such a mistake, but the implicit (that is, the use of variable representation subscript) calls are often wrong, there is a situation, The length of the array defined in the program is determined by certain methods and is not declared beforehand, so it is better to look at the length of the array before this exception occurs.5. Java.lang.illegalargumentexception the explanation of this anomaly is that the parameters of the quot; method are quot, and many of the methods in the J2ME class

The difference between Collection and collections in Http://www.cnblogs.com/dashi/p/3597937.htmlJava 1, Java.util.Collection is aCollection Interface (a top-level interface of a collection Class)。 It provides a common interface method for basic manipulation of collection objects. The collection interface has many specific implementations in the Java class Library.The meaning of the collection interface is to provide a maximum unified operation for a v

coercion of type conversions. In particular, the Java language does not use pointers, but references. and provides automatic scrap collection, which makes it unnecessary for programmers to worry about memory management. The Java language is object-oriented:The Java language provides object-oriented features such as classes, interfaces, and inheritance, and for

Metrics is a Java library that can provide you with unmatched code-run insight. It was developed by Yammer to detect the health of back-end services on the JVM. Metrics provides a powerful toolset for measuring the behavior of key components in your production environment. Metrics provides a common set of modular libraries for support such as Guice,jetty,log4j,apache httpclient,ehcache,logback,spring, Als

JSTL Core Tag Library has a total of 13 tags, functionally divided into 4 categories: 1. Expression control Tags: out, set, remove, catch 2. Process Control Tag: If, choose, when, otherwise 3. Cyclic Tags: forEach, fortokens 4.URL operation tag: import, URL, redirect When using labels, be sure to include the following code in the header of the JSP file: These labels are described in the following sections: 1.
