There are two ways: 1. Catch the exception and handle it yourself. 2.throw go out and let someone else handle it.As an example:public class a{ try{ A statement that could release an exception ... }catch (Exception e) { E.getmessage ();//Handle yourself }}public class A throws exception{ A statement that could release an exception ...}//throw out and let someone else handle it.Note that this is throws.If you use the throw in the methodExample:public class a{ try{ A state

Applications often require text-processing functions, such as Word lookup, e-mail acknowledgement, or XML document integration. This usually involves pattern matching. Languages such as Perl, sed, or awk use regular expressions to improve pattern matching, and the regular expression is a string of characters that can be defined to find matching text. In order to use the JavaTM programming language for patte

This article discusses the similarities and differences between Java and C # in order to let Java developers master some of the knowledge involved when migrating to. NET. The main similarities between Java and C # are: java and C # are all derived from C + +, and there are some features of C + +.

"Although based on C + +, Java is a more purely object-oriented programming language." Both C + + and Java are part of the hybrid language. But in Java, designers find this miscellaneous merger not as important as in C + +. The hy

: Flow: represents any continuous stream of data from a data source that is represented by a set of attributes. Operator: A functional component of a stream data processing that receives one or more input streams, processes the tuples and attributes corresponding to the convective data, and eventually produces one or more output streams. Input port: A port used to receive output streams from other operators. Output port: The port used to generate the output stream. Processing element (PE):

Whether the study of Java programming or other programming language, are from the Zero Foundation, then the need to integrate all the scattered knowledge points, so that the systematic learning of a language, to better get started and mastered, through the basic knowledge of

The last one mentioned is to write Java in Chinese and not as a new language. As a Chinese language, grammar structures that require language to provide keywords are used in Chinese. The simplest thing to do is simply to replace the Java keyword with the Chinese key word. do

Although Java does not have the dynamic language like the violence, but still days, water to produce many framework technology---reflection (reflection), generics (generics), meta-data (annotation), proxies (proxy/cglib), Code dynamic Generation ( ASM), AOP (AspectJ), Dynamic language embedding (Groovy/javascript/beanshell). In the face of these, we like the over
