I copied some text from www.mainichi.co.jp into Libre Office. I saved
the text as UTF-8. I used the program below to display it. It isn't
quite correct though, I get a dot before the text that wasn't on the web
page. Other than that it works fine.
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.nio.charset.*;
import javax.swing.*;
public class test extends JPanel {
private char[] buffer = new char[256];
private int n;
public test() {
setPreferredSize(new Dimension(320,240));
try {
FileInputStream fis = new FileInputStream("xxx");
InputStreamReader isr = new InputStreamReader(fis,"UTF-8");
n = isr.read(buffer,0,256);
isr.close();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
public void paintComponent(Graphics g) {
g.setFont(new Font("MS Mincho",Font.PLAIN,12));
g.drawChars(buffer,0,n,10,20);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.add(new test(),BorderLayout.CENTER);
f.pack();
f.setVisible(true);
}
});
}
}
