Write "Java" Program to print below Alphabet Pattern 5 (or) Character Pattern 5:
To understand this example, you should have knowledge of the following topics:
· Java if Else Statement.
Java Character pattern5 program using For loop:
import java.util.Scanner;
class alphabetPattern5
{
public static void main(String[] ags)
{
int i, j,k,n;
System.out.println("Enter the number of lines");
Scanner s = new Scanner(System.in);
n = s.nextInt();
for(i = 1;i <= n;i++)
{
k = i;
for(j = 1;j <= i;j++,k++)
{
System.out.print((char)(k+64));
}
System.out.println();
}
}
Output:
Enter the number of lines 5 A BC CDE

Explanation:
- The first four integers "i", "j", "k" and "n" are declared of type int.
- Then in the First for loop “i” value is initialized with a value 1.
- Now “i” value is checked with the condition i < n that is (where n value is given through Keyboard). If the condition is True loops enter into second for loop.
- Now the loop enters into the second for loop and checks the condition j <= i. Where "j = 1". and the condition is True.
- Now prints the " Alphabet". Print up to second for loop condition becomes False.
- When the value of "i" becomes greater than the "n" value the program terminates.
