try (InputStream inputStream = this.getClass().getClassLoader()
                .getResourceAsStream("hello.txt");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream))) {

But sonarQube complaints below error in the above line

Correctness - Nullcheck of value previously dereferenced(line starting with BufferedReader ) .

Please help to resolve this issue

Answer 1

这是因为getClassLoader().getResourceAsStream("hello.txt")可以返回null并且您在创建BufferedReader之后就使用了它，而无需检查null值。
