Explanation:
The new code segment is
int feb = 28;
if ((year % 4) == 0 && (year % 100) != 0) // assume that year is an integer with a valid year value
{
System.out.println("This is a leap year");
feb = 29;
}
Assume year = 2020, the assigned value of feb is 29;
Reason below;
At line 2 of the new code segment, two conditions are tested both of which must be satisfied.
1. year % 4 == 0
2020 % 4 = 0
0 = 0 (True)
2. year % 100 != 0
2020 % 100 != 0
20 != 0 (True)
Since both conditions are true, the value assigned to feb will be 29 and
"This is a leap year" will be printed without the quotes
The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word <u>SET</u>, followed by the name of the column to be updated, an equals sign, and the new value.
Explanation:
- An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.
- The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.
- Update Queries let you modify the values of a field or fields in a table.
<u>UPDATE Syntax
</u>
- UPDATE table_name
- SET column1 = value1, column2 = value2, ...

UPDATE table_name SET column1 = value1, column2 = value2, etc WHERE condition;
- table_name: name of the table
- column1: name of first , second, third column....
- value1: new value for first, second, third column....
- condition: condition to select the rows for which the
