Question

关于 format 提示：类型 String 中的方法 format（String, Object[]）对于参数（String, String）不适用

//TextFieldFrame类
package text;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.*;
import javax.swing.*;

public class TextFieldFrame extends JFrame{

private JTextField textField1;
private JTextField textField2;
private JTextField textField3;
private JPasswordField passwordField;

public TextFieldFrame()
{
super("Texting JTextField and JPasswordField");
setLayout(new FlowLayout());

textField1=new JTextField(10);
add(textField1);

textField2=new JTextField("Enter text here");
add(textField2);

textField3=new JTextField("Uneditable text field",21);
add(textField3);

passwordField=new JPasswordField("Hidden text");
add(passwordField);

TextFieldHandler handler=new TextFieldHandler();
textField1.addActionListener((ActionListener) handler);
textField2.addActionListener(handler);
textField3.addActionListener(handler);
passwordField.addActionListener(handler);
}

private class TextFieldHandler implements ActionListener
{

public void actionPerformed(ActionEvent event) {
// TODO 自动生成方法存根
String string="";
if(event.getSource()==textField1)
{
string=String.format("textField1:%s", event.getActionCommand());
}
else if(event.getSource()==textField2)
{
string=String.format("textField2:%s", event.getActionCommand());
}
else if(event.getSource()==textField3)
{
string=String.format("textField3:%s", event.getActionCommand());
}
else if(event.getSource()==passwordField)
{
string = String.format( "passwordField: %s",
new String( passwordField.getPassword() ) );
}
JOptionPane.showMessageDialog(null, string);
}

}
}

//TextFieldTest类
package text;
import javax.swing.*;
public class TextFieldTest {

/**
* @param args
*/
public static void main(String[] args) {
// TODO 自动生成方法存根

TextFieldFrame textFieldFrame=new TextFieldFrame();
textFieldFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
textFieldFrame.setSize(350, 100);
textFieldFrame.setVisible(true);
}

}

请各位帮帮忙 看看如何修改才能正确执行？ 谢谢啦

Answer 1

我也遇到了，刚解决，加载下JavaSE 1.5以上的环境就行了，如果用Myeclipse编译的话，右键点项目，属性，构建路径，库中添加库，找到JavaSE 1.6，加载下就行了
