Write a Java program to print triangle of same alphabets pattern in each row using for loop.
package Alphabets;
import java.util.Scanner;
public class TriangleSameAlpeachRows1 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Triangle of Same Row Alphabets Rows = ");
int rows = sc.nextInt();
System.out.println("Printing Triangle of Same Alphabets in each Row");
int alphabet = 65;
for (int i = 0; i <= rows - 1; i++)
{
for (int j = rows - 1; j > i; j-- )
{
System.out.print(" ");
}
for(int k = 0; k <= i; k++)
{
System.out.print((char)(alphabet + i) + " ");
}
System.out.println();
}
}
}
This Java program prints the triangle of same alphabet in each single row using a while loop.
package Alphabets;
import java.util.Scanner;
public class TriangleSameAlpeachRows2 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Triangle of Same Row Alphabets Rows = ");
int rows = sc.nextInt();
System.out.println("Printing Triangle of Same Alphabets in each Row");
int i, j, k, alphabet = 65;
i = 0;
while( i <= rows - 1)
{
j = rows - 1;
while(j > i )
{
System.out.print(" ");
j--;
}
k = 0;
while(k <= i)
{
System.out.print((char)(alphabet + i) + " ");
k++;
}
System.out.println();
i++;
}
}
}

{
System.out.print((char)(alphabet + i) + " ");
} while(++k <= i);
System.out.println();
} while( ++i <= rows - 1) ;
