How to add three values together?

Question

Hi,
I'm working on a program which is supposed to be able to add three numbers together like this: (notice that the program asks for three numbers. these three numbers are the ones to be added up, see below)
Enter number one:
*5*
Enter number two:
*10*
Enter number three:
*15*
What i want the program to do is to add these three numbers together and print THE SUM (30) not the three numbers. This is how the code which I use to print out the values looks now:
System.out.println("the sum of the numbers is" + (num1) + (num2[i]) + (num3[i]) + "hours");
What the programs does is that instead of printing the sum (30), it prints: 51015 (thus, the typed numbers, side by side...).
What can i do to make the program print the sum of the three numbers and not the three numbers itself. Thanks in advance..

thx for the tip, still doesn't work though. This is how it looks:
First part, declaring variables:_
String aname;
         int i = 0;
         String[] name;
         name=new String[3];
         String[] aa;
              aa= new String[3];
              String[] ab;
              ab=new String [3];
              String [] ac;
              ac=new String[3]; and here is the second part where the program is supposed to print the sum of aa, ab and ac:
System.out.println(aname + " has totally " + ((aa)+(ab[i])+(ac[i])) + " hours");
Please let me know if there's any other part of the code you need.*
