my question is can catch block itself return null as return as soon as it comes out of if block and comes inside catch block

class Exc2 {
public static void main(String args[]) {
int d, a;
try { // monitor a block of code.
d = 0;
a = 42 / d;
System.out.println("This will not be printed.");
} catch (ArithmeticException e) { // catch divide-by-zero
//error
System.out.println("Division by zero.");
return null;//can i do this??? any way flow did not go through 'if' loop then it can only go to 'else' loop right? is there is scenario flow does not go through 'if' or 'try'
}

return null;//is this is needed???
System.out.println("After catch statement.");
}
}
