public static int fiveOfaKind(int dice[]){
Obviously it is declaring a method but what I'm confused about is the part that goes "(int dice[])"
dice is an integer array that was declared in the main method.
What does that bit in the parenthesis do? And what is it called, I want to look it up and read about it.
What does that bit in the parenthesis do?
It requires that it is an array of variable length.
what is it called
Square brackets
Hope that helps...
It's a parameter for the method. The dice array declared in the main method is in a different scope and unrelated to this method.
public static void printArr(int arr[]) {
for(int i = 0; i < arr.length; i++){
System.out.println(arr[i]);
}
}
public static void main(String args[]) {
int[] dice = new int[5];
...
foo(dice);
}
In this example you have a method that takes an array and prints the elements in it. In the main method you pass this array to the method as a parameter.
