Question

Aaaado in 

I need quick A. 

 

A. Write a java program that reads three (3) int variables and performs the below
operations:
i.
Prints out their product
ii. Prints out the maximum of the numbers
Do not use any inbuilt Java Methods to return the maximum.
B. Algorithms perform differently on different data sets and as such we may be
interested in either their Best-case, Worst-case or Average-case scenarios.
Explain why the Worst-case for an insertion sort is with reverse-sorted data.
C. Identify and correct the errors in each of the following sets of code:
i.
while ( c <= 5 )
{
ii.
product *= c;
++C;
if ( gender == 1 )
System.out.println("Woman" );
System.out.println("Man" );
What is wrong with the following while statement?
else;
111.
while (z >= 0 )
sum += z;
D. Explain two (2) programming situations that will require the use of overloaded
methods
