nested for loop for alphabet increment

Question:

I have searched everywhere and I cannot figure out how to create this output using a nested for loop in java:

"a

ab

abc

abcd"

continued until z

this is what I have tried

String alphabet = "abcdefghijklmnopqrstuvwxyz";

for(int i = 0; i <= 25; i++) { for(char j = (char)(alphabet.charAt(i)); j<=i; j++) { System.out.print(j); } System.out.println(); }

Please help me!

Answer1:

Here is the answer:

for (int x = 'a'; x<='z'; x++) { for (int i = 'a'; i<=x; i++) { System.out.print((char)i); } System.out.println(); }

The outer loop switches from one row to another whilst the inner loop prints the characters for that particular row.

Answer2:

Here you go !

<blockquote>

print capital Alphabet

</blockquote> public class Main { public static void main(String[] args) { int i, j; for(i = 1; i<=26; i++) { for(j = 1; j <= 1-i; j++) { System.out.print(" "); for(j = 1; j <= i; j++) System.out.print((char)(char)(i+64)+" "); System.out.println(); //for line break } } }
