Agile Placement Paper
java:
(1)find out three keywords
(a)synchronized
(b)implement
(c)throws
etc
(2)which are not keywords
(a)NULL
(b)synchronize
etc
(3)two to three questions on legal array declaration
(a)int a[][]=new int[3][3];
(b)int[] a[]=new int[3][3];
(c)int a[3][4]=new int[3][4];wrong
(d)int[3][4] a=new int[3][4];wrong
(e)int a[][]=new int[3][4];
(4)++i+++j is equivalent to
(a)i+j+1
(b)i+j+2
(c)i+j
(d)can’t be compiled(correct)
(5)the content of the array after execution of following statement:int a[][]=new int[3][3];
(a)all elements contain zeros
(6)find legal statements
(a)int a=30;
(b)float f=1.4;(error)
(c)double d=34.5;
(d)byte b=128;(error)
(7)find illegal statements
(a)int i=’2′;
(b)char a=12;
(8)some 5 questions on collection interfaces
(9)to find the length of array
(a)arr.length-1
(b)arr.length(correct)
(c)arr.length()
(10)write code for accessing array length without assigning it to another variable
(11)recursion is
(a)any function which refer itself
(12)the sorting method which don’t generally use recursion
(a)heap sort
(b)bubble sort(ans)
(c)quick sort
(d)bubble sort
(13)one questions regarding abstract
(14)some 2 questions on hash table
C++:
(1)the difference b/w pure virtual fn.& virtual fn.
(a)pure virtual function. is initialized to zero.
(b)
(2)virtual destructor’s are used for
(a)
(3)find legal statement
(a)cout>>”name”>>endl;
(b)cout<<“name<
(c)cout<<“name”<
(4)find the o/p of the program
void main()
{
int a=10;b;
if(a<=10)
b=4;
if(a>10)
b=5;
cout<
}
(a)it don’t be compiled
(b)it compiles and o/p’s 10 4(ans)
(5)a question on copying or assigning
(6)early or static binding means
(a)at runtime
(b)at compile time(ans)
(7)one question on global variables,one qn on globally declared static variable
(8)two question on “vector” type
(9)the branch of a tree which has no childs is called
(10)when a node c is inserting b/w nodes a and b how many pointer will be modified
(a)2(check)
