Compile Error:

stdout, stderr, and Error Code

For the line with the command rm -rf student-submission:
- There is no standard output as it just removes the folder named student-submission and its contents.
- There is no standard error as there is always a file named student-submission to remove.
- Since the command succeded, the return code would be 0.
For the line with the command git clone $1 student-submission:
- At first I thought the standard output would be the output of the git clone “Cloning into ‘student-submission’”. But when I used >out.txt to see the standard output, there was none, so this line does not contain any standart output.
- There is no standard error since the repository always exists and manages to get cloned.
- Since the command succeded, the return code would be 0
For the line with the command cd student-submission:
- There is no standard output as it just changes its working directory into student-submission
- There is no standard error as there is always a file named student-submission to change into
- Since the command succeded, the return code would be 0
For the line with the first if statment with [[ ! -f ListExamples.java ]] as a condition:
- There is no standard output as it just checks to see if a file doesn’t exits with ‘-f’
- There is no standard error as it will always find a file in student-submission
- Since the command succeded, the return code would be 0
For the line with the first if statment with [[ ! -e ListExamples.java ]] as a condition:
- There is no standard output as it just checks to see if it doesn’t finds a file with ‘-e’
- There is no standard error as it will always find a file in student-submission
- Since the command succeded, the return code would be 0
For the line with the command javac -cp ".;../lib/hamcrest-core-1.3.jar;../lib/junit-4.13.2.jar" *.java:
- There is no standard output as this commands makes the java classes in the folder student-submission
- There is no standard error as the java program always makes a class file
- Since the command succeded, the return code would be 0
For the line with the command java -cp ".;../lib/junit-4.13.2.jar;../lib/hamcrest-core-1.3.jar" org.junit.runner.JUnitCore ListExamples:
- There is no standard output as the command detecs an error, so it couldn’t go through with the command
- The standard error is:
```
 ListExamples.java:15: error: ';' expected
  result.add(0, s)
                  ^
 1 error
```
  This is the case since the student forgot to add a semicolon, ending the command short to give a standard syntax error
- Since the command failed and returned an error, the return code would be non-zero number. After some research, I think it would end up giving a error code of 1.

if Statments

There are two if statments in this bash script. One with the condition containing -f and one with -e. Both of these if statments are return false, since there will always be a file after the clone.
Since these if statments always return false, it will skip over the lines with the commands:
```
  echo "File does not exist"
  exit N
```
These commands do not run because they are in an if statment that returned false
