Groovy tip 10 simplified string operations in groovyIn groovy, operations on string objects are as convenient as operations on List objects. For example, in Java, the substring method is used for operations on string objects. As follows: String STR = "abcdefg"; system. Out. Println (Str. substring (); the result is: BC has two inconveniences: first, the complexity of the substring method and parameters; sec

VM, but groovy relies on JDK1.4 because groovy uses the JDK1.4 core library. However, for the additions to these Java 5, it is definitely necessary to use the Java 5 bytecode. For example, the resulting class might contain bytecode information that represents a run-time retention policy annotation. So while Groovy1.5 can run on JDK1.4, some of groovy's features can only be used on JDK1.5-this is the

converted to map, and then the constructor is new. Note that if map has a property value that is not in a class, an error occurs. 7. astype In groovy, such code may often be seen. [Java] view plaincopy String A = '78' Int B = A as int Print B The second row has the keyword as. It can be seen that the function is to convert string type A to int type B. How does it work? It is very simple. It is to delegate this operation to the astype method of
