adressing vars

hi all.
this is really basic stuff i'm sure but i cant seem do adress variabes dynamicallly, like i used to do in acionscript. example:
background("maxvar_"+1,maxvar_2,maxvar_3);
or
background(int("maxvar_"+1),maxvar_2,maxvar_3);
or anything else i tried.
another example:
for (int c=0;c<num;c++) {
y= "maxvar_"+c;
}
making an array is not really an option because the vars have to be declared publicly(maxlink) and if i put them in an array like "public float myarray[] = {maxvar_1,.....} it doesnt work.
so i'm sorry if this is really simple but i'm stuck.
thx a lot in advance.

you can't create the name for a variable dynamically in Java, like you can in javascript and actionscript.
I'm not quite sure why you say an array wouldn't work.
Code:
//outside of setup, loop etc..
float[] myarray;
//in setup()
myarray=new float[3];
myarray[0]=maxvar_1;
myarray[1]=maxvar_2;
myarray[2]=maxvar_3;

that should create the array, and populate it,and have it available to all your code.
Then you'll be able to do:
Code:
background(myarray[0],myarray[1],myarray[2]);
//and
for(int i=0;i<myarray.length;i++)
{
y=myarray[i];
}
