Which line will cause a compilation error?
public class Sample06
{
private int limit;
private boolean capped;
void configure()
{
assert capped = true;
assert limit = 10;
}
public static void main(String[] args)
{
new Sample06().configure();
}
}
Answer: B
An assignment is an expression whose value is the value assigned, so this one has type int and fails the boolean requirement. The same shape with a boolean variable, assert flag = true;, does compile, which is what makes this worth knowing: the single = is not itself the error.
