Long [] number; //Common definition methods can be divided into static and dynamic definition methods, which are explained below.

Long number []; //Usage is the same as above.

Long ... numbers; //can only be used to define parameters in a function.

[] Long numbers; //definition error, there is no such writing.

Static definition:

int[] numbers = { 1，2，3，4，5 }；

Dynamic definition:

int size = 5；

int[]numbers = new int[size]；

for(int I = 0； I< size; i++) {

Number [I] = I+1;

}

Definition of formal parameters of int ... xx:

Public void testArray(int ... number) {

for (int i : numbers) {

//Print all elements of the passed parameter.

system . out . println(I)；

}

}
