Data Matrix 2d Barcode Generation In Java
Using Barcode encoder for Java Control to generate, create ECC200 image in Java applications.
In this case, the name conveyed the correct intent but the implementation was wrong; it's easy for a sensible name to disguise a broken implementation Here's an example in which the name and the code are in complete contradiction:

public boolean inTable(0bject obj) { i n t j = t h i s getIndex(obj) ; return (j == nTable);
Reading Barcode In Java
Using Barcode reader for Java Control to read, scan read, scan image in Java applications.
The function getIndex returns a value between zero and nTable-1 if it finds the object, and returns nTable if not The boolean value returned by i nTabl e is thus the opposite of what the name implies At the time the code is written, this might not cause trouble, but if the program is modified later, perhaps by a different programmer, the name is sure to confuse

Using Barcode decoder for Visual Studio .NET Control to read, scan read, scan image in .NET framework applications.
By analogy with choosing names to aid the reader's understanding, write expressions and statements in a way that makes their meaning as transparent as possible Write the clearest code that does the job Use spaces around operators to suggest grouping; more generally, format to help readability This is trivial but valuable, like keeping a neat desk so you can find things Unlike your desk, your programs are likely to be examined by others

Reformatting improves it somewhat:

Even better is to put the assignment in the body and separate the increment, so the loop takes a more conventional form and is thus easier to grasp: f o r (n++; n < 100; n++) field[n] = '\0'; *i = '\O1; return ' \ n ' ;

Use the natural form for expressions Write expressions as you might speak them aloud Conditional expressions that include negations are always hard to understand:
i f (! (block-id
a c t b l k s ) I I ! (block-id >= unblocks))
Each test is stated negatively though there is no need for either to be Turning the relations around lets us state the tests positively: i f ((block-id >= actblks) I I (blockkid < unblocks))
Now the code reads naturally
Parenthesize to resolve ambiguity Parentheses specify grouping and can be used to make the intent clear even when they are not required The inner parentheses in the previous example are not necessary, but they don't hurt, either Seasoned programmers might omit them, because the relational operators (< <= == ! = >= >) have higher precedence than the logical operators (&& and I I ) When mixing unrelated operators, though, it's a good idea to parenthesix C and its friends present pernicious precedence problems, and it's easy to make a mistake
SECTION 12
EXPRESSIONS AND STATEMENTS
Because the logical operators bind tighter than assignment, parentheses are mandatory for most expressions that combine them:
w h i l e ((c = getchar())
!= EOF)
The bitwise operators & and I have lower precedence than relational operators like ==, so despite its appearance,
i f (x&MASK == BITS)
actually means
which is certainly not the programmer's intent Because it combines bitwise and relational operators, the expression needs parentheses:
i f ((x&MASK) == BITS)
Even if parentheses aren't necessary, they can help if the grouping is hard to grasp at first glance This code doesn't need parentheses:
leap- year = y % 4 == 0 && y % 100 != 0
I) y
% 400 == 0;
but they make it easier to understand:
We also removed some of the blanks: grouping the operands of higher-precedence operators helps the reader to see the structure more quickly
Break up complex expressions C , C++, and Java have rich expression syntax and operators, and it's easy to get carried away by cramming everything into one construction An expression like the following is compact but it packs too many operations into a single statement:
It's easier to grasp when broken into several pieces:
i f (2kk < n-m) axp = c [ k + l ] ; else *xp = d [k--1 ; *x += *xp;
Be clear Programmers' endless creative energy is sometimes used to write the most concise code possible, or to find clever ways to achieve a result Sometimes these skills are misapplied, though, since the goal is to write clear code, not clever code
