Question

This should be relatively straight forward however I’m being swamped in SQL information whenever I search for help with this.

Basically I have 3 classes and they each generate a number and I want to get the total number at the end. Is there a way to make a variable which all 3 classes can add to without generating a SQLite Database?

example

• Page1.java creates 5 -> adds to Total

• Page2.java creates 12 -> adds to Total

• Page3.java creates 10 -> adds to Total

• Page4.java opens total

Like I said, its likely a simple problem but SQLite is dominating my searches.

Hope you can help, Thanks.

You can use a static variable for that.
If you don’t care about encapsulation you could even use one single public static variable for this purpose.

Example:

private static int mCounter = 0;

public static void addToCounter(int i)
{
    mCounter += i;
}

public static int getCount()
{
    return mCounter;
}
