In Java:
Write a program that prompts the user to enter a positive number until the user input a negative number. In the end, the program outputs the sum of all the positive numbers.
You should use do-while loop (not while, not for). You cannot use break or if statement in the lab.
Hint: if the program adds the last negative number to your sum, you can subtract the last number from the sum after the loop.

Changes in the economy have determined that for the EZ shipping company, a surcharge will be assessed on all packages that meet certain criteria. The surcharge is a function of the characteristics of the package and the zip code to which it is sent.
1. The regular charges for shipping are calculated as
follows:
For all weights five pounds and under, the
shipping cost is $12.00.
For weights over five pounds, the charge
is calculated as follows:
If length * width * height + weight is:
greater than 5 and less than or equal to 15, the shipping cost is 14.00
greater than 15 and less than or equal to 34, the shipping cost is 17.00
greater than 34 and less than or equal to 45, the shipping cost is 21.00
greater than 45 and less than or equal to 60, the shipping cost is 33.00
greater than 60, the shipping cost is 105.00
2. The additional charges are calculated as follows:
If the first digit of the zip code is a "4" then there is an additional surcharge of 5% on the shipping cost.
If the first digit of the zip code is a "6" then there is an additional surcharge of 9% on the shipping cost.
For all other zip codes there is an additional surcharge of 14% on the shipping cost.
3. Finally, if the zip code is even, then there is an additional surcharge of 2% of the shipping
cost.
Write a program that allows the user to input (in this order) the zip code, weight, length, width and height of the package then prints out the following:
The zip code and dimensions of the package
The shipping cost
The surcharge
The total shipping cost (shipping cost plus surcharge(s))
I have written out the code and have been able to get it to run but when I added in the 2% for even numbers portion of my code every thing went weird with my outputs. Every thing still compiles and works but I am not recieving the outputs I desire. Any help remedying this would be greatly appreciated.

1. Consider the loop from Section 8.3 of your textbook.
prefixes = 'JKLMNOPQ'
suffix = 'ack'
for letter in prefixes:
print(letter + suffix)
Put this code into a Python script and run it. Notice that it prints the names "Oack" and "Qack".
Modify the program so that it prints "Ouack" and "Quack" but leaves the other names the same.
Include the modified Python code and the output in your submission.
2. Give at least three examples that show different features of string slices. Describe the feature illustrated by each example. Invent your own examples. Do not copy them for the textbook .

Similar to in HW1, you'll implement a left shift of decimals in a string, with combining of multiple like digits into a single digit of double the value. The main difference between HW1 and this is that now the string representing a row in 2048 can be of any length! You'll implement a Combine class in a comparable .java file.
As before, the input string can only include the characters '_', '2', and '4'. Unlike before, it can be of any length (including length 0). Any '2's that have no other characters or any number of '_'s between them combine to become a '4'(i.e. two '2's disappear, and a '4' is left in one of their space). Likewise, '4's become '8's. Any digit that is the result of a combination cannot be combined with another digit. All digits are combined in this way and shifted to the far left so that any '_' appear on the right of the string. The length of the string remains unchanged.
Your classes will implement the Combinable interface. Note that we're attaching an updated version so be sure to use the new one. You will implement multiple methods from the interface Combinable:
The requirements remain unchanged from HW1.
The string must include only the characters discussed above, but it can be of any length. Return true if it includes only valid characters, false otherwise. You must invoke validateChar to determine validity of each character.
Create a string that consists of num, ch characters.
Given a String s, return a new String that has all '_' characters removed. You cannot use the replace method in the String Class. Note that the returned string will be of the same or lesser length than the argument.
All non-'_' characters in the input string are shifted to the left of the string, leaving only '_'s on the right-hand side of the string. The resulting "left-shifted" String is returned. It is highly suggested that you first use eliminateUnderscores to cluster all the non-'_' characters, and then to use repeat to concatenate the appropriate number of '_' on to the right of the String that is returned. Most other ways to implement this method are far more complicated.
You must invoke the validateRow method to test
if
the input String is valid. If it is not, return the input string
directly without change.
Given the input string, the output should be a string of the same length, with all '_'s removed from the left side of the string, and with all pairs of like digits with only '_'s in between them, combined into a digit of twice the value. Return the resulting String.
It is highly suggested that you use the moveLeft method to help you with this implementation. When generating your new string, it is much easier to be able to ignore all '_' between digits.
You must invoke the validateRow method to test if the input String is valid. If it is not, return the input string directly without change.
Some example assertions:
assert validateChar('_'); assert !validateChar(' '); assert validateRow("2222"); assert validateRow("_24_"); assert !validateRow("2234_"); assert validateRow(""); assert !validateRow("*"); assert "***".equals(repeat('*', 3)); assert "".equals(repeat('*', 0)); assert "44444444".equals(repeat('4', 8)); assert "4".equals(eliminateUnderscores("__4__")); assert "244".equals(eliminateUnderscores("2_4_4_")); assert "".equals(eliminateUnderscores("___")); assert "242442".equals(eliminateUnderscores("242442")); assert "4____".equals(moveLeft("__4__")); assert "244___".equals(moveLeft("2_4_4_")); assert "___".equals(moveLeft("___")); assert "_3_".equals(moveLeft("_3_")); assert "242442".equals(moveLeft("242442")); assert "484___".equals(combineLeft("224422")); assert "484________".equals(combineLeft("2_2_4_4_2_2")); assert "242424__".equals(combineLeft("242_42_4")); assert "828____".equals(combineLeft("__44244")); assert "".equals(combineLeft("")); assert "22344".equals(combineLeft("22344")); assert "88__________".equals(combineLeft(combineLeft("_2_22_222_4_")));
Here is the first code:
public class Combine implements Combinable {
public boolean validateChar(char ch)
{
//Write your Code Here
return true;
}
public boolean validateRow(String row)
{
//Write your Code Here
return true;
}
public String repeat(char ch, int num)
{
//Write your Code Here
return "";
}
public String eliminateUnderscores(String
row)
{
//Write your Code Here
return "";
}
public String moveLeft(String row)
{
//Write your Code Here
return "";
}
public String combineLeft(String row)
{
//Write your Code Here
return "";
}
public static void main(String[] args)
{
Combine CM=new Combine();
assert CM.validateChar('_');
assert !CM.validateChar(' ');
assert
CM.validateRow("2222");
assert
CM.validateRow("_24_");
assert
!CM.validateRow("2234_");
assert CM.validateRow("");
assert !CM.validateRow("*");
assert
"***".equals(CM.repeat('*', 3));
assert "".equals(CM.repeat('*',
0));
assert
"44444444".equals(CM.repeat('4', 8));
assert
"4".equals(CM.eliminateUnderscores("__4__"));
assert
"244".equals(CM.eliminateUnderscores("2_4_4_"));
assert
"".equals(CM.eliminateUnderscores("___"));
assert
"242442".equals(CM.eliminateUnderscores("242442"));
assert
"4____".equals(CM.moveLeft("__4__"));
assert
"244___".equals(CM.moveLeft("2_4_4_"));
assert
"___".equals(CM.moveLeft("___"));
assert
"_3_".equals(CM.moveLeft("_3_"));
assert
"242442".equals(CM.moveLeft("242442"));
assert
"484___".equals(CM.combineLeft("224422"));
assert
"484________".equals(CM.combineLeft("2_2_4_4_2_2"));
assert
"242424__".equals(CM.combineLeft("242_42_4"));
assert
"828____".equals(CM.combineLeft("__44244"));
assert
"".equals(CM.combineLeft(""));
assert
"22344".equals(CM.combineLeft("22344"));
assert "88__________".equals(CM.combineLeft(CM.combineLeft("_2_22_222_4_")));
System.out.println("All tests
passed.");
}
}
Here is the second code:
public interface Combinable {
//checking if the character is a valid character
public boolean validateChar(char ch);
//checking if a row contains the correct set of characters
public boolean validateRow(String row) ;
//Create a string that consists of num, ch characters.
public String repeat(char ch, int num) ;
//Removing the undescore from the row
public String eliminateUnderscores(String row) ;
//Shifting the numbers to the left if there is any open
spance
public String moveLeft(String row) ;
//Combining the equal numbers in the row 22_ > 4__
public String combineLeft(String row) ;
