给出一个字符串,例如:
RT @John: Hello world! @Peter Hello!
我希望能够在RT @'之间获得分数。和':'。我怎样才能在PostgreSQL中实现这个目标?
答案 0 :(得分:0)
也许一个简单的SUBSTRING可以解决您的问题:
import javax.swing.JFrame;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.JLabel;
import javax.swing.Icon;
import javax.swing.ImageIcon;
public class ExecuteMe extends JFrame {
private static final long serialVersionUID = 1L;
public static void main(String[] args) throws MalformedURLException {
URL url = new URL("http://gph.is/291u1MC");
Icon icon = new ImageIcon(url);
JLabel label = new JLabel(icon);
JFrame f = new JFrame("Animation");
f.getContentPane().add(label);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
}
