DongChunHao opened a new issue, #7288:
URL: https://github.com/apache/netbeans/issues/7288
### Apache NetBeans version
Apache NetBeans 21
### What happened
When I select the statement "this. value=value;" and perform the extract
method refactoring, the new method name is "newMethod" and I click "OK", a
syntax compilation error occurs:
class ExtractMethodTest {
private final int value;
public ExtractMethodTest(int value) {
// extract method
this.value = value;
}
}
The refactoring results are as follows (Error : The final field
ExtractMethodTest.value cannot be assigned):

Expected result: Check for compilation errors before refactoring, and if
there are any errors, give developers a prompt in advance.
### Language / Project Type / NetBeans Component
