How do I complete the second step of the Knock Knock joke?

I've successfully completed the first part of this problem and after many tries I am still not able to figure out the second part of the problem. If you could paste the answer with an explanation that would be greatly appreciated!

String who;

do { console.printf("Knock Knock.\n"); who = console.readLine("Who's there? ");

for the first one you can do as follows. String who;

do {
    console.printf("Knock Knock.\n");
    who = console.readLine("Who's there?  ");
    console.printf("%s who?\n", who);
} while (who.equalsIgnoreCase("banana"));

but for the second task you can use the if statement as follows

if (who.equalsIgnoreCase("orange")){
console.printf("%s i am glad you are not another Banana", who);
}
