where * is a blank space for each line
i used array of strings
String []s1=new String [20]
for 5 blank spaces i used s1+" " + " "..+(5)""
then 4 blank spaces and print required charcters
i want to know how i can put it in a good logical general code

r
er

uter
puter
mputer
omputer

i am not getting the blank spaces

System.out.print(s3[j]);
}
System.out.println();
}
}
}
output
r
er
ter
uter
puter
mputer
omputer
computer
no clue about spaces; tabs,string =" ",'\0' all tried but for loop use gives me a weird output

Line 10 - Null terminator in a String is a C concept. Don't worry about it in Java.

I don't understand what your are "reversing" and why. You don't need to reverse anything. You could, of course, since there's more than one way of doing this, but you don't have to.

You should post the desired output, the actual output, and the code itself. Post ALL of this in code tags.

In your loop, there is no attempt to display a space. that's why you don't have any spaces. You don't need a character array. You have your string and that's good enough:
