Q:

What is the output after compile and run the following code ?

int Output = 10;
boolean b = false;
if((b == true) && ((Output += 10) == 20))
{
System.out.println("We are equal " + Output);
}
else
{
System.out.println("Not equal! " + Output);
}

A) Compilation and output of "We are equal 10" B) Compilation and output of "Not equal! 10"
C) Compilation error, attempting to perform binary comparison on logical data type D) Compilation and output of "Not equal! 20"
 
Answer & Explanation Answer: B) Compilation and output of "Not equal! 10"

Explanation:

The output will be "Not equal! 10". Please note that && is logical AND operator. If first operand before (&&) is false then the other operand will not be evaluated. This illustrates that the Output +=10 calculation was never performed because processing stopped after the first operand was evaluated to be false. If you change the value of b1 to true, processing occurs as you would expect and the output would be "We are equal 20".

Q:

Lightning heats the surrounding air to

A) 300 deg Cent B) 3000 deg Cent
C) 30000 deg Cent D) 300000 deg Cent
 
Answer & Explanation Answer: C) 30000 deg Cent

Explanation:

Lightning is extremely hot — a flash can heat the air around it to temperatures five times hotter than the sun’s surface. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

Lightning heats the surrounding air to about 30,000 degrees Centigrades.
