The other answers misunderstand the question (or they don't know what select is in Go).

Go does have a switch and a select statement, where the switch is the rough equivalent of Java's switch, and the select statement is similar to switch but only to select on communication operations (the cases are comm. ops.: a send statement or a receive operation).

Java does not have an equivalent to Go's select. You can achieve the same but in a more verbose way, and it's not built into the language like Go's select.

The similar syntax in Java is switch. For detail, you could refer to https://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html.

switch (month) {
    case 1:  monthString = "January";
             break;
    case 2:  monthString = "February";
             break;
    default: monthString = "Invalid month";
             break;

}
