3.8. Inserting Method Parameter Names
Problem
You forgot the parameters of a method you want to call, and instead of receiving hints in tool tips (see the previous recipe), you want Eclipse to fill in the parameter names in your code for you.
Solution
Select Window→ Preferences→ Java→ Editor→ Code Assist, and check the “Fill argument names on method completion” and “Guess filled argument names” checkboxes.
Discussion
When you check these checkboxes, code assist automatically fills in
names of the parameters passed to that method in your code. For
example, say you’ve typed
java.util.Arrays.fill
, and you press Ctrl-Space to
invoke code assist, then you select one of the methods code assist
offers you. Code assist will insert names for each parameter into
your code, and as you tab between them, it displays their type in a
tool tip, as shown in Figure 3-11.
