You should capitalize names of your classes. After doing that do this in your school class, Classroom cls = new Classroom(); cls.setTeacherName(newTeacherName); Also I’d recommend you use some kind of IDE such as eclipse, which can help you with your code for instance generate getters and setters for you. Ex: right click Source -> Generate … Read more
Alternative DOM Approach Alternatively, instead of doing a brute force traversal of the XML document you could use the XPath capabilities in the JDK to find the “B” element with value “13” and then remove it from its parent: import java.io.File; import javax.xml.parsers.*; import javax.xml.transform.*; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamResult; import javax.xml.xpath.*; import org.w3c.dom.*; public class … Read more
The HttpUrlConnection is buffering the data so that it can set the Content-Length header (per HTTP spec). One alternative, if your destination server supports it, is to use “chunked” transfers. This will buffer only a small portion of data at a time. However, not all services support it (Amazon S3, for example, doesn’t). Another alternative … Read more
public class SQLServerUnicodeDialect extends org.hibernate.dialect.SQLServerDialect { public SQLServerUnicodeDialect() { super(); registerColumnType(Types.CHAR, “nchar(1)”); registerColumnType(Types.LONGVARCHAR, “nvarchar(max)” ); registerColumnType(Types.VARCHAR, 4000, “nvarchar($l)”); registerColumnType(Types.VARCHAR, “nvarchar(max)”); registerColumnType(Types.CLOB, “nvarchar(max)” ); registerColumnType(Types.NCHAR, “nchar(1)”); registerColumnType(Types.LONGNVARCHAR, “nvarchar(max)”); registerColumnType(Types.NVARCHAR, 4000, “nvarchar($l)”); registerColumnType(Types.NVARCHAR, “nvarchar(max)”); registerColumnType(Types.NCLOB, “nvarchar(max)”); registerHibernateType(Types.NCHAR, StandardBasicTypes.CHARACTER.getName()); registerHibernateType(Types.LONGNVARCHAR, StandardBasicTypes.TEXT.getName()); registerHibernateType(Types.NVARCHAR, StandardBasicTypes.STRING.getName()); registerHibernateType(Types.NCLOB, StandardBasicTypes.CLOB.getName() ); } }
Taken from this link: http://www.regular-expressions.info/unicode.html Check the Unicode Character Properties section. \p{L} matches a single code point in the category “letter”. If your input string is à encoded as U+0061 U+0300, it matches a without the accent. If the input is à encoded as U+00E0, it matches à with the accent. The reason is that … Read more
You’re missing the log4j.properties or log4j.xml in your classpath. You can bypass this by using BasicConfigurator.configure(); But beware this will ONLY log to System.out and is not recommended. You should really use one of the files above and write to a log file. A very simple example of log4j.properties would be #Log to Console as … Read more
There are two different aspects. First, there is only a single pipeline which is either sequential or parallel. The choice of sequential or parallel at the inner stream is irrelevant. Note that the downstream consumer you see in the cited code snippet represents the entire subsequent stream pipeline, so in your code, ending with .collect(Collectors.toSet());, … Read more
You should be able to specify your own EntityResolver, or use specific features of your parser? See here for some approaches. A more complete example: <?xml version=”1.0″?> <!DOCTYPE foo PUBLIC “//FOO//” “foo.dtd”> <foo> <bar>Value</bar> </foo> And xpath usage: import java.io.File; import java.io.IOException; import java.io.StringReader; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.xpath.XPath; import javax.xml.xpath.XPathFactory; import org.w3c.dom.Document; import … Read more
jxl is designed for increased read efficiency (since this is the primary use of the API). In order to improve performance, data which relates to output information (eg. all the formatting information such as fonts) is not interpreted when the spreadsheet is read, since this is superfluous when interrogating the raw data values. However, if … Read more
Why does the code above compile at all? Phone seems unrelated to Roamable to me? yes because Roamable is an interface it might cause a Run-time exception but not compile time exception, because even if Phone doesn’t implement Roamable, a subclass of Phone might, hence the compiler has no way to know it but at … Read more
