How to avoid nested null checks [duplicate]

Question

In java is there a way to avoid having to nest null checks on each level of the call to ensure there were no nulls along the way which prevent the next call. Is there an elegant way to do this?

for example:

objOne.objTwo.objThree.objFour.objFive

if(objOne.objTwo!=null){
    if(objOne.objTwo.objThree!=null){
      if(objOne.objTwo.objThree.objFour!=null){
            ...
   }
  }
}

Answer 1

you can collapse the nested if statements into one, using short circuit logic. the first false condition will exit the if statement

if (objOne.objTwo != null && objOne.objTwo.objThree != null && objOne.objTwo.objThree.objFour != null) {
           ...
}
