The number of records or rows in a table using MySQL can be got by using the COUNT statement.
Explanation:
- To counts all of the rows in a table, whether they contain NULL values or not, use COUNT
- That form of the COUNT() function basically returns the number of rows in a result set returned by a SELECT statement
- The SQL COUNT() function returns the number of rows in a table satisfying the criteria specified in the WHERE clause.
- It sets the number of rows or non NULL column values.
- COUNT() returns 0 if there were no matching rows.
- The SQL COUNT function is an aggregate function that returns the number of rows returned by a query. You can use the COUNT function in the SELECT statement to get the number of employees, the number of employees in each department, the number of employees who hold a specific job, etc.

Explanation:
import java.util.Scanner;
public class pitcherValues {
public static void main(String[] args) {
String firstName, lastName;
int earnedRuns, inningsPitched;
double ERA;
Scanner in = new Scanner(System.in);
System.out.println("Pitchers First Name is?");
firstName = in.nextLine();
System.out.println("Pitchers Last Name is?");
lastName = in.nextLine();
System.out.println("How many runs did the Pitcher earn?");
earnedRuns = in.nextInt();
System.out.println("How many innings did the Pitcher Pitch?");
inningsPitched = in.nextInt();
ERA = (earnedRuns * 9) / inningsPitched;
System.out.println(firstName + " " + lastName + " has an ERA of " + ERA);
}

Before the use of technology such as computers, information was documented through papers separated in folders. This was a very long and complicated process as people would have to find information by hand, sorting through countless documents. Now, it is much easier and neater to keep information. It can be as easy as digitally searching for someone's name and the computer will sort through countless documents, finding the one you need almost instantly. It is also much less wasteful and safe, as before computers, the use of paper was the only way to permanently keep information, also making documents vulnerable to being lost or stolen.
