Question

Ola,

Android/JAVA question, I need to test if a object is not NULL and if it’s not NULL check a value, thus avoiding runtime error. As my vb.net background I’m used to;


if (not BackgroundWorker1 = nothing) andalso (backgroundworker.status = running) then


Is there a charming, ‘one IF’/single line way to do this in JAVA?

Thanks!

Answer 1

There’s a pretty direct translation:

if (BackgroundWorker1 != null && Backgroundworker1.status == running)
{
    // "then" part here
}

Just like VB’s andalso operator, Java also uses short-circuit evaluation with its logical operators.
