java - nested for loop for alphabet increment -


I have searched everywhere and how can I create this output in Java by using nested for loop:

"a

ab

abc

abcd"

until z

That's what I've tried.

string alphabet = "abcdefghijklmnopqrstuvwxyz"; 

 for  (int i = 0; i & lt; = 25; i ++) {for (char j = (char) (Alphabet.charAt (i)); j &   
 Please help me!  < / Div> 
 
 
 Here is the answer: {for (int i = 'a'; i & lt; = x; i ++) {System.out}  
 for  (int x = 'a'; x & lt; = 'z'; x ++) print ((four) i);} system.out .println ();}   
 The external loop switches from one line to another, while the internal loop prints the characters of that particular line.
