In Java programming, the DatatypeConverter class is a utility class that provides methods to convert between different data types. It is part of the java.xml.bind package and is commonly used for XML and JSON processing. The DatatypeConverter class was introduced in Java 6 and has been enhan...

This is necessary to configure the datatype converter that should be used to perform the print and parse conversions. Calling this api repeatedly will have no effect - the DatatypeConverterInterface instance passed into the first invocation is the one that will be used from then on. Parameters...

For example, Java collections only work with objects. They cannot take primitive types. Wrapper classes also include some useful methods. For example, they include methods for doing data type conversions. Placing primitive types into wrapper classes is calledboxing. The reverse process is called...
You can perform various operations oncharvalues, such as comparisons (==,!=), arithmetic operations (using the underlying Unicode values), and type conversions. Thechardata type in Java allows you to work with individual characters and perform operations on them. It is widely used when dealing...
有时候,以不同形式描述对象中的properties很有用。例如,一个Date可以用人类可读的方式来描述。这可以通过注册自定义的java.beans.PropertyEditor类型的editor来实现(--卧槽,刚意识到这不是Spring的东西),嗯,注册在BeanWrapper上或者IoC容器中。详见Javadoc。
Specifically, rather than using methods in the customMyDataTypeConverterclass to perform these data type conversions, the Datatype Converter example uses the built-in methods provided byjavax.xml.bind.DatatypeConverter: <xsd:simpleType name="ZipCodeType"> ...
