Java conditional checks and assignment

Question

I am looking for a more efficient way to perform the following action, where I am appending the return value of a method to an array. However if the return is null i want to perform another action and not change the array.

Object[] myVal = new Object[10];
Object temp;
temp = myFunction();
if(temp != null) {
    myVal[count++] = temp;
} else {
    System.Exit();
}

Where I want to assign a variable to the return of a method, but provide an 'inline' check to carry out another action if the value returned is null.

Something like:

myVal = (myFunction() != null) ? [output of expression]: System.Exit();

Is there any method like this?

Answer 1

myVal = myFunction();
if (myVal == null) System.exit(0);

No need for a temp variable.

Answer 2

Try this:

if ((myVal = myFunction()) == null) System.exit(0);
else // do your work

Note: Usage of ternary operators is not recommended because code becomes hard to read.
