Java Program to Print Matrix in Z Form

In this section, we will discuss how to print the matrix in Z form. Also, we will create a Java program that prints the all the Z elements of the matrix.

The Z form includes the elements of the first row, right diagonal, and the last row of the matrix. To print the Z form of the matrix, the rows and columns must be the same.

Java Program to Print Matrix in Z Form

MatrixZForm.java

  import java.util.Scanner;  public class MatrixZForm  {  //function to print the matrix  static void printMatrix(int arr[][])  {  int row, col;  //loop for rows  for(row=0; row<3;row++)  {  System.out.print(“n”);  //loop for columns  for(col=0; col<3;col++)  {  //prints elements       System.out.print(arr[row][col]+”t”);  }  }  }  //looks for the highest occurrence of 1  static void printZMatrix(int arr[][])  {  int row, col;  //print the first row (first elements of all the columns) of the matrix  for(col=0;col<3;col++)  System.out.print(arr[0][col]+”t”);  System.out.print(“n”);          //prints the right diagonal of the matrix  //row starts from indexing 1 because we have not to print the first and the last element   for(row=1; row<2; row++)  for(col=0;col<3;col++)  //checks if the sum of rows and columns index is equal to 2 or not  //if equal prints the mid element of the first row and first column  if(row+col==2)  System.out.print(“t”+arr[row][col]);  System.out.print(“n”);  //print the last row of the matrix  for(col=0;col<3;col++)  System.out.print(arr[2][col]+”t”);  }  //driver code  public static void main(String args[])  {  //initializing a 3*3 matrix   int arr[][] = {{5,9,1},{3,6,7},{4,8,0}};  System.out.print(“The matrix elements are:”);  //function calling  printMatrix(arr);  System.out.println(“nThe z-form of the matrix is: “);  //function calling  printZMatrix(arr);  }  }   

Output:

Java Program to Print Matrix in Z Form

In the following program, we have printed the elements of the matrix in an array that forms a Z pattern.

MatrixZElements.java

  import java.lang.*;   import java.io.*;   public class MatrixZElements  {  //function to prints the matrix in Z form      public static void diag(int arr[][], int n)   {   int i = 0, j, k;   //prints the first row of the matrix  for (j = 0; j < n – 1; j++)   {  System.out.print(arr[i][j] + ” “);   }   //prints the right diagonal of the matrix  k = 1;   for (i = 0; i < n – 1; i++)   {   for (j = 0; j < n; j++)   {   if (j == n – k)   {   System.out.print(arr[i][j] + ” “);   break;   }   }   k++;   }   //prints the last row of the matrix  i = n – 1;   for (j = 0; j < n; j++)   System.out.print(arr[i][j] + ” “);   System.out.print(“”);   }   public static void main(String args[])   {   //initializing a 4*4 matrix      int a[][] = { { 11, 23, 9, 34 }, { 67, 25, 67, 45 }, { 77, 38, 30, 90 }, { 71, 91, 56, 88 } };   System.out.println(“Z elements of the matrix are: “);  //calling function   diag(a, 4);   }   }  

Output:

Z elements of the matrix are:   11 23 9 34 67 38 71 91 56 88
