Java - modification of local variables

Question

I have a trivial, but irritating problem in Java. Suppose we have the following class and method: ``` class A{ void doSth(int[] array){ int index1, index2, index3; int value1, value2, value3; if(array[index1] > 10){ //Long code modifies value1, value2, value3 } if(array[index3] > 100){ //Same long code modifies value1, value2, value3 } if(array[index2] > 20){ //Same long code modifies value1, value2, value3 } } ``` Disregarding what this is trying to achieve, I would like to somehow make this redundancies disappear. usually, I would pass the values to a hlper method, but I can't, since the block is modifying local variables. Any idea how to simplify this?

Accepted Answer

It sounds like you `value1`, `value2` and `value3` probably have some meaning in combination. So encapsulate them into a separate class, and at that point you can call a method which either modifies an existing instance or returns a new instance of that class. Either way, with a single local variable you'll be fine.
