(như bạn đã làm với các mảng nhật ký tại Phòng thí nghiệm 1), nhưng điểm ADT Danh sách của bạn sẽ được linh hoạt hơn nếu bạn chỉ định kích thước của mảng trong thời gian chạy và tự động phân bổ bộ nhớ cần thiết để lưu trữ nó. Cấp phát bộ nhớ cho mảng được thực hiện bởi các nhà xây dựng. | LABORATORY 3 LABORATORY 3 In-lab Exercise 3 Name_ Hour Period Section_ Date_ Strings can also be read and written in a Java GUI. A correct implementation of the DrawCurv program in Laboratory 2 In-lab 2 generates a simple drawing of a set of points the program connects the dots. A more interactive GUI that prints and accepts text will be developed in this lab exercise. In this process the console application of the Hangman program from In-lab 2 will be converted to a frame-based graphical application much like the DrawCurv program in Laboratory 2 In-lab 1 was converted to a graphical application in Laboratory 2 In-lab 2. First it will not be necessary in this Hangman graphical application to import . so remove that import statement from your program. In this program it is intended that all I O will occur in the GUI. Only the import statements used in the DrawCurv program will be needed here. The data members in the HangmanFrame class will include most of the variables used in the non-GUI Hangman implementation from In-lab 2 such as secretword guessLetter numGuesses and guessTemplate plus the following graphic components private TextField guessedTxt secretTxt private Label secretLbl tempLbl guessLbl for input of guessLetter for input of secretword message for secretword text field displays the guessTemplate message for guessLetter text field These graphic components will be defined and added to the frame in the constructor for the HangmanFrame class. Several statements need to be included in the HangmanFrame constructor. Along with other basic frame setup statements like setTitle and setsize include the setLayout method statement and its single argument as illustrated below. implement a simple layout similar to how text flows on a page setLayout new FlowLayout The setLayout method governs how multiple components will be arranged in the Hangman frame. The FlowLayout .
