Call to List.get can be keyed access

Last modified: 03 December 2024

Reports calls to java.util.List.get() methods. Such calls could be replaced by the shorter and clearer keyed access form.

Example:

def list = ["foo"]
def str = list.get(0) // list.get(0) could be replaced with list[0]

After the quick-fix is applied:

def list = ["foo"]
def str = list[0]
