Answer:

jspService()

Explanation:

<u></u>

<u>These are the steps in JSP life cycle</u>

1. We have to convert JSP page to Servlet.

2.Then we compile the JSP page which convert it into test.java

3. In test.java ,we load the classes(test.class) in container.

4. Object(instance) is created in container .

5. Then, we initialize the init() method at the time of servlet generation.

6. After the initialization,for the requests we use _jspService() method to serve the incoming requests from JSP.

7. When the work of JSP is completed, we remove it from container by the help of jspDestroy() method.

There is no jspService() method in the JSP life cycle.

3.E.eid , E.sal, E.hobby ,E.did , D.did, D.floor ,D.dname , D.budget.

4.E.eid , D.dname

Explanation:

The attributes that are examined for the query are the attributes of the table that are mentioned in the select statement and where clause.

So according to first query we are working on all attribues of Emp table so all of the attributes of Emp table are examined.In second query we selecting all attributes of both the tables hence all attributes of both the table and same in the next query.

In fourth query though the query is not complete where clause is missing but we have eid from Emp and dname from Dept tables for sure and the attributes mentioned in where clause will also be present.

Rina8888 [55]

Answer:

import java.util.Scanner;

public class DataConstraint {

public static void main(String[] args) {

System.out.print("Enter month, day, year separated by spaces :");

Scanner sc=new Scanner(System.in);

int M,D,Y;

M=sc.nextInt();

D=sc.nextInt();

Y=sc.nextInt();

if(1<=M && M<=12 && 1<=D && D<=31 && Y>=1)

{

if(M==4 || M==6 ||M==9 || M==11){

if(D==31) {

System.out.println("month "+M+" can not have more than 30 days");

System.exit(0);

}

else if(M==2)

{

if((Y%400==0) || (Y%4==0 && Y%100!=0)) {

if(D>=30) {

System.out.println("month "+M+" cannot have "+D+" days");

System.exit(0);

}

else {

if(D>=29) {

System.out.println(Y+" is not a leap year, "+D+" is invalid");

System.exit(0);

}

System.out.println(M+" "+D+" "+Y+" is a valid date");

}

else{

if(1>=M || M>=12) System.out.println(M+" is not a valid month");

if(1>=D || D>=31) System.out.println(D+" is not a valid date");

if(Y<1) System.out.println("year can not be negative");

}

Explanation:

Use a conditional statement to check the month is between 1 and 12.
Check that the date is between 1 and 31 and year must be positive value.
If no. of days are more than 29, then the year cannot be a leap year.
