Answer: i just learned something new.
Explanation:
Hello there.
<span>What happens when a filter is applied to a database?

As you consider your options, here are seven things you should know about a company before you decide to invest:
Earnings Growth. Check the net gain in income that a company has over time. ...
Stability. ...
Relative Strength in Industry. ...
Debt-to-Equity Ratio. ...
Price-to-Earnings Ratio. ...
Management. ...
Dividends.
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);
}
}
