GuessGame（）メソッドにある値を格納し、JTextfieldfindMiddleNumber（）にある配列にそれらを配置しようとすると問題が発生します。プログラムが終了したときに取得するのは、randomNumberであるユーザーからの最後の入力だけです。

誰かが私のコードを見て、どこが間違っているのか見てください。

you need to take the input from the user when they are coming and store them. in your actionPerformed() which is talking value from JTextField, store the these values in a array test[], then you call your ProcessGuessedNumber, then if it matches, your findmidlenumber is called, which i don't know why you used to take input from system.in and storing them in an array when inputGuess matches randomNumber, so obvioulsy your inputGuess latest value will be the last one, which is the randomNumber.

Take user input in array when he is entering them, the control will automatically move to your middleNumer() if it is equal to the randomNumber. so, in your GuessHandler's actionPerformed():

 public void actionPerformed ( ActionEvent event )
{
    inputGuess = Integer.parseInt( guessInput.getText() );
    test[i]= inputGuess;
    processGuessedNumber( inputGuess );
    i++;

}

then use this array to calculate whatever you want, like:

middleNumber = test[( i)/ 2]; 
System.out.printf( "\nMiddle is: " + middleNumber);
finalOutput();
