Oracle:
1) Indexing and different Types. Explain
2) Explain about cursors.
3) Shared Pool
4) Can we drop a column?
5) Can we rename column?
6) Explain about free and used
J2EE:
1) Explain views in rational model
2) Why you do packaging?
3) EJB: If web container and EJB container, how communication happens. Is remote or Local? Is remote object are pass by reference
4) Composition? Explain
5) Polymorphism
6) Interfaces
7) System.out.println(): Explain
8) Switch and bulb. Design ??
9) What are the services EJB can provide?? Without EJB how can we implement same
10)
Private interface (){
Private test(); // can we declare like this
Static test1(); // can we declare like this
}
11)Class A{
Public void xxx() {
}
}
Class B extends A {
Void xxx(){
// Overridding
}
Void xxx(int c){
// Overloading
}
}
12)
class Test {
private void test1(int a) {
System.out.println(“value of a =” + a);
}
public static void main(String[] args){
Test t1 = new Test();
t1.test(‘a’);
}
}
13)
import java.util.*;
class Testing{
private void testString(){
String test = "BBB";
ArrayList aList = new ArrayList();
System.out.println(" Pankaja1 aList.size() = "+aList.size());
System.out.println(" Pankaja1 test = "+test);
testString2(test, aList);
System.out.println(" Pankaja2 test = "+test);
System.out.println(" Pankaja2 aList.size() = "+aList.size());
}
private void testChar(int x){
System.out.println(" Pankaja1 testChar x = "+x);
}
private void testString2(String pTest, ArrayList pList){
pTest = "AAAA";
pList.add("Pankaja");
System.out.println(" testString2 pList.size() = "+pList.size());
}
public static void main(String[] args)
{
System.out.println("testing !!!!");
Testing aTesting = new Testing();
aTesting.testString();
aTesting.testChar('a');
}
}
Output:
Pankaja1 aList.size() = 0
Pankaja1 test = BBB
testString2 pList.size() = 1
Pankaja2 test = BBB // Sting value cannot be pass by reference value
Pankaja2 aList.size() = 1 // arraylist size = 1 because of pass by reference value.
Pankaja1 testChar x = 97
14) What does finalize() method do?
/**
* Method executeGetSequenceSP
*
* To execute the procedure GENERATE_SEQUENCE To get next
* service request Id
*
* @param intClientId, strSeqName
* @param strSeqName
*
*
* @return
*
* @throws Exception
*/
public int executeGetSequenceSP(int intClientId, String strSeqName)
throws Exception {
Connection con = null;
int intSequence = 0;
CallableStatement cstmt = null;
int intSeq = 0;
try {
con = getConnection();
String sql = "{call generate_sequence( ?, ?, ? ) }";
cstmt = con.prepareCall(sql);
// register output parameter types
cstmt.registerOutParameter(3, java.sql.Types.INTEGER);
// set input parameters
cstmt.setInt(1, intClientId);
cstmt.setString(2, strSeqName);
// execute stored procedure
cstmt.execute();
// retrieve values
intSequence = cstmt.getInt(3);
} catch (SQLException sqlex) {
throw sqlex;
} finally {
try {
if (cstmt != null) {
cstmt.close();
}
} catch (Exception e) {}
finally {
releaseConnection(con);
}
}
return intSequence;
