Question

Answer 1

when the third loop is execute

third loop is executive five time with each value of i.

As you see what you print in second loop
System.out.print(buff [ i. ]);

is i
for first execution i=0
buff[0]=5;
buff[1]=5;
.
.
.
.
.
buff[5]=5;

note than-->>
the last value where the second loop is terminate is 5

that why you see the
output is
5,0,0,0,0,0
5,5,0,0,0,0
5,5,5,0,0,0
5,5,5,5,0,0
5,5,5,5,5,5

Answer 2

first loop of your code is
for (int i = 0; i < buff.length; i++)
{

second loop is
for (int j = 0; j < sequence.length; j++) {

if ( i==j)
{
j++;
}
buff[i] = sequence[j];

}
}
first point-->
first loop run for 5 time
second loop run for 5 time for each value of first loop..

second point-->
In second loop
you increment the value of i if i and j
are equal
then
after you assign the value of array buff[i]

and your output like this

first execution of loop
i=0
j=0

. j=1

your output is-->>1, 2, 3, 4, 5

second execution
i=1
j=0

your output 10
then after j=1
your output is 10,2,3,4 ,5

fifth execution
i=5
j=0

when j=5

you output is 10,1,2,3,4, 5

-------------------------------------------------------------------
as you see the last digit where the second loop end is always five

continue in second post

Answer 3

i=0
j=0

you print buff[i]

after that you second loop terminate. at buff[0]=5;

third loop come to play
i=0
k=0

buff[k]=5

Answer 4

thank you for help, I already understand where I made the mistake
I will try to correct the error tomorrow
