Could some of you please give me some hints, how to make the following pattern with the use of 'for'loop?
*
**
***
****
*****

People here will generally not do your homework for you.
Why not code up what you do know and post your code with questions regarding where you are getting hung up?

I understand your apprehension, and that is the reason I have not asked for codes, just for hints.
First, I know how to generate this pattern without using 'for' loop, which is tedious and not the right way.
Second, I can create a nested 'for' loop and generate the following pattern:
****
****
****
But I do not know, how to increase the '*' in subsequent line.
I would appreciate any hint in this regard.

Use the concatentation operator
bob is of type STRING.
bob = bob + "*";
OR its shorthanded equivalent
bob += "*";
OR a funkier way to do it is by way of:
System.out.print("*")
this will print a string and won't wrap to the next line.
I'd recommend figuring out how to do it using the first way.

Thanks Friend! I have got it.
I have used String X ="X"; and X =X +"X"; It has worked.

With a little bit more thought, I'd bet you could figure it out, without using String concatenation (not that there's anything really wrong with such a solution). Think "nested for loops", as you once did.

I did generate the pattern with nested "for" loop:
for (int i=5; i>=0; i--){
for(int j=i;j>=0; j--){
System.out.print("X");
}
System.out.println();
}

Sorry, It should be increment operator not decrement.
Thanks!
