Question

I am writing Java app.

This is a sample of my code:

int [] digitPart_1 ={16,7,9,8,5,6,};
int [] digitPart_2 ={1,77,98,86,5,6,};
int [] digitPart_3 ={166,7,49,84,55,6,};

for(int i = 0; i < mfl.size(); i++){
 new DataProcessing(digitPart_+""+(i + 1));
}

In my design now each part (e.g. digitPart_1) shall be passed in, because 0 + 1 = 1, 1 + 1 = 2, i.e. digitPart_1 etc. But that causes compile error. It does not let me modify the name of array I pass in.
The ‘mfl’ is not important, it shall store number 3. I was just wondering whether I can modify the the name of data-structure I pass in dynamically like you can modify string you pass in to the output stream.

Any suggestion on how to overcome this issue?
Cheers

Answer 1

you cannot modify varaibles’ name dynamically. but you can use an array instead:

int[][] digitPart = {{16,7,9,8,5,6}, {1,77,98,86,5,6}, {166,7,49,84,55,6}};

for(int i = 0; i < mfl.size(); i++){
   new DataProcessing(digitPart[i]);
}
