Nobody is going to write the code for you. That's not how this works, at all. What have you tried? Where are you stuck?

Read the link in my signature on asking questions the smart way. Provide an SSCCE that demonstrates where you're stuck, ask a specific technical question, and we'll go from there.

import java.io.*;
public class pattern1
{
public static void main (String[] args) throws IOException
{
InputStreamReader read = new InputStreamReader(System.in);
BufferedReader in = new BufferedReader(read);
int i,j,n=0,k;
System.out.print("How many stars you want to print in first row ? ");
n=Integer.parseInt(in.readLine());
for (i = 0; i<n; i=i+2)
{
for (j=i; j<n;j++)
System.out.print ("*");
System.out.println();
if(i<n)
System.out.print(" ");
}
}
}

in the above code i can print 1 space in second line. but i want to print 2 stace in 3rd line and 3 space in 4th line

output as follows---
How many stars you want to print in first row ? 7

arunjib, just to let you know I have deleted many of your other posts which were duplicates and in the incorrect location. As Kevin mentioned, please refrain from doing this and if you have a question, simply start a new thread.

Thank u sir. i am sorry for doing that. now my question is posted in this thread. this thread is created by me. hope i shall get this problem solved through this forum.

{
for (j=i; j<n;j++)
System.out.print ("*");
System.out.println();
}
}
}

but in the above code i cannot print 1 leading space in 2nd line and 2 leading space in 3rd line.
Please help me.

sir i want to print spaces using for loop. but i am unable to do that. as i am not strong on nested for loop. may i get a complete help from this site/thread without thinking more? if so i shall be greatful. if not i just want to quit my question as i am upset on it. if i had much knowledge i must not put a beginner level question. i am sorry if i do anything mistake here in this net.

Hint: Maybe you should write a method that takes two parameters, a character and an int, that prints out the character that number of times.

Do you know A, B, C, D .... Z ? Can you remember how first time you learnt alphabet ? Was you thinking or reading reapedly ? No ! you just taken help from your teacher (or mom or dad). So as i cannot do this i need just a solution not a teacher like you. I really cannot fine anything to do this. Moreover i am not cheating anybody.

If you aren't strong on nested for loops, take my suggestion of writing a method. That way you don't have to deal with nested for loops directly.

Thank you sir,
I was really depressed on the problem. Atlast i could solve my problem with help of my teacher. Thank you once more for your support. I hope i shall try to read and understand your instructions calmly in future. Please forgive me!

I have told you what to do, in more than one way. If you don't understand something about it, ask. Have you tried to create a method that prints out a character a certain number of times? If not, then do not complain about your inability to follow instructions. If so, post your attempt and ask a specific question about it.

Or think about it this way- how would you do this "by hand"? Pretend you have a friend who has no idea how to draw the pattern you need. What steps would you give him, so that he could follow them and accomplish your goal? Make sure each step is very specific and very short, otherwise your friend will become confused. When you have those steps written out, you'll have an algorithm that should be pretty easy to translate into code.

If I see another negative comment from you, I'm done trying to help you. There are too many other people, who actually want to learn and are willing to follow directions, that I could be helping instead. Nobody is going to simply hand over the code, and if they did, you wouldn't be learning from it anyway.

Thank you sir for your kind co-operation and giving proper guide. I i get permission i want to start another problem here. Can I?

Thee process of working through a problem and hitting that "ah-ha!" moment are really important to learn. I don't try to be mean, but we simply cannot give out answers to homework like that.

I'm glad you eventually got it figured out.

thanks.......................
