Conditional execution increases code nesting and decreases readability. When the body of a method or loop ends with code that is conditionally executed, it can be simplified by inverting the condition with a ``++continue++`` or early ``++return++``.


This rule raises an issue when a method or loop ends with a conditional block containing at least two statements.


== Noncompliant Code Example

[source,text]
----
public void conditionalMethod()
{
  if (condition) // Noncompliant
  {
    doFirstThing();
    doSecondThing();
    doThirdThing();
  }
}

public void conditionalLoop() 
{
  for(int i = 0; i < 10; i++)
  {
    if (condition)  // Noncompliant
    {
      doTheThing();
      doTheOtherThing();
    }
  }

  if (otherCondition) // Compliant
  {
    doTheFinalThing();
  }
}
----


== Compliant Solution

[source,text]
----
public void conditionalMethod()
{
  if (!condition) 
  {
    return;
  }
  doFirstThing();
  doSecondThing();
  doThirdThing();
}

public void conditionalLoop() 
{
  for(int i = 0; i < 10; i++)
  {
    if (!condition) 
    {
      continue;
    }

    doTheThing();
    doTheOtherThing();
  }

  if (otherCondition)
  {
    doTheFinalThing();
  }
}
