**Spiral matrix in java: **In the previous article, we have seen Java Program to Print Matrix in Z form

In this article we are going to see how we can write a program to how to print Matrix in spiral from.

## Java Program to Print the elements of the Matrix in Spiral Form

A 3*3 Matrix is having 3 rows and 3 columns where this 3*3 represents the dimension of the matrix. Means there are 3*3 i.e. total 9 elements in a 3*3 Matrix.

Let’s understand it in more simpler way.

| A00 A01 A02 | Matrix A = | A10 A11 A12 | | A20 A21 A22 | 3*3

`Matrix A`

represents a 3*3 matrix.- ‘
`A`

‘ represents the matrix element. - ‘
`Aij`

‘ represents the matrix element at it’s matrix position/index. - ‘
`i`

‘ represents the row index - ‘
`j`

‘ represents the column index - Means
`A00=Aij`

where`i=0`

and`j=0`

,`A01=aij`

where`i=0`

and`j=1`

and like this. - Here we have started
`row`

value from 0 and`column`

value from 0.

Let’s see different ways to print Matrix in spiral from.

### Method: Java Program to Print the elements of the Matrix in Spiral Form By Static Initialization of Array Elements

**Approach:**

- Initialize and declare a matrix.
- Traverse the matrix through [0,0] point and traverse by row wise.
- Take 1st for loop to move from left to right.
- Take 2nd for loop to move top to bottom.
- Take 3rd for loop to move right to left.

**Program:**

import java.util.*; public class Main { public static void main(String args[]) { int mat[][]={{10,20,30},{40,50,60},{70,80,90}}; int a = 0; int b = mat.length-1; int c = 0; int d = mat[0].length-1; while(a <= b && c <= d) { for (int x = a; x <= d; x++) { System.out.print(mat[a][x] + " "); } for (int x = a+1; x <= b; x++) { System.out.print(mat[x][d] + " "); } if(a+1 <= b) { for (int x = d-1; x >= c; x--) { System.out.print(mat[b][x] + " "); } } if(c+1 <= d) { for (int x = b-1; x > a; x--) { System.out.print(mat[x][c] + " "); } } a++; b--; c++; d--; } } }

Output: 10 20 30 60 90 80 70 40 50
