The square patternin Java is the simplest pattern that you can start with. This pattern makes a shape of a square or you can shape it in a rectangle. Steps to create a square pattern in Java: 1. Define the size of the square (or you can take user input). 2. Create a nested loop where the external loop is the number of rows and the inner loop is the...
The hollow squareis the same as the above pattern but stars only at the borders. Which makes it a hollow square. Steps to create a hollow square pattern in Java: 1. Set size of the square (or take user input). 2. Create a nested loop where the external loop executes the number of rows. 3. In the internal loop, print star in the first and last row a...
The left triangle star patternis also quite a simple pattern. It has a shape of a triangle with its perpendicular line at the left side. Steps to create a left triangle star pattern in Java: 1. Take the size of the triangle. 2. Create a nested loop and repeat the outer loop for times equal to the size of the triangle. 3. Repeat the inner loop for t...
The right triangle star patternis also the same as the left triangle star pattern but it has a shape of a triangle with its perpendicular line at the right side. This is a bit harder than the left triangle star pattern because you also have to deal with spaces in the pattern. Steps to create a right triangle star pattern: 1. Repeat the external loo...
You can see Left down trianglebelow. Here are the steps to create a downward triangle pattern program in Java: 1. Take the size of your triangle. 2. Create an external loop to print rows of triangles. 3. Create an inner loop that print star for times equal to size minus the outer loop index. Output:
You can see Right down trianglebelow. Here is the complete code create downward triangle pattern program in Java: Output:
The hollow triangle star patternis a simple triangle pattern with stars only at its boundary making it hollow. Steps to create hollow triangle pattern program in Java: 1. Set a size for the triangle and create an outer loop to print rows. 2. Inside the inner loop, if the index of the inner loop is last then print star (*) at first and last index of...
The most famous star pattern is the pyramid pattern. Steps to create a pyramid Java pattern programs: 1. Take the size and create an external loop to print all rows. 2. Inside the outer loop, we have to create 2 inner loops. First for printing spaces and second for printing stars. 3. print number of spaces equal to size minus the outer loop index i...
The reverse pyramid star patternis the same as the pyramid star pattern but rotated 180 degrees. This also follows the same logic as the pyramid star pattern just a different loop order. Output:
The hollow pyramidis a hollow pyramid with stars only at corners. Here are the steps to create a Hollow pyramid pattern program in Java: 1. Set size of the hollow pyramid. 2. Inside the external loop, we have to create 2 inner loops. First for printing spaces and second for printing stars. 3. The first loop print a number of spaces equal to size mi...
Sep 9, 2024 · Diamond Pattern. To create star patterns, we’ll use nested “ for” loops. The outer loop controls the number of rows, and the inner loop controls the number of columns (or stars) in each row ...
Aug 12, 2024 · In Java, loops and control statements are used to print patterns. Loops repeat a block of code multiple times, and control statements let you make decisions in your code. Star Patterns in Java. First, let us begin with the basic and commonly asked pattern program in Java i.e Pyramid. 1. Pyramid Program

For i=1, 1<4 (true) For j=1, 1<=1 (true) The first print statement prints two stars at the second row and the second println statement prints the spaces and throws the cursor at the next line. Now the value of i and j is increased to 2. Iteration 3: For i=2, 2<4 (true) For j=2, 2<=2 (true)

Nov 22, 2023 · 80+ Pattern Programs In Java. Java programs to print the numbers or stars or any other characters in different patterns are one of the frequently asked interview programs mostly for freshers. Because, they test the candidate’s logical ability as well as coding skills which are ‘must have skills’ for any software engineer.
