Answer:
Your program would run without error if you declared the first and second string variables before using them:
Modify the following:
first=input.nextLine();
second=input.nextLine();
to:
String first=input.nextLine();
String second=input.nextLine();
Explanation:
Required
Program to print two strings in forward and reversed order
<em>The program you added is correct. The only thing that needs to be done is variable declarations (because variables that are not declared cannot be used).</em>
<em></em>
So, you need to declared first and second as strings. This can be done as follows:
<u>(1) Only declaration</u>
String first, second;
<u>(2) Declaration and inputs</u>
String first=input.nextLine();
String second=input.nextLine();
Answer:
A.) Phase in degree= 40° ; phase in radian
B.) Bandwidth is the same.
Explanation:
1 complete cycle = 360°
Therefore, 1/9 of a cycle :
Phase in degree ;
(1/9) × 360° = 40°
Phase in radian:
40 × (2π/360)
80π/360
= 0.222πrad
0.698rad
In simple terms, A bandwidth could be explained as the difference between the upper and lower frequencies of the signal. However, the signal described above is a simple signal with no upper or lower frequency boundary.
hence, the bandwidth is assumed to be the same.
Answer:
HTTP is the application layer protocol required.
Explanation:
For a web page to be displayed on a browser, the seven layers of the OSI model work together. On the application layer, HTTP protocol is used to communicate between the server and the client. The HTTP client is the browser (Chrome, Internet Explorer, Firefox etc.) which sends a request to the HTTP server for accessing a web page.
When a URL is accessed, the HTTP client sends a request to the HTTP server. The server locates the file which is being requested and sends a response message containing the web page which is to be displayed. The exchange of data between the HTTP client and server takes place over a TCP connection.
TCP is a transport layer protocol which provides a reliable connection over which the exchange of data takes place. Data at the transport layer is sent in the form of segments. If the data being sent from the server is too long, it is divided into multiple segments and sent one after the other. The client is then responsible for joining the segments and displaying the information as a web page. The transport layer is also responsible for error correction and detection during the communication process.
If the student is sending or retrieving information from a secure website, the messages being exchanged between the client and server will be encrypted. This means that if a third-party tries to tap the communication process, they would not be able to decipher the messages. This increases the security and helps keep the information present on the web page confidential.
Answer:
You should have a line on which you can add information below the <style> tag and above </style> tag. simply add the body tag after <style> tag.
Explanation:
From the below code you can understand it how you can change the background color of a section in html.
<!DOCTYPE html>
<html>
<head>
<style>
body {
background-color: #afafaf;
}
h {
background-color: #00b33c;
}
p {
background-color: #00d33c;
}
</style>
</head>
<body>
<h1>Header with green background</h1>
