Answer:
The output of the given code as follows:
<u>Output:
</u>
1122
Explanation:
In the given java code the two for loop is defined, which can be described as follows:
- In the first loop, a"loop" variable is used, which starts from 1 and ends when the value of loop is less than 3, inside the loop a print function is used, that print value 1.
- In the next step, another for loop is declared, inside the loop a variable "loop2" variable is used, that's working is the same as the above loop, but in this loop, it will print a value, that is 2.
Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.
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);
}
}
