字串和數字的轉換

 int count = Integer.parseInt("100");

float value = Float.parseFloat("100.33");

自動生成getter & setter

1. 設定member variable的開頭字串

ADT -> Preferences -> Java -> Code Style

2. 生成getter & setter

Source -> Generate Getters & Setters

ex:

public class TrueFalse {

  private int mQuestion;

   private boolean mTrueQuestion;

   public TrueFalse(int question, boolean trueQuestion) {

       mQuestion = question;

       mTrueQuestion = trueQuestion;

   }

public int getQuestion() {

return mQuestion;

}

public void setQuestion(int question) {

mQuestion = question;

}

public boolean isTrueQuestion() {

return mTrueQuestion;

}

public void setTrueQuestion(boolean trueQuestion) {

mTrueQuestion = trueQuestion;

}

}
