回答by Michael Cenzoprano
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
回答by HashTables
setPrefColumnCount() and setPrefRowCount() worked
setPrefColumnCount() 和 setPrefRowCount() 有效

Even better:
更好的是：
TextArea textArea = new TextArea();
double prefWidth = 1.0
double prefHeight = 1.0
textArea.setPrefSize(prefWidth, prefHeight);
