设置JTable中列的数据类型

I created a JTable with a table model . Now based on an input which i have, i want to make one column into a particular data Type. How do i do this?import java.awt.GridLayout;import javax.swing.*;import javax.swing.event.*;import javax.swing.table.AbstractTableModel;public class MyTableModelTwo extends AbstractTableModel { private static final long serialVersionUID = 1L; private Object[][] data; private String[] columnNames; public MyTableModelTwo(Object[][] data) { this.data = data; } @Override public int getRowCount() { return data.length; } @Override public int getColumnCount() { return columnNames.length; } @Override public Object getValueAt(int rowIndex, int columnIndex) { return data[rowIndex][columnIndex]; } @Override public Class<?> getColumnClass(int c) { return getValueAt(0, c).getClass(); } @Override public boolean isCellEditable(int rowIndes, int columnIndex) { return true; } @Override public String getColumnName(int index) { return columnNames[index]; } @Override public void setValueAt(Object value, int rowIndex, int columnIndex) { data[rowIndex][columnIndex] = value; fireTableCellUpdated(rowIndex, columnIndex); } public MyTableModelTwo(String[] columnNames, Object[][] data) { this.columnNames = columnNames; this.data = data; }}class MyTableTwo extends JPanel implements TableModelListener { private static final long serialVersionUID = 1L; private JTable table; private Object[][] data; private JTextField t; public MyTableTwo(int noElements, String[] columnNames) { data = new Object[noElements][columnNames.length]; t = new JTextField(); MyTableModelTwo m = new MyTableModelTwo(columnNames, data); table = new JTable(m); table.getModel().addTableModelListener(this); setLayout(new GridLayout(1, 0)); JScrollPane scrollPane = new JScrollPane(table); add(scrollPane); } @Override public void tableChanged(TableModelEvent e) { } public JTextField returnT6() { return t; }} 解决方案 overide public Class getColumnClass(int column) {...please my question, why do you needed there AbstractModel, for why reasons, really what do you want to restict/mofify/change/override, ( you can prety ignore this == be sure that not really not good way to start to playing with anything for JTable based on AbstractTableModel ), however ... consider using DefalutTableModel rather than AbstractTableModel 这篇关于设置JTable中列的数据类型的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
