JavaFX 텍스트 영역 : 각 줄의 끝에 "-"을 추가하십시오.

Question

이것은 내 첫 번째 게시물입니다.

NetBeans IDE를 사용하고 있으며 JavaFX 프로젝트에 Scene Builder를 사용하고 있습니다. "-" 가 나는 또한 내가로 끝나는 텍스트 영역에서 라인을 만들려고 노력하고있는 액션

void addAction(ActionEvent event) { 
} 

와 버튼이 변수 "정의" 와 텍스트 영역이있다.

는 시각화 : 입력 :

happy 
sad 
good 
bad 

출력 :

happy - 
sad - 
good - 
bad - 

I 루프이있다 :

for (int i = 0 ; definitions.getText().split("\\n"); i++){ 
     String previous = definitions.getText(); 
     definitions.setText(previous + " - "); 
     } 

되지만 출력은 :

happy 
sad 
good 
bad - - - - 

누군가 나를 도와 줄 수 있습니까? 감사합니다. MineRockers 여기

이 코드 추가를 "-"어떤 줄 뒤에 :

가

String str = definitions.getText().replaceAll("\n", " -\n"); 
str = str + " -";// add "-" to last line 
definitions.setText(str);
