}

private void save() {

String str="";
str = name.getText().trim();
str = "男";

str = home.getSelectedItem().toString();
str = Others.getText().trim();

if(Woman.isSelected()){
str ="女";
}

JOptionPane.showMessageDialog(null, "确定");

}
}

当点击确定后，怎样将确定以上的内容显示到下面一个文本域里面？？？？？
初学.....

[解决办法]
差不多就这个意思

Java code

private void save() {        // TODO Auto-generated method stub        String str = "";        str = name.getText().trim();        str = "男";        str = home.getSelectedItem().toString();        str = Others.getText().trim();        if (Woman.isSelected()) {            str = "女";        }        JOptionPane.showMessageDialog(null, "确定");        textArea2.setText("姓名  "+name.getText()+"\n性别  "+"\n"+str+"\n"+textArea1.getText());//加上这句     }
