If you had a lot of these to do, how would you crank them out?
With an amanuensis that generated source code?
With a keystroke macro of some sort?
With reflection?
with an IDE plugin?
Assume the variable are local.
Way back in the PL/1 days we had PUT DATA to handle this problem.
Perhaps someday Java might have some syntactic sugar to capture the
text of an expression passed to a method and place in a second
parameter, done at compile time.
Perhaps an IDE code template for most situations. For example, in
Eclipse I can write a Java template like
System.out.println("${var} = " + ${var});
I'll point out that IntelliJ has a template for this by default. "soutv"
+ Ctrl-J gives you 'System.out.println("=", |)', where | is where the
caret is placed. It auto-suggests in-scope variables, and will fill in
the left-side of the "=" as you type the expression. I wouldn't be
surprised if other programming editors have similar functionality.
In combination with this, and the fact that in Eclipse you have assisted
toString() generation, thereby taking care of the instance variable
printout heavy-lifting, you've gone a long way towards relieving some of
the drudgery.
IntelliJ also has a "toString" generator, which generates a labels
toString delegating to other fields (which you can select or deselect).
Great for if you just need extra information for debugging logs. Not
great for much else, but a good start at least.
