This is a program I wrote in Python. You could use the same method to add without + in Java.. My solution (maybe not the desired solution, but the one I can up with) .. My solution was to for loop thru X and Y number of times, adding a number to an array each time.. the sum of X + Y becomes the length of the array.

For Example.. -
X=5
Y=3
EmptyArray=[]

for(int i=0; i<X; i++){
add I to EmptyArray
}

for(int i=0; i<Y; i++){
add I to EmptyArray
}

Sum = length(EmptyArray);

Answer 2

//this is probably cheating:

public class Program
{
public static void main(String[] args) {
System.out.print(5-(-5));//5+5
//outputs 10
}
}
