Answer:
The correct answer to the following question will be "Semantic and Syntax error".
Explanation:
<u>Syntax error: </u>
Corresponds to such a mistake in a pattern sentence structure that is composed in either a specific language of that same coding. Because computer programs have to maintain strict syntax to execute appropriately, any elements of code that would not adhere to the programming or scripting language syntax can result inside a syntax error.
<u>Semantic error: </u>
That would be a logical error. This is because of erroneous logical statements. Write inaccurate logic or code of a program, which results incorrectly whenever the directives are implemented.
So, it's the right answer.
Answer:
//here is the statement in java.
import java.util.*;
//class definition
class Solution
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// this statement will print the 3 2 1 Go! and go to newline
System.out.println("3 2 1 Go!");
}catch(Exception ex){
return;}
}
}
Explanation:
We can use "System.out.println()" to print the required output same as it required. After printing this, it will go to newline.
Output:
3 2 1 Go!

Answer:
b. foreign key
Explanation:
In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.
On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.
In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.
A duplicate key is used when an information may be repeatedly entered on a table.
So the correct option is a foreign key.
