// I have the following code :

..............................

boxCon =Box.createHorizontalBox();

ta1 = new JTextArea("I am hammer,\nShe is Kelly!",10,15) ;

ta1.setLineWrap(true );

JScrollPane scroll = new JScrollPane (ta1);

scroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);

boxCon.add(ta1);

boxCon.add(scroll);

con= this.getContentPane();

con.setLayout(new FlowLayout());
