Print this pattern in java​

Answer 1

$\texttt{\textsf{\large{\underline{Solution}:}}}$

Correct Pattern will be –

APPLE

APP

A

The co‎‎de –

$\rule{300}{2}$

public class APPLE{

   public static void main(){

       String str="APPLE";

       for(int i=str.length();i>0;i-=2)

           System.out.println(str.substring(0,i));

   }

}

$\rule{300}{2}$

$\texttt{\textsf{\large{\underline{Explanation}:}}}$

• str stores the string.
• substring (x , y) method returns a new string that starts at index x and ends at index y.
• Here, we are displaying substring of the string from first index to i'th index where i = {5,3,1}

See the attachment for output.
