Variable number of arguments defined method: just add three consecutive (ie, "..." in the English sentence ellipsis) between a parameter "type" and "parameter name", "." you can make an argument and uncertain match.
The following example creates sumvarargs () method to count the value of all the numbers:

public class Main {
static int sumvarargs(int... intArrays){
int sum, i;
sum=0;
for(i=0; i< intArrays.length; i++) {
sum += intArrays[i];
}
return(sum);
}
public static void main(String args[]){
int sum=0;
sum = sumvarargs(new int[]{10,12,33});
System.out.println("数字相加之和为: " + sum);
}
}
The above code is run output is:
数字相加之和为: 55
