Write a Java program to print repeated character pattern or alphabets in each row pattern using for loop.
package Alphabets; import java.util.Scanner; public class RepeatedCharPat1 { private static Scanner sc; public static void main(String[] args) { sc = new Scanner(System.in); System.out.print("Enter Repeated Character Pattern Rows = "); int rows = sc.nextInt(); System.out.println("Printing Repeated Character/Alphabets Pattern"); int alphabet = 65; for (int i = 0 ; i < rows; i++ ) { for (int j = 0 ; j <= i; j++ ) { System.out.print((char)alphabet + " "); } alphabet++; System.out.println(); } } }
This example program displays the right triangle pattern of repeated characters in each row using a while loop.
package Alphabets; import java.util.Scanner; public class RepeatedCharPat2 { private static Scanner sc; public static void main(String[] args) { sc = new Scanner(System.in); System.out.print("Enter Repeated Character Pattern Rows = "); int rows = sc.nextInt(); System.out.println("Printing Repeated Character/Alphabets Pattern"); int i = 0, j, alphabet = 65; while(i < rows ) { j = 0 ; while( j <= i ) { System.out.print((char)alphabet + " "); j++; } alphabet++; System.out.println(); i++; } } }
Enter Repeated Character Pattern Rows = 8

The below shown program will print the repeated characters or alphabets pattern using do while loop.
package Alphabets;
import java.util.Scanner;
public class RepeatedCharPat3 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Rows = ");
int rows = sc.nextInt();
System.out.println("Printing Repeated Character/Alphabets Pattern");
int i = 0, j, alphabet = 65;
do
{
j = 0 ;
do
{
System.out.print((char)alphabet + " ");
} while( ++j <= i ) ;
alphabet++;
System.out.println();
} while(++i < rows );
}
}
Enter Rows = 12
