我写了一个满足你的图片的要求，你看看，有什么问题百度hi我：
import java.awt.BorderLayout;

import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.border.TitledBorder;

public class TestDemo extends JFrame{
private static final long serialVersionUID = -5355432125621015300L;
private Option[] options = new Option[4];
public TestDemo () {
init();
}
private void init(){
setTitle("我的文本域");
setSize(300,200);
setContentPane(createContentPane());
}
private JPanel createContentPane(){
JPanel pane = new JPanel(new BorderLayout());

pane.add(BorderLayout.NORTH,createQuestionPane());
pane.add(BorderLayout.SOUTH,createOptionsPane());

return pane;
}
private JPanel createOptionsPane(){
JPanel pane = new JPanel();
Option a = new Option(0,"A");
Option b = new Option(1,"B");
Option c = new Option(2,"C");
Option d = new Option(3,"D");
options[0]=a;
options[1]=b;
options[2]=c;
options[3]=d;
pane.add(a);
pane.add(b);
pane.add(c);
pane.add(d);
return pane;
}
private JScrollPane createQuestionPane() {
JScrollPane pane = new JScrollPane();
pane.setBorder(new TitledBorder("题目"));
JTextArea questionArea = new JTextArea();
questionArea.setRows(6);
questionArea.setText("问题\nA.\nB.\nC.\nD.");
questionArea.setLineWrap(true);
questionArea.setEditable(false);
pane.getViewport().add(questionArea);
return pane;
}

class Option extends JCheckBox{
private static final long serialVersionUID = 5569918347028393191L;
int val;
public Option(int val, String txt) {
super(txt);
this.val = val;
}
}

public static void main(String[]args){
TestDemo td=new TestDemo();
td.setVisible(true);
}

}
