JAVA中Main函數之注意

Problem?
Whats this syntax useful for :

    **function(String... args)**
Is this same as writing

    **function(String[] args)**
with difference only while invoking this method or is there any other feature involved with it ?











Answer 
The only difference between the two is the way you call the function. With String var args you can omit the array creation.

public static void main(String[] args) {
    callMe1(new String[] {"a", "b", "c"});
    callMe2("a", "b", "c");
    // You can also do this
    // callMe2(new String[] {"a", "b", "c"});
}
public static void callMe1(String[] args) {
    System.out.println(args.getClass() == String[].class);
    for (String s : args) {
        System.out.println(s);
    }
}
public static void callMe2(String... args) {
    System.out.println(args.getClass() == String[].class);
    for (String s : args) {
        System.out.println(s);
    }
}
