我越来越违反声纳：

“条件不应无条件地评估为“ TRUE”或“ FALSE””

对于下面的代码。

List<MediaContent> savedList = source.getChildMediaContents();
List<MediaContent> supplierList = target.getChildMediaContents();

// if existing and incoming both empty
if(savedList == null && supplierList == null){
    return false;
}

// if one is null and other is not then update is required
if(savedList == null && supplierList != null){
    return true;
}

if(savedList != null && supplierList == null){
    return true;
}

在两个if块下面，它给出错误

// if one is null and other is not then update is required
if(savedList == null …

声纳给出了一个错误，FileOutputStream应该将其关闭。我需要修改以下代码才能使用try-with-resources。我该怎么做呢？

public void archivingTheFile(String zipFile){
    byte[] buffer = new byte[1024];
    try{
        FileOutputStream fos = new FileOutputStream(zipFile);
        ZipOutputStream zos = new ZipOutputStream(fos);
        for(String file : this.fileList){
            ZipEntry ze= new ZipEntry(file);
            zos.putNextEntry(ze);
            FileInputStream in = new FileInputStream(SOURCE_FOLDER + File.separator + file);
            int len;
            while ((len = in.read(buffer)) > 0) {
                zos.write(buffer, 0, len);
            }
            in.close();
        }
        zos.closeEntry();
        zos.close();
    }catch(IOException ex){
        LOGGER.error("Exception occurred while zipping file",ex);
    }
}

如何将以下代码转换为 JAVA 8 - try-with-resource。我用 java 6 编写了这段代码，我已将 java 6 升级到 java 8 - 声纳给出 Blocker 消息“应该使用 Try-with-resources”

 public void archivingTheFile(String zipFile){
    byte[] buffer = new byte[1024];
    try{
        FileOutputStream fos = new FileOutputStream(zipFile);
        ZipOutputStream zos = new ZipOutputStream(fos);
        for(String file : this.fileList){
            ZipEntry ze= new ZipEntry(file);
            zos.putNextEntry(ze);
            FileInputStream in = new FileInputStream(SOURCE_FOLDER + File.separator + file);
            int len;
            while ((len = in.read(buffer)) > 0) {
                zos.write(buffer, 0, len);
            }
            in.close();
        }
        zos.closeEntry();
        zos.close();
    }catch(IOException ex){
        LOGGER.error("Exception occurred while zipping file",ex); …
