Java if statement with 2 conditions and common code

I have 2 conditions to check, if one condition is true, I need to carry out some code and if another condition is true, I need to carry out some different code. However, if either is true, I need to carry out a common piece of code in addition to the specific code.

Note only one of the 2 conditions can be true, not both.

So, I could do this in 3 ways:

Method 1

if (condition1 || condition2){

    //common code here
    commonCode();
    moreCommonCode();

    //Dig a bit deeper to see which one was true
    if (condition1){

        //Carry out some code here specific to condition1
        specificToCondition1();
        moreCondition1Stuff();

    }

    else {

        //Carry out some code here specific to condition2
        specificToCondition2();
        moreCondition2Stuff();

    }

}

Method 2

if (condition1){

   specificToCondition1();
   moreCondition1Stuff();

}

else if (condition2){
    specificToCondition2();
    moreCondition2Stuff();

}

if (condition1 || condition2){

    commonCode();
    moreCommonCode();

}

Method 3

if (condition1){

    specificToCondition1();
    moreCondition1Stuff();
    commonCode();
    moreCommonCode();

}

else if (condition2){

    specificToCondition2();
    moreCondition2Stuff();
    commonCode();
    moreCommonCode();

 }

in Method 1 and Method 2, I need to check the conditions twice.

In Method 3 I have to duplicate the common code.

Am I missing something and is there a way to do this where I nether have to duplicate the code or check the conditions twice?
