pyramid_patterns

A collection of different Pyramid patterns in Java.

Pattern 1

The first pattern is the one from image above - this is a pyramid with numbers. Each number is printed exactly the number of times it denotes - means 1 is printed once, 2 is printed twice, 3 is printed thrice and so on.

There is leading white space of rows-i where i is the number of rows - for e.g in first row there is 4 white spaces, 3 in second and so on.

There is a function created for creating the login for the pattern, which is common in all cases, and one function which only prints

Pattern 2

The second pattern is the image above - this is a pyramid pattern where numbers keep increasing on each row.

There is leading white space of rows-i where i is the number of rows - for e.g in first row there is 7 white spaces, 6 in second and so on.

Now for the numbers, you can see the with each row the count of numbers are increasing - so we have the logic where this happens.

Pattern 3

The third pattern is the one from image above - this is a pyramid with * instead of numbers. Each * is printed exactly the number of times it denotes - means 1 is printed once, 2 is printed twice, 3 is printed thrice and so on.

There is leading white space of rows-i where i is the number of rows - for e.g in first row there is 4 white spaces, 3 in second and so on.

The logic for printing * is same as pattern 1, in place of numbers, you print the character.

Pattern 4

The fourth pattern is one from the image above - this is a pyramid where the numbers decrease up to mid and then increase from the mid.

Pattern 5

This is the inverted star pattern - just the opposite of the one from Pattern 3.
