1) Java program to find addition of two matrices

class AddMatrixClass{  
	public static void main(String args[]){  
		/*initialize two matrices*/   
		int m1[][]={{1,1,1},{2,2,2},{3,3,3}};    
		int m2[][]={{4,4,4},{5,5,5},{6,6,6}};    

		/*creating third matrix to store 
		the sum of m1 and m2 matrices */   
		int m3[][]=new int[3][3];  

		/*add and print addition of m1 and m2 matrices */   
		for(int i=0;i<3;i++){    
			for(int j=0;j<3;j++){    
				m3[i][j]=m1[i][j]+m2[i][j];      
				System.out.print(m3[i][j]+" ");    
			}    
			System.out.println();  
		}
	}
}

Output

D:\Java Articles>java AddMatrixClass
5 5 5
7 7 7
9 9 9

2) Java program to find subtraction of two matrices

class SubstractMatrixClass{  
	public static void main(String args[]){  
		/*initialize two matrices*/   
		int m1[][]={{1,1,1},{2,2,2},{3,3,3}};    
		int m2[][]={{4,4,4},{5,5,5},{6,6,6}};    

		/*creating third matrix to store 
		the substraction of m1 and m2 matrices */   
		int m3[][]=new int[3][3];  

		/* substract and print substraction of m1 and m2 matrices */   
		for(int i=0;i<3;i++){    
			for(int j=0;j<3;j++){    
				m3[i][j]=m1[i][j]-m2[i][j];      
				System.out.print(m3[i][j]+" ");    
			}    
			System.out.println();  
		}    
	}
}

Output

D:\Java Articles>java SubstractMatrixClass
-3 -3 -3
-3 -3 -3
-3 -3 -3
