Pattern variable can be used
Reports local variable declarations that can be replaced with pattern variables, which are usually more compact.
Example:
if (obj instanceof String) {
String str = (String) obj;
System.out.println(str);
}
Can be replaced with:
if (obj instanceof String str) {
System.out.println(str);
}
This inspection only reports if the language level of the project or module is 16 or higher
