私はバイナリツリープログラムを作成しました。このプログラムは、特定の動物について学ぶための質問をユーザーに求めています。whileループ/プログラムの再起動
私の問題は、私のプログラムがユーザーに「続行しますか?」と尋ねるときです。私はループを再開したいが、これをどうやって達成するかはわからない。私のwhileループでは2回、一番下の学習メソッドでは1回発生します。誰かが私がこれをどのように達成できるかについてのアイデアはありますか?
import java.util.*;
public class AnimalGuessing {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
TreeNode<String> leftTree = new TreeNode<String> ("cat");
TreeNode<String> rightTree = new TreeNode<String> ("snake");
TreeNode<String> gameTree = new TreeNode<String>("Does it have legs?",leftTree,rightTree);
TreeNode<String>curr = gameTree;
String response;
System.out.println("");
System.out.println("");
System.out.println("Think of an animal and I will guess it.");
while(!(curr.getLeft() == null && curr.getRight()==null)){
System.out.print(curr.getItem());
response = scan.nextLine();
if (response.equals("YES")){
curr = curr.getLeft();
System.out.print("Is it a " + curr.getItem() + "?");
response = scan.nextLine();
if (response.equals("YES")){
System.out.println("I win! Continue?");
response = scan.nextLine();
if (response.equals("YES")){
//-----------------------
// I want it to restart
// the while loop here!
//-----------------------
}
else{
System.out.println("Good-bye.");
}
}
else{
learn(curr);
}
}//end if
if (response.equals("NO")){
curr = curr.getRight();
System.out.println("is it a " + curr.getItem() + "?");
response = scan.nextLine();

System.out.println("I win! Continue?");
response = scan.nextLine();

public static void learn(TreeNode<String> current){

THank you!これは大いに役立ちます。 – Bell
問題ありません^^。私はまた、あなたがすべての機能を置くことをお勧めします –
どういう意味ですか?メソッドのように? – Bell
