how to do validation part in java , i have 5 fields i need verify validation for all these 5 fields
Hi here i have total 5 fields,all these are not mandatory fields
From UI end i am selecting these values clicking on submit button.
i can select any of the field and inserting into DB,once the value inserted in DB,It should not accept the value again.
The below are the fields:
1.state
2.pid
3.kst
4.DM
5.ped
now from the application i am selecting the state value and clicking submit button
here i am checking the condition
i have total 5 fields
here i am seeing total 16 scenarios how can i check all the possible scenarios
i can use else if conditions upto all 16 scenarios but is there any logic to use all the scenarios in short form

now from the application i am selecting the state value and clicking submit button
here i am checking the condition
if(state!=null and pid==null and kst==null and DM==null and ped==nul){
if{
//here i am checking these values are already there in DB or not
//if values are not there in DB then i am inserting these values into respective table.
}
}else if(...)
{
}
like this i need to check all the scenariosi have total 5 fields
here i am seeing total 16 scenarios how can i check all the possible scenarios
i can use else if conditions upto all 16 scenarios but is there any logic to use all the scenarios in short form
It seems to me that whatever the combination is you can do the same check:
check if a record having the given values for state, pid, kst, DM and ped is already in the table.
Or do I understand this wrong?

i am doing the same but i need to keep more else if blocks
For this i did one alternative
by using or condition i cut down many else if blocks
For this i did one alternative
if(condition 1 || condition2 || condition3 || condition 4){
//here i am checking db validation as well (conditon1 ||conditon2 ||condition3 ||condition4)
}else if( condition5 || condition6 || condition 7 || condition 8){
//here i am checking db validation as well (conditon4 ||conditon5 ||condition6 ||condition7 ||condition 8)
}
by using or condition i cut down many else if blocks
With that pseudo-code, it's very difficult to tell whether that's valid or even necessary. Generally what are these conditions?
Indeed some more specifics would help a lot. The more specific you are the better we can help you.
eg. in your code
what does "checking these values are already in DB or not" mean.
Do you check if "a record with state = the given state and the 4 other fields = null" exists or what?
eg. in your code
if(state!=null and pid==null and kst==null and DM==null and ped==nul){
if{
//here i am checking these values are already there in DB or not
//if values are not there in DB then i am inserting these values into respective table.
}
}

in the earlier post i have gave the scenario
let suppose condition1 means
if((state!=null and pid==null and kst==null and DM==null and ped==nul)||(state!=null and pid!=null and kst==null and DM==null and ped==null){
//if(condition1)or (condition2)
let suppose from ui screen i entered only state and rest of the fields are null
at that time condition1 vl satisfy and it vl go inside
and one more scenario ivl give the value like state and pid that second condition vl satisfy
let suppose condition1 means
if((state!=null and pid==null and kst==null and DM==null and ped==nul)||(state!=null and pid!=null and kst==null and DM==null and ped==null){
//if(condition1)or (condition2)
let suppose from ui screen i entered only state and rest of the fields are null
at that time condition1 vl satisfy and it vl go inside
and one more scenario ivl give the value like state and pid that second condition vl satisfy
I understand very well that if you enter only state in the UI that the condition1 is true.
And that if you enter state and pid then the condition2 is true. (after all, I can read java code ;-)
And I understand that you don't want to write 16 if statements to cover all possible scenarios.
But to know if you can group some of the 16 conditions together, I try to understand what is inside those if statements
If I don't know that, I can't help. Sorry.
In other words: please explain as detailed as possible what this does:
>> //here i am checking these values are already there in DB or not
>> //if values are not there in DB then i am inserting these values into respective table.
Also, you still didn't answer CEHJ's question:
>> Please also post the table definition
Kind advise:
If you want us to help you, please answer our questions, or tell us why you (think) that's an irrelevant question.
But don't just neglect them or experts will do the same with your question.

Hi CEHJ,
These all 5 fields not in the same table
it is the combination of 3 tables
i am using the query and with these 3 table and fecthing the values
it is not possible for me to provide complete table information

i completed this task by placing or(||).
You'd have probably simplified the code (and readability) by using EnumSet

HI CEHJ,
could u plz explore how to use Enumset
