Answer:
David can apply filter to the data in order to show only records that meet the criteria.
Explanation:
- Filter is a very helpful option that displays the records that you want to view, hiding rest of the unwanted records.
- Sometimes you want to extract and view only the records that match a specific criteria instead of viewing all the records.
- For example in the CUSTOMERS table which contains names, addresses, countries of customers. There are several customers from different countries but you only want to view the customers from Spain. So you can use filter feature to view all the customers from country Spain.
- In MS Access you can apply filters using Sort & Filter group in the Home tab by selecting the desired column. In SQL, WHERE clause can be used along with SELECT to for filtering and extracting certain records. SELECT will select the records from the table and WHERE clause will specify the criteria to select the certain records.
Answer:
Let our mask be 1010000...000. Notice that, if we apply XOR operation to any number with this mask, the first and third bits will be complemented and all other bits will be unchanged. Since for each individual bit, XOR with 0 does not change the value of bit and XOR with 1 changes the value of bit.
Explanation:
To give a hexadecimal number, we should know the number of bits in representation of number.

found this on a website hope you find it useful !
Here is my solution. I did the following:
- changed the setRemover into a constructor, since the comment seems to hint that that is expected.
- changed the lookFor type into a String, so that it can work with the string replace overload. That's convenient if you want to replace with an emtpy string. The char type won't let you do that, you can then only replace one char with another.
- Added a static Main routine to use the class.
import java.lang.System.*;
public class LetterRemover
{
private String sentence;
private String lookFor;
public LetterRemover() {}
// Constructor
public LetterRemover(String s, char rem)
{
sentence = s;
lookFor = String.valueOf(rem);
}
public String removeLetters()
{
String cleaned = sentence.replace(lookFor, "");
return cleaned;
}
public String toString()
{
return sentence + " - letter to remove " + lookFor;
}
public static void main(String[] args)
{
LetterRemover lr = new LetterRemover("This is the tester line.", 'e');
System.out.println(lr.toString());
String result = lr.removeLetters();
System.out.println("Resulting string: "+result);
}
}
Demographics are different groups of people you would want to appeal to. Ex. Women, Americans, Mexicans, Men, and Children.
And as always have a wonderful day user!
