program to multiply two arrays in java code example

Example: matrix multiplication in java

public class MatrixMultiplicationExample{  
    public static void main(String args[]){  
    //creating two matrices    
    int a[][]={{1,1,1},{2,2,2},{3,3,3}};    
    int b[][]={{1,1,1},{2,2,2},{3,3,3}};    
        
    //creating another matrix to store the multiplication of two matrices    
    int c[][]=new int[3][3];  //3 rows and 3 columns  
        
    //multiplying and printing multiplication of 2 matrices    
    for(int i=0;i<3;i++){    
    for(int j=0;j<3;j++){    
    c[i][j]=0;      
    for(int k=0;k<3;k++)      
    {      
    c[i][j]+=a[i][k]*b[k][j];      
    }//end of k loop  
    System.out.print(c[i][j]+" ");  //printing matrix element  
    }//end of j loop  
    System.out.println();//new line    
    }    
    }}
