How can I add an item at the end of the array? The most easy way (arr [5]=8) returns "out of range", and I suppose it's because first I instantiate it as "int [] arr=new int[5]", so it's out of the range. Can I amplify that range?

I wonder. Since we don't need to declare a variable, does this mean that a variable which first I assign a numeric value can be assigned later with, for example, string value?
