重用样式对象

重用样式对象可以节省内存并使程序执行得更快。

将某些格式应用于工作表中的大范围单元格：

1. 创建样式对象。
2. 指定属性。
3. 将样式应用于范围内的单元格。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(ReuseStyleObjects.class);
// Create an instance of Workbook & load an existing spreadsheet
Workbook workbook = new Workbook(dataDir + "Book1.xls");

// Retrieve the Cell Collection of the first Worksheet
Cells cells = workbook.getWorksheets().get(0).getCells();

// Create an instance of Style and add it to the pool of styles
Style styleObject = workbook.createStyle();

// Retrieve the Font object of newly created style
Font font = styleObject.getFont();

// Set the font color to Red
font.setColor(Color.getRed());

// Set the newly created style on two different cells
cells.get("A1").setStyle(styleObject);
cells.get("A2").setStyle(styleObject);

与上面讨论的相同过程也可以如下完成。

cells.get("A1").getStyle().getFont().setColor(Color.getRed());
cells.get("A2").getStyle().getFont().setColor(Color.getRed());

因为[Cell.getStyle](https://reference.aspose.com/cells/java/com.aspose.cells/cell#getStyle() ） 和[Cell.setStyle](https://reference.aspose.com/cells/java/com.aspose.cells/cell#setStyle(com.aspose.cells.Style) 方法使用更少的内存并且效率更高，越老Cell.getStyle()消耗大量不必要内存的属性随着Aspose.Cells 7.1.0.
