One of the most essential components of the Java Interview questions has always been Java Pattern Programs. Although they appear to be hard to solve at times, most often than not, they are just really based on mathematical logic and the principles of matrices.Therefore, pattern programs in java are always in high demand.
Patterns can be designed in a variety of creative, architectural, and behavioral ways to provide answers for instantiating an object in the best feasible way for specific conditions, depending on the pattern structure type.
When designing or changing applications or software programs, software designers employ Design Patterns as a prominent problem-solving strategy. It aids in the creation of simple, well-structured software that testers, developers, and users can understand and utilize.
Maintaining and introducing additional attributions in accordance with version requirements is simple; errors may be detected and promptly fixed if they occur. If necessary, developers can reuse programs; work on multiple interfaces and bridge them.

1. Pyramid Pattern Programs in Java

The pyramid is one of the simple pattern programs in Java that is often asked in interviews.

public class JigSawAcademy

{

public static void PyramidPattern(int n)

{

for (int i=0; i<n; i++) // for number of rows(n)

{ for (int j=n-i; j>1; j–) // a loop for spaces

{

System.out.print(” “); //to print space

}

for (int j=0; j<=i; j++ ) //for number of columns

{

System.out.print(“* “); //to print star

}

System.out.println(); //end-line after every row

}

}

public static void main(String args[]) //driver function,

{

29. Descending Numbers Pattern Program

import java.util.Scanner;

public class JigSawAcademy

{

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

//take a row-value from the user

System.out.println(“How many rows do you want in this pattern?”);

int rows = sc.nextInt();

System.out.println(“Here is your pattern….!!!”);

for (int i = 1; i <= rows; i++)

{

for (int j = rows; j >= i; j–)

{

System.out.print(j+” “);

}

System.out.println();

}

//to close all the resources

sc.close();

}

}

Output:

7 6 5 4 3 2 1

7 6 5 4 3 2

7 6 5 4 3

7 6 5 4

7 6 5

30. Matrix Pattern programs in java

import java.io.*;

class JigSawAcademy

{

//to print the pattern

static void printPattern(int n)

{

// the number of rows & columns to print

int s = 2 * n – 1;

// upper half of matrix

for (int i = 0;

i < (s / 2) + 1; i++)

{

int m = n;

// the decreasing part

for (int j = 0; j < i; j++)

{

System.out.print(m + ” “);

m–;

}

// the constant part

for (int k = 0;

k < s – 2 * i; k++)

{

System.out.print(n – i + ” “);

}

// the increasing part.

m = n – i + 1;

for (int l = 0; l < i; l++)

{

System.out.print(m + ” “);

m++;

}

System.out.println();

}

// lower half of the matrix

for (int i = s / 2 – 1;

i >= 0; i–)

{

// the decreasing part

int m = n;

for (int j = 0; j < i; j++)

{

System.out.print(m + ” “);

m–;

}

// the constant part.

for (int k = 0;

k < s – 2 * i; k++)

{

System.out.print(n – i + ” “);

}

// the decreasing part

m = n – i + 1;

for (int l = 0; l < i; l++)

{

System.out.print(m + ” “);

m++;

}

System.out.println();

}

}

// the driver code

public static void main (String[] args)

{

int n = 3;

printPattern(n);

}

}

Output:

3 3 3 3 3

3 2 2 2 3

3 2 1 2 3

3 2 2 2 3

3 3 3 3 3
