private javax.swing.JButton jButton2;
private javax.swing.JButton jButton3;
private javax.swing.JPanel jPanel1;
private javax.swing.JScrollPane jScrollPane1;
private javax.swing.JTable jTable1;
`private javax.swing.JTextField jTextField1;
private javax.swing.JTextField jTextField2;`
// End of variables declaration
