Question

java kendo upload 怎么指定文件类型，比如设置doc，选择文件时，只看到.doc的文件

Answer 1

以下代码弹出一个针对用户主目录的文件选择器，其中只显示 .jpg 和 .gif 图像：

JFileChooser chooser = new JFileChooser();
// Note: source for ExampleFileFilter can be found in FileChooserDemo,
// under the demo/jfc directory in the JDK.
ExampleFileFilter filter = new ExampleFileFilter();
filter.addExtension("jpg");
filter.addExtension("gif");
filter.setDescription("JPG & GIF Images");
chooser.setFileFilter(filter);
int returnVal = chooser.showOpenDialog(parent);
if(returnVal == JFileChooser.APPROVE_OPTION) {
System.out.println("You chose to open this file: " +
chooser.getSelectedFile().getName());
}
