Answer:
C)An error message is issued.
Explanation:
If we try to open a file for reading when that file does not exist, we will get an error message.
For example, in Java we will encounter a FileNotFoundException as in the code below:
try {
FileInputStream fis = new FileInputStream("myFile.txt");
DataInputStream dis = new DataInputStream(fis);
BufferedReader br = new BufferedReader(new InputStreamReader(dis));
String str = null;
while ((str = br.readLine()) != null) {
System.err.println(str);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
If the file myFile.txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.
The article helps explain what “engaged” is referring to is :
Allison Silvestri, the former principal of San Lorenzo High School east of San Francisco, implemented the tool three years ago. The results "were tremendous," she said. The students were paying more attention in class.
Explanation:
- San Lorenzo High School allows students to bring their smartphones to campus and even keep them on their person, but all students have to insert their phones into a locked pouch for the entirety of the school day.
- It has absolutely changed our entire school climate and culture, San Lorenzo High School Principal Allison Silvestri said.
- "Students talk to me in the halls now. They have to talk to each other. A substitute teacher noticed better posture because they’re not looking down at their phones in the hallways on the way to class.”
- San Francisco-based Yondr created the green pouches specifically to curb cell phone use.
- The concept is fairly simple: students place their phones in a pouch at the beginning of the school day, lock the pouch shut and only regain access to their phones at the end of the day when the school unlocks the pouches with special magnets.
I beleive anything to do with manage
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Max of series: ");
n = input.nextInt();
for(int i = 1; i<=n;i+=4){
System.out.print(i+" ");
}
}
}
Explanation:
This declares n as integer. n represents the maximum of the series
int n;
This prompts the user for maximum of the series
System.out.print("Max of series: ");
This gets user input for n
n = input.nextInt();
The following iteration prints from 1 to n, with an increment of 4
<em> for(int i = 1; i<=n;i+=4){</em>
<em> System.out.print(i+" ");</em>
<em>}</em>
The easiest way is to hit the Windows icon on your keyboard, look for the Settings app, and look for screen resolution in the search bar.
