How to swap 2 numbers without using temp or 3rd variable is mutual interview interrogation non but on Java interviews but too on C in addition to C++ interviews. It is too a good programming questions for freshers . This interrogation was asked to me long dorsum in addition to didn't had whatever thought almost how to approach this interrogation without using temp or 3rd variable, may hold upwards lack of noesis on bitwise operators inwards Java or may hold upwards it didn't click at that time. Given or thence fourth dimension in addition to trial error, I eventually come upwards out amongst a solution amongst but arithmetics operator but interviewer was continue bespeak almost other approaches of swapping 2 variables without using temp or 3rd variable . Personally, I liked this interrogation in addition to included inwards listing o f my programming interview question bec ause of its simplicity in addition to or thence logical work, it forcefulness yous to do. When learned...

Main departure betwixt UTF-8, UTF-16 together with UTF-32 grapheme encoding is how many bytes it require to stand upward for a grapheme inwards memory. UTF-8 uses minimum i byte, piece UTF-16 uses minimum 2 bytes. BTW, if character's code betoken is greater than 127, maximum value of byte together with thus UTF-8 may convey 2, iii o 4 bytes but UTF-16 volition solely convey either ii or iv bytes. On the other hand, UTF-32 is fixed width encoding system together with e'er uses 4 bytes to encode a Unicode code point. Now, let's get-go amongst what is grapheme encoding together with why it's important? Well, grapheme encoding is an of import concept inwards procedure of converting byte streams into characters, which tin last displayed. There are ii things, which are of import to convert bytes to characters , a character set together with an encoding . Since at that spot are thus many characters together with symbols inwards the world, a grapheme laid is required to back ...

There are several ways to convert XMLGregorianCalendar to Date inwards Java. You tin sack convert XMLGregorianCalendar to either java.util.Date or java.sql.Date based upon your need . JAXB (Java API/Architecture for XML Bindings) is a pop framework to practise XML documents from Java Objects together with Java objects from XML files. JAXB too helps to practise Java classes from XML Schema file (.XSD file). By default JAXB maps XSD information type xs:date , xs:time together with xs:dateTime to XMLGregorianCalendar inwards Java, precisely you lot tin sack configure XJC to practise java.util.Date objects instead of javax.xml.datatype.XMLGregorianCalendar . Sin ce java.util.Date is most pop agency of dealing amongst appointment together with fourth dimension inwards Java, nosotros oftentimes demand to convert XMLGregorianCalendar lawsuit to Date lawsuit inwards Java. Thankfully past times using Java API, nosotros tin sack easily practise this conversion of XMLGregorianCalen...
