Java swing组件的串行化和读取
由于JButton和JTree都已经实现了Serializable接口 因此Java swing组件的串行化和读取是可以做到的 方法就是使用ObjectInputStream读取文件中的对象 使用ObjectOutputStream把对象写入文件
如
import java io FileInputStream;import java io FileNotFoundException;import java io FileOutputStream;import java io IOException;import java io ObjectInputStream;import java io ObjectOutputStream;
import javax swing JButton;import javax swing JTree;
public class Save {
public static void main(String[] args) {
// WriteJButton button = new JButton( TEST Button );JTree tree = new JTree();try {ObjectOutputStream outForButton = new ObjectOutputStream(new FileOutputStream( button ));outForButton writeObject(button);outForButton close();ObjectOutputStream outForTree = new ObjectOutputStream(new FileOutputStream( tree ));outForTree writeObject(tree);outForTree close();} catch (FileNotFoundException e) {e printStackTrace();} catch (IOException e) {e printStackTrace();}// Read
try {ObjectInputStream inForButton = new ObjectInputStream(new FileInputStream( button ));JButton buttonReaded = (JButton) inForButton readObject();
ObjectInputStream inForTree = new ObjectInputStream(new FileInputStream( tree ));JTree treeReaded = (JTree) inForTree readObject();} catch (FileNotFoundException e) {e printStackTrace();} catch (IOException e) {e printStackTrace();} catch (ClassNotFoundException e) {// TODO Auto generated catch blocke printStackTrace();}
}
}
