| Use the standard template Java source files. Replace the asterisks by appropriate text. Provide your name, the assignment number, the name of the file and the number of columns between tab stops that you have used. |
Do not start your file with
package packname;If you do, then I have to remove that line in order to run your program. (With that line in, I would have to be sure that your program is in a directory called packname, or even in a specific subdirectory of another specific directory if the package name has a dot in it. That makes my job more time consuming.) |
|
If you use tabs, you must say, in the heading at the top of the file,
where the tab stops are. For example, if your tab stops set every
4 spaces, say so.
Pay attention to this! If you specify the wrong spacing of tab stops, your program might be very poorly indented, and you will lose points for indentation. |
| Do not write lines longer than about 80 characters. Break long lines. |
Use blank lines [USE-BLANK-LINES: 1-2 points]

Every component of a structured statement (if-statemet,
while-statement, do-statement, for-statement, switch-statement)
must be surrounded by braces and indented either 2 or 3 spaces,
as shown in the following example. A right-brace must be directly
below the matching left-brace.
if(condition)
{
statement
…
statement
}
else
{
statement
…
statement
}
Exception. If the component is and empty set of braces {}, then it is not required to be on separate lines. For example, you are allowed to write
for(…) {}
where the empty set of braces is the for-loop body.
*A program that has exceptionally poor indentation throughout can lose up to 40 points for lack of indentation. |
When several if-statements are used to simulate multiple cases,
indent all of the cases the same amount, as in the
following example.
if(condition)
{
statements
}
else if(condition)
{
statements
}
else if(condition)
{
statements
}
else
{
statements
}

No incorrect indentation for sequencing [INDENT-SEQUENCE: 1-10 points*]
Two statements that are performed one after another
must be indented the same amount. For example,
int x;
int y;
is not correctly indented. Similarly,
int badindentdemo(int n)
{
for(int i = 0; i < n; i++)
{
if(test(i))
{
return i;
}
}
return -1;
}
is not correctly indented. Since statement
return −1 is performed just after
the for-loop (assuming that the return statement
inside the for-loop is not done),
it should be indented the same amount as the word for.
