Which of the following is good coding practice to determine oddity?<br>i)<br><pre><code class="java">public boolen abc(int num){return num % 2 == 1;}</code></pre><br>ii)<br><pre><code class="java">public boolean xyz(int num){return (num &amp; 1)!= 0; }</code></pre>

Correct Answer: ii

Consider the 5 × 5 matrix \[{\text{A}} = \left[ {\begin{array}{*{20}{c}} 1&2&3&4&5 \\ 5&1&2&3&4 \\ 4&5&1&2&3 \\ 3&4&5&1&2 \\ 2&3&4&5&1 \end{array}} \right

Eigen values of the matrix \[\left[ {\begin{array}{*{20}{c}} 0&1&0&0 \\ 1&0&0&0 \\ 0&0&0&{ - 2i} \\ 0&0&{2i}&0 \end{array}} \right

Let A be an m × n matrix and Ban n × m matrix. It is given that determinant ($$I$$m + AB) = determinant ($$I$$n + BA), where $$I$$k is the k × k identity matrix. Using the above property, the determinant of the matrix given below is
\[\left[ {\begin{array}{*{20}{c}} 2&1&1&1 \\ 1&2&1&1 \\ 1&1&2&1 \\ 1&1&1&2 \end{array}} \right

Which of the following php statement/statements will store 111 in variable num?
1. int $num = 111;
2. int mum = 111;
3. $num = 111;
4. 111 = $num;

What is the right choice, if the following loop is implemented?
void main(){ int num = 0; do{ --num; printf("%d", num); }while( ++num >= 0 );}

What will be the content of num, after code execution; if before code execution num has value 200?
If num500 Num=num*3;Endif

What will be the content of num, after the code execution; if before code execution num has value 90?
If num500 Num=num*3;Endif

What will be the content of num, after code execution; if before code execution num has value 1000?
If num500 Num=num*3;Endif
 

interface Base{ boolean m1 (); byte m2(short s);}

which two code fragments will compile?
1. interface Base2 implements Base {}2. abstract class Class2 extends Base { public boolean m1(){ return true; }}3. abstract class Class2 implements Base {}4. abstract class Class2 implements Base { public boolean m1(){ return (7 > 4); }}5. abstract class Class2 implements Base { protected boolean m1(){ return (5 > 7) }}

The eigen values of the following matrix are \[\left[ {\begin{array}{*{20}{c}} { - 1}&3&5 \\ { - 3}&{ - 1}&6 \\ 0&0&3 \end{array}} \right
