How can I create a Java method that accepts a variable number of arguments?

Question

For example, Java\'s own String.format() supports a variable number of arguments.

String.format(\"Hello %s! ABC %d!\", \"World\", 123);
//=>

Take a look at the Java guide on varargs.

You can create a method as shown below. Simply call System.out.printf instead of System.out.println(String.format(....

public static void print(String format, Object... args) {
    System.out.printf(format, args);
}

Alternatively, you can just use a static import if you want to type as little as possible. Then you don't have to create your own method:

import static java.lang.System.out;

out.printf("Numer of apples: %d", 10);
