Java Program to Calculate the Multiplication of Two Matrices:
public class Main{
	public static void main(String args[]){
		//Create two matrices
		int A[][] = {{1,2},{3,4}};
		int B[][] = {{5,6},{7,8}};

		//Create a new matrix to store the result of multiplication
		//2 rows and 2 columns	
		int C[][] = new int[2][2];  

		//multiplication
		for(int i=0; i<2; i++){
			for(int j=0; j<2; j++){ 
				C[i][j] = 0;    
				for(int k=0; k<2 ;k++)    
				{ 
					C[i][j] += A[i][k] * B[k][j];    
				}
				System.out.print(C[i][j]+" "); 
			}
			System.out.println();
		}  
	}
}
