Pyramid out of letters

Question

I tried to make a pyramid out of letters but i am not that familiar with how to change letters i made one but i got a result a little but different from what i expected
Char a='a';
for(int i =1;i<=5;i++){
For(int j=0;j<i;j++){
System.out.print(a +" ");
a++;

}
System.out.println(" ");
}

The result
a
b c
d e f
g h i j
k l m n o
What i expected
a
a b
a b c
etc
and i know that there are codes already made about pyramids out of letters but i wrote the question in order to understand how to change letters and so on .

Put a='a' in first for loop.
