我在将arraylist导出为CSV / XLS文件时遇到了困难。我该怎么做？也许使用POI API？但我真的不知道我可以从哪里开始......
任何人都可以帮助我吗？非常感谢你; - ）
表类：
public abstract class TestTable extends JFrame {
protected static FileData FileData = new FileData();
public static void main(String args[]) {
{
JFrame meinFrame = new JFrame("Beispiel JFrame");
JTable fileTable = new JTable(TestTable.FileData);
JScrollPane scrollPane = new JScrollPane(fileTable);
meinFrame.getContentPane().add(scrollPane, BorderLayout.CENTER);
meinFrame.setSize(500, 500);
meinFrame.setVisible(true);
}
}
}
arraylist的代码：
public class FileData extends AbstractTableModel implements FilenameFilter {
List<Object[]> data = new ArrayList<>();
String titles[] = new String[] { "File Name", "Path" };
Class<?> types[] = new Class[] { String.class, String.class };
public FileData() {
this("C:\\");
}
public FileData(String directory) {
File inputFiles = new File(directory);
setFileStats1(inputFiles);
}
public int getRowCount() {
return this.data.size();
}
public int getColumnCount() {
return this.titles.length;
}
public String getColumnName(int column) {
return this.titles[column];
}
public Class<?> getColumnClass(int column) {
return this.types[column];
}
public Object getValueAt(int row, int column) {
return this.data.get(row)[column];
}
public void setFileStats1(final File directory) {
this.data = new ArrayList<>();
for (File file : directory.listFiles()) {
this.data.add(new Object[] { file.getName(), file.getAbsolutePath() });
}
}
public boolean accept(File directory, String name) {
// TODO Auto-generated method stub
return false;
}
}
