Consider the following methods:
public static int
secret(
int
x)
{
int
i, j;
7
i = 2 * x;
if
(i > 10)
j = x / 2;
else
j = x / 3;
return
j - 1;
}
public static int
another(
int
a,
int
b)
{
int
i, j;
j = 0;
for
(i = a; i <= b; i++)
j = j + i;
return
j;
}
What is the output of each of the following program segments?
x = 10;
System.out.println(secret(x));
a.
x = 5; y = 8;
System.out.println(another(x, y));
b.
