Too weak variable type leads to unnecessary cast

Reports type casts that can be removed if the variable type is narrowed to the cast type.


Object x = " string "; System.out.println(((String)x).trim());

Here, changing the type of x to String makes the cast redundant. The suggested quick-fix updates the variable type and removes all redundant casts on that variable:

String x = " string "; System.out.println(x.trim());
