java - 关于我的代码的类型错误的非法开始

Question

当我创建负载时，我的程序出现以下错误；

D:\views\UniqueAcctStorageRuleNameValidator.java:34: illegal start of type
List<String> listOfAcctStorageRuleNameAsArray =
    new ArrayList<>(listOfAcctStorageRuleName.size());

这是代码；

public class FKAcctStorageRuleNameValidator extends AbstractAnnotationCheck<FKAcctStorageRuleName>{

   private static final long serialVersionUID = 1L;

   private SpecbookValidatorManager specBookValidator;   

   @Override
   public boolean isSatisfied(Object validatedObject, Object valueToValidate,
           OValContext context, Validator validator) throws OValException {
      if (valueToValidate == null) return true;

      specBookValidator = SpecbookValidatorManagerImpl.getInstance();

      List<SpecbookAcctStorageRule> listOfAcctStorageRuleName = specBookValidator.getAcctStorageRuleList();

      List<String> listOfAcctStorageRuleNameAsArray = new ArrayList<>(listOfAcctStorageRuleName.size());
      for (SpecbookAcctStorageRule specbookAcctStorageRule : listOfAcctStorageRuleName) {
         listOfAcctStorageRuleNameAsArray.add(specbookAcctStorageRule.getName());
      }

      return ListUtil.containsIgnoreCase((String) valueToValidate, listOfAcctStorageRuleNameAsArray);
   }
}

很可能你使用的JDK版本低于7。它不知道是什么the diamond <> 是。

更改为以下将解决问题:

new ArrayList<String>(listOfAcctStorageRuleName.size());

当然，您可以免费下载更新的 Java 版本以使用以前版本中不允许的所有便利功能。
