Practice problem with arrays issue

/*program asks the user to use specific keys to unlock specific keys,
 if the wrong key is used on the wrong key it explodes and ends the program */
import java.util.Scanner; 
public class Keygame {
public static void main(String[] args){ 
Scanner input = new Scanner(System.in); 
String[] key = {"Skeleton key", "Stone key", "Wood key", "plastic key" };

System.out.println("Before you are 4 keys. \n Each key take a different key. \n You have each key in your bag but be careful. \n Using the wrong key will cause the key to explode.\n");
System.out.println("please type a number corresponding to the one beside each key \n"); 
for(int i = 0; i < key.length; i++){
    System.out.println(i+1 + "." + key[i]);  
}
int pkey = input.nextInt(); 

if(pkey >= 1 && pkey <= key.length){
    int chosenkey = pkey - 1; 
    System.out.println(" you chose " + key[chosenkey]); 
}
else{
    System.out.println("You have chosen the (INSTANT DEATH IF YOU CHOOSE IT key) \n you will now instantly die \n game over ");
}

String[] door = {"Skeleton door", "Stone door", "Wood door", "plastic door" };

System.out.println("\nplease type a number corresponding to the one beside each door"); 

for(int i = 0; i < door.length; i++){
    System.out.println(i+1 + "." + door[i]); 
}
int pdoor = input.nextInt();

if(pdoor >= 1 && pdoor <= door.length){
    int chosendoor = pdoor - 1; 
    System.out.println(" you chose " + door[chosendoor]); 
}
else{
    System.out.println("You have chosen the (INSTANT DEATH IF YOU CHOOSE IT key) \n you will now instantly die \n game over ");
}
// print out what key and door you have chosen
System.out.println("you are unlocking the " + door + " with " + key); 
}
}

cant seem to figure out how to print out the arrays the user chooses, no matter what i do it either prints out the number of the array or the memory address.

Method repeating issue

I'm trying to figure out how to repeat the method while having the new one add the new input to the previous input. I haven't been able to figure this out and have been stuck on it for a while. here's what I currently have currently public static void problem1(){ System.out.println("Problem 1"); //Code for problem 1 here. int Ans; // asks the user how many temperatures they would like to input do{ Scanner input = new Scanner(System.in); System.out.println("please input the temperatures in degrees farenheit"); int temp = input.nextInt(); int[] tempNum = new int[temp]; int total = temp+temp; int average = total/tempNum[temp]; if(temp < 32){ System.out.println(" temperatures are below freezing"); } else if(temp == 32){ System.out.println(" temperatures are freezing"); } else if(temp > 32){ System.out.println(" temperatures are above freezing"); } System.out.println("The average is " + average); System.out.println("Would you like to input another temperature? Type 1 for yes and 2 for no"); Ans = input.nextInt(); //asks if the user would like to input another temp if(Ans == 2){ System.out.println("thank you and goodbye"); // shuts off when user inputs 2 System.exit(0); } else if( Ans > 2){ System.out.println("Please input a valid option"); System.exit(0); } } while(Ans == 1); // loops when user inputs 1 }
