In this noncompliant code example, OUT_STR_LEN must always be exactly two greater than IN_STR_LEN. The These definitions fail to reflect this requirement. :
| Code Block | ||
|---|---|---|
| ||
public static final int IN_STR_LEN = 18; public static final int OUT_STR_LEN = 12; |
Compliant Solution
The In this compliant solution, the relationship between the two values should be is represented in the definitions.:
| Code Block | ||
|---|---|---|
| ||
public static final int IN_STR_LEN = 18; public static final int OUT_STR_LEN = IN_STR_LEN + 2; |
...
In this noncompliant code example, there appears to be an underlying relationship between the two constants , when in fact there is nonewhere none exists.
| Code Block | ||
|---|---|---|
| ||
public static final int ADULT_AGE = 18; public static final int ALCOHOL_AGE = ADULT_AGE + 3; |
A programmer performing routine maintenance may modify the definition for ADULT_AGE but fail to recognize the resulting change in the definition for ALCOHOL_AGE.
Compliant Solution
