You need to DECLARE first_param outside the if { ... } block, and SET it inside.

String sjcb_EM = jcb_EM.getSelectedItem().toString();

        String first_param = "";
        
        if (sjcb_EM == "Evey Minute"){
            
            first_param = "*";
        }
 
        System.out.println(first_param);

Solution 2

Declare it outside of the if statement. If you don't declare it outside of it, it will only be declared inside of the if statement and won't be able to be called on.
