Multiplication of two Matrix 

     

This is a simple java program that teaches you for multiplying two matrix to each other. Here providing you Java source code with understanding the Java developing application program. We are going to make a simple program that will multiply two matrix. Two dimensional array represents the matrix. 

Now, make this program, you have to declare two multidimensional array of type integer. Program uses two for loops to get number of rows and columns by using the array1.length. After getting both matrix then multiply to it. Both matrix will be multiplied to each other by using 'for' loop. So the output will be displayed on the screen command prompt by using the println() method.  

Here is the code of this program:

class MatrixMultiply{
  public static void main(String[] args)  {
  int array[][] {{5,6,7},{4,8,9}};
  int array1[][] {{6,4},{5,7},{1,1}};
  int array2[][] new int[3][3];
  int x= array.length;
  System.out.println("Matrix 1 : ");
  for(int i = 0; i < x; i++) {
  for(int j = 0; j <= x; j++) {
  System.out.print(" "+ array[i][j]);
  }
  System.out.println();
  }  
  int y= array1.length;
  System.out.println("Matrix 2 : ");
  for(int i = 0; i < y; i++) {
  for(int j = 0; j < y-1; j++) {
  System.out.print(" "+array1[i][j]);
  }  
  System.out.println();
  }
  
  for(int i = 0; i < x; i++) {
  for(int j = 0; j < y-1; j++) {
  for(int k = 0; k < y; k++){
  
  array2[i][j+= array[i][k]*array1[k][j];
  }
  }  
 }
  System.out.println("Multiply of both matrix : ");
  for(int i = 0; i < x; i++) {
  for(int j = 0; j < y-1; j++) {
  System.out.print(" "+array2[i][j]);
  }  
  System.out.println();
  }
  }
}
