1, I have code like
        FileInputStream fis = new FileInputStream(filename);
        int x = fis.available();
        byte b[] = new byte[x];
        fis.read(b);
        String content = new String(b);
        System.out.println(content);
2, use hint "Surround \block with try-catch" on the first line

-> result looks strange, why there is the "try { fis = null" ?

        FileInputStream fis = null;
        try {
            fis = null;
        try {
            fis = new FileInputStream(filename);
            
            int x = fis.available();
            
            byte[] b b = new byte[x];
            
            fis.read(b);
            String content = new String(b);
            System.out.println(content);
        } catch (FileNotFoundException ex) {
            Exceptions.printStackTrace(ex);
        } finally {
            try {
                fis.close();
            } catch (IOException ex) {
                Exceptions.printStackTrace(ex);
            }
        }
            String content = new String(b);
            System.out.println(content);
        } catch (FileNotFoundException ex) {
            Exceptions.printStackTrace(ex);
        } finally {
            try {
                fis.close();
            } catch (IOException ex) {
                Exceptions.printStackTrace(ex);
            }
        }
