是否可以不必重新输入所有这些几乎相同的程序？
cancelSaveContactBtn.setVisible(false);
saveContactBtn.setVisible(false);
addContactBtn.setVisible(true);
和
selectContactCBox.addActionListener(this);
addContactBtn.addActionListener(this);
personalRadio.addActionListener(this);
businessRadio.addActionListener(this);

从技术上讲，如果您打算在一组对象上使用相同的参数调用相同的方法，则可以使用List来存储对象，迭代并为每个对象设置abstract class CharacterClass {
private String characterClass;
private int level;
private int hp;
private int strength;
private int constitution;
private int dexterity;
private int intelligence;
private int wisdom;
private int charisma;
protected CharacterClass(){
setCharacterClass("Character Class");
setLevel(1);
setHp(10);
setStrength(10);
setConstitution(10);
setDexterity(10);
setIntelligence(10);
setWisdom(10);
setCharisma(10);
}
public String getCharacterClass() { return characterClass; }
public int getLevel() { return level; }
public int getHp() { return hp; }
public int getStrength(){ return strength; }
public int getConstitution(){ return constitution; }
public int getDexterity(){ return dexterity; }
public int getIntelligence(){ return intelligence; }
public int getWisdom(){ return wisdom; }
public int getCharisma(){ return charisma; }
protected void setCharacterClass(String characterClass){ this.characterClass = characterClass; }
protected void setLevel(int lvl){ level = lvl; }
protected void setHp(int hitPoints){ hp = hitPoints; }
protected void setStrength(int str){ strength = str; }
protected void setConstitution(int con){ constitution = con; }
protected void setDexterity( int dex) { dexterity = dex; }
protected void setIntelligence(int intel){ intelligence = intel; }
protected void setWisdom(int wis){ wisdom = wis; }
protected void setCharisma(int cha){charisma = cha; }
}
class Fighter extends CharacterClass {
Fighter(){
setCharacterClass("Fighter");
setLevel(1);
setHp(10);
setStrength(14);
setConstitution(16);
setDexterity(14);
setIntelligence(10);
setWisdom(10);
setCharisma(10);
}
}
。
