' is less than 'Ascii' value of 'N', so it's output will be 1.That's why it(4) is not correct option to choose.
