UGC NET Computer Science Solved Question Paper July 2018 Paper II

A valid XML document is defined in the XML specification as a well-formed XML document which also conforms to the rules of a Document Type Definition (DTD).

Initially, f() is called. Then this.y shall display the local value of the variable y which is 6. Next g() is the function which is just defined but it will not get executed untill it is called. Only once g() is called and then it will display y which is the value of global variable=12

Please note that this coding scheme does not need detailed information about Javascript. This is based on the concept of local and global variables and the scope of the variable.

For more information on scope of variable, you may Read this. You will be able to clear the concept of scope of variables.

Array is an object in Java. Array is always passed by value just like any object is passed by object reference i.e. by value in Java. So, the will be no change in the value of the array passed to R. Thus, the result shall remain same i.e. 12.

To understand the concept of run time variables and call by value/ reference in Java or C you can Read this. This document provides enough data for this concept.

The m.two[0]=0000 0101

The m.two[1]=0000 0010

Then it will be stored as 0000 0010 0000 0101 //as it is little endian

Then the union has the size as the size of the longest data type. Although short int and char array of 2 gives same size, the size is max which is 2 Bytes.

The last value will be 2^9 + 2^2 + 2^0=517

For more details on union, you may refer this document from RICE university. This is a powerpoint presentation and is enough for clarifying doubts and make basic understanding. Short enough to save time and attempt relevant questions in exam.

Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.

For points 1 and 2, keep basic understanding of classes, abstract classes and inheritance. For this, refer This Document.

For Java Overriding, this document is enough to clear concepts.
