Optimization for: while (true)

Question

I'm using a

while (true)
{
    if (x == y)
    {
        break;
    }
    else
    {
        //do stuff
    }
}

loop like so, the frame is just an example frame, as the actual code itself is convoluted and overly complicated that it requires a "break;" statement in multiple different areas for multiple different conditions. My question is; Is there a way to write a loop statement without the loop checking for a condition at all? Is there a more efficient way to write an infinite loop other than while(true)?

edit: (java)

edit2:

while (a < b)
{
    while (true)
    {
        if (c < d)
        {
            if (e == null)
            {
                //do alot of stuff
                break;
            }
            else
            {
                //do something
            }
        }
        else if (d > c)
        {
            if (e == null)
            {
                //do alot of stuff
                break;
            }
            else
            {
                //do something
            }
        }
        else if (d == c)
        {
            break;
        }
    }
    a = a + 1;
}

You can write an infinite loop in multiple ways, but they are all equivalent. Neither is really more efficient than the others:

1. while (true) { ... }
2. do { ... } while (true);
3. for (;;) { ... }

Depending on the actual code, it may make sense to reverse the "break-loop-logic" into "continue-loop-logic", as in:

boolean continueLoop;
do {
    continueLoop = false;

    // ... do stuff ...

    if ( some condition ) {
        continueLoop = true;
    }

    // ... do stuff ...

} while (continueLoop);
