Shared naming conventions allow teams to collaborate effectively. This rule raises an issue when a local variable or function parameter name does not match the provided regular expression.

Noncompliant Code Example

With the default regular expression ^[a-z][a-zA-Z0-9]*$:

public void doSomething(int my_param) {
  int LOCAL;
  ...
}

Compliant Solution

public void doSomething(int myParam) {
  int local;
  ...
}

Exceptions

Loop counters are ignored by this rule.

for (int i_1 = 0; i_1 < limit; i_1++) {  // Compliant
  // ...
}

as well as one-character catch variables:

try {
//...
} catch (Exception e) { // Compliant
}
