Answer:
The advantage for the above condition is as follows:-
Explanation:
- If a user creates a defined constant variable and assigns a value on its and then uses that variable instead of the value, then it will a great advantage.
- It is because when there is a needs to change the value of that variable, then it can be done when the user changes the value in one place. There is no needs to change the vale in multiple places.
- But if there is a value in multiple places instead of a variable and there is no constant variable, then the user needs to change the value in multiple places.
Answer:
802.11a
Explanation:
802.11a supports bandwidth of 54 Mbps in a regulated frequency spectrum of 5 GHz. 802.11a also referred to as Wi-fi 2. 802.11a is basically costs higher than 802.11b though both were created at the same time. Hence 802.11b is more popular than 802.11a . All of them are developed by IEEE.

Complete Question:
The method shown below,
public void makeJunk()
{
new File("junk").createNewFile();
}
generates compile-time error:
"unreported exception java.io.IOException; must be caught or declared to be thrown".
Without changing the behavior (any part of the method body) and without changing the number of arguments the function takes or its visibility, add the necessary code that will permit this code to compile without error.
Answer:
public void makeJunk() throws IOException {
new File("junk").createNewFile();
}
Explanation:
In Order to gain a better understanding of this answer let first explain some terms.
Exception:
An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. When an error occurs within a method, the method creates an object and hands it off to the run-time system.The object, called an exception object, contains information about the error, including its type and the state of the program when the error occurred. Creating an exception object and handing it to the run-time system is called throwing an exception.After a method throws an exception, the run-time system attempts to find something to handle it. The set of possible "somethings" to handle the exception is the ordered list of methods that had been called to get to the method where the error occurred
java.io.IOException:
This exception is related to Input and Output operations in the Java code. This exception happens when there is a failure during reading, writing and searching file or directory operations.
The Compile- time error "unreported exception java.io.IOException; must be caught or declared to be thrown", means that the exception that would handle any errors that occurred during creating of the new file was not thrown in the first code so in order to solve the problem Without changing the behavior(any part of the method body) The exception that would handle that error was added to the solution code.
