What does "..." mean in java

Explanation:

Variable length parameter means that any number of parameters of this type can be passed in at this position. Simply put, it is an array.

If it appears in a formal parameter, it means a variable parameter, which means that the number of parameters passed in is variable. How many parameters you pass will be placed in an array.

For example:

public static void dealArray(int...intArray) {
    for(int i: intArray)
    {
        System.out.print(i +" ");
    }
    System.out.println();
}
