怎么获取radiobutton和jcombobox中的值

java吗？举例如下：
String StudentGender; //性别

JRadioButton Gender_Male = new JRadioButton("男<male>",true);
JRadioButton Gender_Female = new JRadioButton("女<female>");
//获取性别类型
if(Gender_Male.isSelected())
{
StudentGender = Gender_Male.getText();
}
else
{
StudentGender = Gender_Female.getText();
}

2. JComboBox comboDepartment = new JComboBox(); //学院
comboDepartment.addItem("计算机科学学院");
comboDepartment.addItem("数学与软件科学学院");
comboDepartment.addItem("化学与材料科学学院");
comboDepartment.addItem("文学与历史文化学院");
comboDepartment.addItem("物理与电子工程学院");
comboDepartment.addItem("地理与环境科学学院");
comboDepartment.addItem("艺术与体育学院");
