Answer:
b. data entry slows as every INSERT , UPDATE, or DELETE statement must also update every index.
Explanation:
This process help to improve the speed of get data , it takes each element in the indexed column and save the location to get faster the data. But if you index every attribute in a table it going to take a lot of time locating each column in the respective index in each query(update, delete and insert). For that reason is necesary be carefull with this process and only put index in the relevant columns
Answer:
public static void printDottedLine(){
System.out.print(".....\n");
}
Explanation:
This method returns nothing so its return type is void
It also accepts no parameters so the argument list is empty
When called it executes the System.out.print(".....\n"); which prints out 5 dots
See a complete program below:
public class TestClock {
public static void main(String[] args) {
printDottedLine();
}
public static void printDottedLine(){
System.out.print(".....\n");
}
}
