FOR JAVA, Average Of Row Table

public abstract class Final {

private int row;

private int column;

public int[ ][ ] table;

public Final(int r, int c) {

row = r;

column = c;

table = new int[row][column];

}

public void hi() {

System.out.println("hi");

}

public abstract void fillTable( );

public abstract double[] averageOfRowTable( );//

/*for example, if table has:

1 2 3
4 5 6
7 8 9

Your method should return: 2.0, 5.0, 8.0 */ public abstract void printTable( ); // print table elements } // end of the Final class

1. Write a class that uses the Final abstract class defined above.
2. The class should fill the table with random numbers between “0” and ”upper bound” value.
3. Be sure, the class should have a property to hold the “upper bound” value.

4. Implement your class constructor considering (it means your constructor must get the upper bound value,also consider exceptions for invalid parameters)

5. Write a Test class and test all methods that have been Implemented.
