Description Jiri Prox 2015-09-18 13:13:38 UTC 
When adding JComboBox into frame, the model by default contains Strings but the variable is generated as 

private javax.swing.JComboBox<String> jComboBox1;

so the line

jComboBox1.setModel(new javax.swing.DefaultComboBoxModel<>(new String[] { "Item 1", "Item 2", "Item 3", "Item 4" }));

is not correct (on jdk < 1.8)

Thanks for catching this. So we need to initialize comboboxes with String type.
