Consider the following two code segments. Assume that
the int variables m and n have been properly declared and
initialized and are both greater than 0.
I. for (int 1 = 0; i < m * n; i++)
{
System.out.print("A");
}
II. for (int j - 1; j <= m; j++)
{
for (int k = 1; k < n; k++
,{
System.out.print("B");
}
}
Assume that the initial values of m and n are the same in
code segment I as they are in code II. Which of the
following correctly compares the number of times that "A"
and "B" are printed when each code segment is executed?
A. "A" is printed m fewer times than "B"
B. "A" is printed n fewer times than "B"
C. "A" is printed m more times than "B"
,D. "A" is printed n more times than "B" - ANSWER-C. "A"
is printed m more times than "B"
Consider the following class
public class SomeMethods
{
public void one(int first)
{ / * implementation not shown * / }
publics void one(int first, int second)
, { / * implementation not shown * / }
public void one(int first, String second)
{ / * implementation not shown * / }
}
Which of the following methods can be added to the
SomeMethods class without causing a compile-time error.
I. public void one(int value)
