private void btnAddActionPerformed(java.awt.event.ActionEvent evt) {
try {
int x = JOptionPane.showConfirmDialog(null,
"Do You Want to add this Record?");
if (x == 0) {
Connection c = DBconnect.connect();
Statement s = (Statement) c.createStatement();
s.executeUpdate("INSERT into employee VALUES('"

} catch (Exception e) {
e.printStackTrace();

You can use isSelected() and getValue() methods of JRadioButton.
您可以使用 JRadioButton 的 isSelected() 和 getValue() 方法。
if(rdbGenderM.isSelected())
gender="Male";
else if(rdbGenderF.isSelected())
gender="Female";
Assuming gender has been selected,
假设已选择性别，
s.executeUpdate("INSERT into employee VALUES('"
+ txtEmpId.getText() + "','" + txtName.getText() + "','" + gender + "')");

Use characters. If male was selected, insert M in DB, else F
使用字符。如果选择了男性，则在 DB 中插入 M，否则为 F
