Sparse Matrix Program in Java

This is a Java Program to Determine if a given Matrix is a Sparse Matrix. If the number of zero elements are more than the non-zero elements of the matrix then it is known as Sparse Matrix

Enter the elements of array as input. Now we use loops and if else condition to check for Sparse Matrix.

Here is the source code of the Java Program to Determine if a given Matrix is a Sparse Matrix. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
import java.util.Scanner;
```
```
public class Sparse
```
```
{
```

    public static void main(String args[])

```
    {
```
```
 	int i, j, zero = 0, count = 0; 
```
```
 	int array[][] = new int[10][10];
```

 	System.out.println("Enter total rows and columns: ");

```
 	Scanner s = new Scanner(System.in);
```
```
 	int row = s.nextInt();
```
```
 	int column = s.nextInt();
```
```
 	System.out.println("Enter matrix:");
```
```
        for(i = 0; i < row; i++)
```
```
        {
```

            for(j = 0; j < column; j++)

```
    	    {
```

                 array[i][j] = s.nextInt();

```
                 System.out.print(" ");
```
```
    	     }
```
```
        }
```
```
        for(i = 0; i < row; i++)
```
```
        {
```
```
 	    for(j = 0; j < column; j++) 
```
```
  	    {
```
```
                if(array[i][j] == 0)
```
```
    		{
```
```
        	    zero++; 
```
```
    		}
```
```
    	   	else
```
```
            	{
```
```
      	            count++;
```
```
    	    	}
```
```
   	   }
```
```
       }
```
```
       if(zero>count)
```
```
       {
```

           System.out.println("the matrix is sparse matrix");

```
       }
```
```
       else
```
```
       {
```

           System.out.println("the matrix is not a sparse matrix");

```
       }
```
```
    }
```
```
}
```

Output:

$ javac Sparse.java
$ java Sparse 
 
Enter total rows and columns: 
3
3
Enter matrix:
1
0
5
0
0
8
0
0
0
the matrix is sparse matrix
