Java Code To Create Pyramid and Pattern
In this examples, you’ll learn to create pyramid, half pyramid, inverted pyramid, Pascal’s triangle and Floyd’s triangle sing control statements in Java.
Print half pyramid using * in Java
1 2 3 4 5 6 7 8 9 10 11 | public static void main(String[] args) { int rows = 5; for(int i = 1; i <= rows; ++i) { for(int j = 1; j <= i; ++j) { System.out.print("* "); } System.out.println(); } } |
Output:
Program to print half pyramid using star in java
Inverted full pyramid using * in Java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | public static void main(String[] args) { int rows = 5; for(int i = rows; i >= 1; --i) { for(int space = 1; space <= rows - i; ++space) { System.out.print(" "); } for(int j=i; j <= 2 * i - 1; ++j) { System.out.print("* "); } for(int j = 0; j < i - 1; ++j) { System.out.print("* "); } System.out.println(); } } |
Output:
Inverted full pyramid using star in Java
Print half pyramid a using numbers in Java
1 2 3 4 5 6 7 8 9 10 11 | public static void main(String[] args) { int rows = 5; for(int i = 1; i <= rows; ++i) { for(int j = 1; j <= i; ++j) { System.out.print(j + " "); } System.out.println(); } } |
Output:
Program to print half pyramid using alphabets in Java
1 2 3 4 5 6 7 8 9 10 11 | public static void main(String[] args) { char last = 'X', alphabet = 'O'; for(int i = 1; i <= (last-'O'+1); ++i) { for(int j = 1; j <= i; ++j) { System.out.print(alphabet + " "); } ++alphabet; System.out.println(); } |
Output:
Program to print half pyramid using alphabets in Java
Program to print full pyramid using * in Java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | public static void main(String[] args) { int rows = 5, k = 0; for(int i = 1; i <= rows; ++i, k = 0) { for(int space = 1; space <= rows - i; ++space) { System.out.print(" "); } while(k != 2 * i - 1) { System.out.print("* "); ++k; } System.out.println(); } } |
Output:
Program to print full pyramid using star in Java
