Question

WAP in java using scanner to print pattern...................................................

Answer 1

import java.util.Scanner; public class MainClass { public static void main(String[] args) { Scanner sc = new Scanner(System.in); //Taking rows value from the user System.out.println("How many rows you want in this pattern?"); int rows = sc.nextInt(); System.out.println("Here is your pattern....!!!"); //Printing upper half of the pattern for (int i = 1; i <= rows; i++) { for (int j = 1; j <= i; j++) { System.out.print(j+" "); } System.out.println();

$\Huge\textbf{\underline{\underline{Answer;}}}$

$\textbf{\textsf{import\:java.util.*;}}$

$\textbf{\textsf{class \:pattern}}$

{

$\textbf{\textsf{Scanner\:sc\:=\:new\:Scanner(System.in);}}$

$\textbf{\textsf{System.out.println("Enter\:the\:no\:of\:terms\:=\:");}}$

int n= sc.nextInt();

{

for(int i=n ; i>=0; i--)

{

for(int j = 0; j<=i; j++)

{

$\textbf{\textsf{System.out.print((char)(j+65));}}$

}

$\textbf{\textsf{System.out println();}}$

}

}

}

The required pattern:

ABCDE
ABCD
ABC
AB
A
