Sharing some coding conventions is a key point to make it possible for a team to efficiently collaborate. This rule make it mandatory to place left curly braces at the beginning of lines of code.
The following code snippet illustrates this rule:
public void myMethod
{ // Compliant
if(something)
{ // Compliant
executeTask();
} else { // Non-Compliant
doSomethingElse();
}
}
