如何设置JavaFXTextArea的高度和宽度？

我调用什么方法来设置此

文本区域的高度和宽度？
setPrefColumnCount（）和setPrefRowCount（）工作得更好：

TextArea textArea = new TextArea(); //making a TexrArea object
double height = 400; //making a variable called height with a value 400
double width = 300;  //making a variable called height with a value 300

//You can use these methods
textArea.setPrefHeight(height);  //sets height of the TextArea to 400 pixels 
textArea.setPrefWidth(width);    //sets width of the TextArea to 300 pixels

setPrefColumnCount（）
和
setPrefRowCount（）
应该为您做这件事。谢谢你的建议，请考虑添加一些细节和解释来支持你的答案，以帮助他人。
TextArea textArea = new TextArea(); //making a TexrArea object
double height = 400; //making a variable called height with a value 400
double width = 300;  //making a variable called height with a value 300

//You can use these methods
textArea.setPrefHeight(height);  //sets height of the TextArea to 400 pixels 
textArea.setPrefWidth(width);    //sets width of the TextArea to 300 pixels

TextArea textArea = new TextArea();
double prefWidth = 1.0
double prefHeight = 1.0
textArea.setPrefSize(prefWidth, prefHeight);
