JSF

<h:selectManyCheckbox value="#{myBean.values}">
    <f:selectItem itemValue="1" itemLabel="Value - 1" />
    <f:selectItem itemValue="2" itemLabel="Value - 2" />
    <f:selectItem itemValue="3" itemLabel="Value - 3" />
</h:selectManyCheckbox>

Bean

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

@ManagedBean(name="myBean")
@RequestScoped
public class MyBean{

    public String[] values;

        //getters setters

}

Update:

To print array values as mentioned in the example, you can have following util method 

   public String getFavNumber3InString() {
    return Arrays.toString(favNumber3);
}
