Method x1() must either catch IOException or declare that it, too, throws IOException or a superclass of IOException.

Answer: Option 3.

<u>Explanation:</u>

IOException is a special case which developers use in the code to toss a disappointment in Input and Output activities. It is a checked exemption. The software engineer needs to subclass the IOException and should toss the IOException subclass dependent on the specific circumstance.

It can toss an IOException when the either the stream itself is adulterated or some mistake happened during perusing the information for example Security Exceptions, Permission Denied and so on as well as a lot of Exceptions which are gotten from IOException .

yawa3891 [41]

Answer:

4 is the correct answer for the above question.

Explanation:

  • If the if-else sequence has 4 blocks then it will be designed like if, else-if, else-if and then else which made 4 blocks which are as follows:-
  1. The first block is an if block.
  2. Then the second block is an else-if block.
  3. The third block is also else-if block and
  4. The fourth block else blocks.
  • So there is a need of 4 value (one value for each case) to test the application which is defined in the above scenario.
  • It is because when the first if statement is false then the first else-if statement is executed and when the first else statement is false then the second else-if statement is executed and when it is false then the else statement will executed.

When defining a class, it is a best practice to declare ____ as private. constructors mutators nothing should be private accesso
katrin [286]

Answer:

The answer is "variables".

Explanation:

It is necessary to declare a variable privately when declaring a class because the private variable 'protects' the code while it is in operation. It may not aim to protect it at this stage from changing the codes themselves for other developers. Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.
