import java.awt.Color;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.WindowConstants;
import javax.swing.text.DefaultCaret;

public class Main {
  public static void main(String args[]) {
    JTextArea textArea = new JTextArea();
    
    JFrame f = new JFrame();
    f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    DefaultCaret caret = new DefaultCaret() {
      @Override
      public boolean isSelectionVisible() {
        return true;
      }
    };
    textArea.setCaret(caret);
    textArea.setFont(new java.awt.Font("Miriam Fixed", 0, 13));
    
    Color color = Color.BLUE;
    // textArea.setBackground(color);
    textArea.setSelectedTextColor(color);
    f.getContentPane().add(new JScrollPane(textArea));
    f.pack();
    f.setVisible(true);
  }
}
