问Java中字符串数的加减运算EN将这两个数字作为字符串，将符号存储到符号字符串中，并将其存储到相应的numbers对象中，然后调用您的方法，如下所示 !
addBatch 方法将 100000 个整数添加到名为 NUMBERS 的集合中。当然,如果我们需要这些数据,这完全没问题。但在这种情况下,我们永远不会删除它。即使我们在 main 方法中创建了StaticReferenceLeak 对象并且没有持有对它的引用,我们也很容易看出垃圾收集器无法清理内存。相反,它不断增长: ...
To supply implementations of cryptographic services, an entity (e.g., a development group) writes the implementation code and creates a subclass of the Provider class. The constructor of the Provider subclass sets the values of various properties; the JDK Security API uses these values to look ...
