Question

write a program to print the following pattern of blue j. please give me the correct answer my exams are near .​

Answer 1

Answer:

This can be solved using charAt( )

______________

Note:-

1. charAt() is used for extracting the charter at a particular position(here,index of string)
2. String index starts from 0 to n-1 where n is the no. of characters. This is the reason why loop is starting from 0.
3. print() will print in same lines
4. println() will print in different lines

Variable Description:-

1. str:- to store string data
2. i:- loop variable
3. j:- loop variable

Answer 2

$\textsf{\Large \textbf{Methods Used}}$

   $\textsf{\large - charAt(\textbf{int} i)}$

          $\textsf{Returns the character at the specified location \textbf{i}.}$

   $\textsf{\large - r \hspace{-.67em} epeat(\textbf{int} count)}$

          $\textsf{Returns a string whose value is the concatenation of the string r \hspace{-.67em} epeated.}$

$\textsf{\Large \textbf{Algorithm}}$

• $\textsf{\large Iterating over the String and obtaining each character.}$

• $\textsf{\large R \hspace{-.67em} epeating the character obtained \textbf{i} times.}$

• $\textsf{\large Printing the r \hspace{-.67em} epeated String hence, creating the pattern.}$
