From JavaDoc

public void remove(int index)

    Removes the component, specified by index, from this container. This method also notifies the layout manager to remove the component from this container's layout via the removeLayoutComponent method.

    Parameters:
        index - the index of the component to be removed

But as mentioned in above answers you need to do 

jComboBox1.removeItemAt(jComboBox1.getSelectedIndex());

Hope it helps

There is no such method remove in Class JComboBox.

You want to use public void removeItemAt(int anIndex):

Removes the item at anIndex This method works only if the JComboBox uses a mutable data model.

jComboBox1.removeItemAt(jComboBox1.getSelectedIndex());

It looks like you want jComboBox1.removeItemAt(...)

see http://docs.oracle.com/javase/7/docs/api/javax/swing/JComboBox.html#removeItemAt(int)
