@SafeVarargs annotation for private methods in Java 9?
The @SafeVarargs annotation was introduced in Java 7. This annotation applies to both final and static methods or constructors that take varargs parameters. This annotation used to make sure that a method does not perform unsafe operations on its varargs parameters. Since Java 9, @SafeVarargs annotation also applies to private instance methods.
Syntax
@SafeVarargs
private void methodName(...) {
// some statements
}Example
import java.util.ArrayList;
import java.util.List;
public class SafevarargsTest {
@SafeVarargs // Apply @SafeVarargs to private methods
private void display(List<String>... names) {
for(List<String> name : names) {
System.out.println(name);
}
}
public static void main(String args[]) {
SafevarargsTest test = new SafevarargsTest();
List<String> list = new ArrayList<String>();
list.add("TutorialsPoint");
list.add("Tutorix");
test.display(list);
}
}Output
[TutorialsPoint, Tutorix]
