How to show variable "a" into zona textfield in android studio

Answer 1

You need to define a outside of the switch statement, and then set it inside. For example:

String a = "";
switch (name){
    case "Rusia":
        a = "Tuan Rumah";
        break;
    case "Brazil":
        a = "Zona Concacaf";
        break;
    default:
        a = "Unknown";
}
zona.setText(a);

Answer 2

Define it out the switch block:

    String a = "default";
    switch (name){
        case "Rusia":
            a="Tuan Rumah"
            break;
        case "Brazil":
            a="Zona Concacaf"
            break;
    }
    zona.setText(a);

Answer 3

String a = "";
switch (name){
    case "Rusia":
        a = "Tuan Rumah";
        break;
    case "Brazil":

        break;
