Why do you not declare several variables of the same type on the same line?

Question

Why is it bad practice to declare variables on one line?

e.g.

private String var1, var2, var3

instead of:

private          


        

Answer 1

Here's my reasons:

• Readability, easier to spot if you know there's only one on each line
• Version control, less intra-line changes, more single-line additions, changes, or deletions, easier to merge from one branch to another
