how to get input form combobox java

To get the input from a combo box in Java, you can use the getSelectedItem() method of the JComboBox class. This method returns the selected item in the combo box as an object, which you can then cast to the appropriate type.

Here's an example of how you can get the input from a combo box in Java:

import javax.swing.JComboBox;

// ...

JComboBox<String> comboBox = new JComboBox<>();
comboBox.addItem("Option 1");
comboBox.addItem("Option 2");
comboBox.addItem("Option 3");

String selectedOption = (String) comboBox.getSelectedItem();

In this example, the comboBox object represents a combo box component, and the selectedOption variable holds the selected option as a string.

It's important to note that the getSelectedItem() method returns null if no item is selected. You should handle this case appropriately in your code.
