Collection without initial capacity

Warning

Last modified: 03 December 2024

Reports attempts to instantiate a new Collection object without specifying an initial capacity.

If no initial capacity is specified, a default capacity is used, which will rarely be optimal. Failing to specify initial capacities for collections may result in performance issues if space needs to be reallocated and memory copied when the initial capacity is exceeded. This inspection checks allocations of classes listed in the inspection's settings.

Example:

Use the following options to configure the inspection:

  • List collection classes that should be checked.

  • Whether to ignore field initializers.
