Call to 'toString()' on array

Reports arrays used in String concatenations or passed as parameters to methods, such as System.out.println().

Usually, the content of the array is meant to be used and not the array object itself.


void print(Object[] objects) { System.out.println(objects); }

After the quick-fix is applied:

void print(Object[] objects) { System.out.println(Arrays.toString(objects)); }
