Java. Only need the calculate sum part. Please use the template, thank you!
Transcribed Image Text:Problem 10: Table
Given a Table class (Table.java ), fill in two methods: neighborAverage (int row, int
column) and sum(int i, boolean horizontal).See the template for more details.
Examples:
Table table =
new Table (4, 5); // 4 x 5 table
/ *
* Fill it with a sequence of values:
* 6 9 12 15 18
8 12 16 20 24
* 10 15 20 25 30
* 12 18 24 30 36
* /
for (int i = 0; i < 4; i++) {
for (int j
= 0; j < 5; j++) {
table.set(i, j, (3 + i)
(2 + j));
}
}
table.sum (0, true); // returns 60.0
table.sum (0, false); // returns 36.0
table.sum (1, true); // returns 80.0
table.sum (1, false); // returns 54.0
table.sum (2, true); // returns 100.0
table.sum (2, false); // returns 72.0
table.sum (3, true); // returns 120.0
table.sum (3, false); // returns 90.0
table.sum ( 4, false); // returns 108.0
