I often run into code that has to perform lots of checks and ends up being indented at least five or six levels before really doing anything. I am wondering what alternatives exist.

Below I’ve posted an example of what I’m talking about (which isn’t actual production code, just something I came up with off the top of my head).

public String myFunc(SomeClass input) {     Object output = null;      if(input != null)     {         SomeClass2 obj2 = input.getSomeClass2();         if(obj2 != null)         {             SomeClass3 obj3 = obj2.getSomeClass3();             if(obj3 != null && !BAD_OBJECT.equals(obj3.getSomeProperty()))             {                 SomeClass4 = obj3.getSomeClass4();                 if(obj4 != null)                 {                     int myVal = obj4.getSomeValue();                     if(BAD_VALUE != myVal)                     {                         String message = this.getMessage(myVal);                         if(MIN_VALUE <= message.length() &&                            message.length() <= MAX_VALUE)                         {                             //now actually do stuff!                             message = result_of_stuff_actually_done;                         }                     }                 }             }         }     }     return output; }
