Question

I’m wondering how I do the following. Make 10 int variables called, var_0, var_1, var_2, etc.
All holding 0. I’m picturing something like this…

for(int i=0;i>10;i++){
   int var_i = 0;
}

But of course it doesn’t work. How do I make this work without doing every single variable manually?

It’s intended for an arbitrary amount of variables.

Answer 1

It’s impossible in Java, there are no macros that would let you do it. Usually if you need 10 variables with same name you just use array.

int vars[] = new vars[10];

It will be initialized to zeroes by default.

If you don’t know number of elements in advance you can declare array and construct it later:

int vars[];
...
int numVars = 10;
vars = new int[numVars];
