how to check if your query is empty using java

I'm using a spring framework and the code I'm using won't work or check if the query is null, though I used a .isEmpty() method it doesn't mean that the query is empty. I wanted to make sure that my query is empty because a part of my code does invoke an id in which case I didn't even though its null so please help me T.T
public List<Object> searchEmployee(EmployeeSearchDto data) {
Session session = sessionFactory.openSession();

You're using wrong order and wrong function to compare string:
Replace:
data.getEmployeeID()!="" && data.getEmployeeID()!=null
With
data.getEmployeeID() != null && !data.getEmployeeID().equals("")
Comparing string must use equals(). And check for null should be done first, before accessing the equals method
You should correct other conditions as above too.

Actually, the logic that Mr. Nguyễn provided here is faulty. An object or variable cannot both be null and initialized to a default value (such as foo == "") at the same time.
At the time of the logic check, if the String is in fact null, the second half of the logic statement will engage, checking to see if the String is equal to "", which will throw a null pointer exception. Instead of checking for both at the same time, check for one and then check for the other like so:
//since two logic checks are being performed,
//it is advantageous to put the data from the query
//into memory so you don't have to get the
//same result twice
String foo = data.getEmployeeID();
if (foo != null)
{
if (!(foo.equals("")))
{
//the result is neither null or empty
}
else
{
//the result is not null but it is empty
}
}
else
{
//the result is null
}

How to add field in jtable java

How can insert this set of code in jtable. The problem is when I do md.addElement(id); it shows me a red underline on addElement()
Here is my code
public class hospitalisation extends javax.swing.JFrame {
DefaultTableModel md = new DefaultTableModel();
public hospitalisation() {
initComponents();
hospitalisationtable.setModel(md);
buttonGroup1.add(male);
buttonGroup1.add(female);
}
private void addBtnActionPerformed(java.awt.event.ActionEvent evt) {
String id = "id: " + idtxt.getText();
String name = "name: " + nametxt.getText();
String sex = "sex:";
String address = "address: " + addresstxt.getText();
String sdate = "sdate: " + sdatetxt.getText();
String room = "room: " + cs_room.getSelectedItem().toString();
String father = "father: " + fathertxt.getText();
String phone = "phone: " + phonetxt.getText();
String age = "age: " + agetxt.getText();
String edate = "edate " + edatetxt.getText();
if (female.getModel().isSelected() == true)
sex += female.getText();
else if (male.getModel().isSelected() == true)
sex += male.getText();
md.addElement(id);
md.addElement(name);
md.addElement(sex);
md.addElement(address);
md.addElement(sdate);
md.addElement(room);
md.addElement(father);
md.addElement(phone);
md.addElement(age);
md.addElement(edate);
}

it shows me a red underline on addElement()
this is because as you can see here there is no DefaultTableModel.addElement(String) in that class...
Consider instead taking a look at the doc and maybe consider one of the given methods
like
addColumn(Object columnName)
addColumn(Object columnName, Object[] columnData)
addColumn(Object columnName, Vector columnData)
addRow(Object[] rowData)
addRow(Vector rowData)

return array from inside an if,for statement

I am building a tag reader for inventory purpose. Using the for loop to iterate through the tags to count/total the ids. I get an error on my return line "tagsFound cannot be resolved into a variable". How do i use the variable inside the for loop and then access it outside the loop?
public String[] getTags(AlienClass1Reader reader)throws AlienReaderException{
int coneCount = 0;
int drumCount = 0;
// Open a connection to the reader
reader.open();
// Ask the reader to read tags and print them
Tag tagList[] = reader.getTagList();
if (tagList == null) {
System.out.println("No Tags Found");
} else {
System.out.println("Tag(s) found: " + tagList.length);
for (int i=0; i<tagList.length; i++) {
Tag tag = tagList[i];
System.out.println("ID:" + tag.getTagID() +
", Discovered:" + tag.getDiscoverTime() +
", Last Seen:" + tag.getRenewTime() +
", Antenna:" + tag.getAntenna() +
", Reads:" + tag.getRenewCount()
);
//tagFound[i]= "" + tag.getTagID();
String phrase = tag.getTagID();
tagFound[i] = phrase;
String delims = "[ ]+";
String[] tokens = phrase.split(delims);
if (tokens[0].equals("0CCE") && tokens[3].equals("1001")){drumCount++;}
if (tokens[0].equals("0CCE") && tokens[3].equals("1004")){coneCount++;}
String[] tagsFound;
tagsFound[i] = tag.getTagID();
}
System.out.println("Cones= " + coneCount);
System.out.println("Drums= " + drumCount);
// Close the connection
reader.close();
return tagsFound;
}
}

public String[] getTags(AlienClass1Reader reader)throws AlienReaderException{
int coneCount = 0;
int drumCount = 0;
// Open a connection to the reader
reader.open();
// Ask the reader to read tags and print them
Tag tagList[] = reader.getTagList();
if (tagList == null) {
System.out.println("No Tags Found");
} else {
System.out.println("Tag(s) found: " + tagList.length);
String[] tagsFound = new String[tagList.length];
for (int i=0; i<tagList.length; i++) {
tagsFound = "";
Tag tag = tagList[i];
System.out.println("ID:" + tag.getTagID() +
", Discovered:" + tag.getDiscoverTime() +
", Last Seen:" + tag.getRenewTime() +
", Antenna:" + tag.getAntenna() +
", Reads:" + tag.getRenewCount()
);
//tagFound[i]= "" + tag.getTagID();
String phrase = tag.getTagID();
tagFound[i] = phrase;
String delims = "[ ]+";
String[] tokens = phrase.split(delims);
if (tokens[0].equals("0CCE") && tokens[3].equals("1001")){drumCount++;}
if (tokens[0].equals("0CCE") && tokens[3].equals("1004")){coneCount++;}
tagsFound[i] = tag.getTagID();
}
System.out.println("Cones= " + coneCount);
System.out.println("Drums= " + drumCount);
// Close the connection
reader.close();
return tagsFound;
}
}
the returned array will have empty strings in the positions where the tag does not satisfy the criteria.

java.lang.ArrayIndexOutOfBoundsException :

I have a String = "abc model 123 abcd1862893007509396 abcd2862893007509404", if I provide space between abcd1 & number eg. abcd1 862893007509396 my code will work fine, but if there is no space like abcd1862893007509396, I will get java.lang.ArrayIndexOutOfBoundsException, please help ?:
PFB the code :
String text = "";
final String suppliedKeyword = "abc model 123 abcd1862893007509396 abcd2862893007509404";
String[] keywordarray = null;
String[] keywordarray2 = null;
String modelname = "";
String[] strIMEI = null;
if ( StringUtils.containsIgnoreCase( suppliedKeyword,"model")) {
keywordarray = suppliedKeyword.split("(?i)model");
if (StringUtils.containsIgnoreCase(keywordarray[1], "abcd")) {
keywordarray2 = keywordarray[1].split("(?i)abcd");
modelname = keywordarray2[0].trim();
if (keywordarray[1].trim().contains(" ")) {
strIMEI = keywordarray[1].split(" ");
for (int i = 0; i < strIMEI.length; i++) {
if (StringUtils.containsIgnoreCase(strIMEI[i],"abcd")) {
text = text + " " + strIMEI[i] + " "
+ strIMEI[i + 1];
System.out.println(text);
}
}
} else {
text = keywordarray2[1];
}
}
}

After looking at your code the only thing i can consider for cause of error is
if (StringUtils.containsIgnoreCase(strIMEI[i],"abcd")) {
text = text + " " + strIMEI[i] + " "
+ strIMEI[i + 1];
System.out.println(text);
}
You are trying to access strIMEI[i+1] which will throw an error if your last element in strIMEI contains "abcd".

Java program that outputs an XML file - multiple issues

I'm new to this so please forgive me if I tagged something incorrectly or left something out.
I'm writing a java program (new to java also) - the purpose of the program is to generate an XML file with information from multiple databases.
The setup - I have sql.java which is the main class and has the main method. Sql.java calls methods located in the CCReturns.java class, GBLRets.java class, and CWSReturns.java class. Each method returns a string of XML containing pertinent information and then the main method in sql.java puts them all together in one string and creates an xml file.
Problem: One of my methods in CWSReturns should return a resultset containing 74 rows in all but is only returning the data from one of the rows. When I put this same code into the sql.java main method all 74 rows are returned in the console but the xml file only shows the data from one of the rows and all of the data from all of my other methods is repeated even though I only need it to output once.
What would be the best way to go about fixing this issue? I'm stumped.
Method in CWSReturns:

The elements in the "CLAIM_UNIT_INFO" node should repeat upwards of 74 times...

Inside the while loop you are returning. So it iterates only one time.
Make unitinfo in getUnitInfo() method as a StringBuilder and inside the while(rs.next) instead or returning append the unitinfo1 to unitinfo
public static String getUnitInfo(Connection connection, Statement stmt, ResultSet rs) throws SQLException, ClassNotFoundException
{
StringBuilder unitinfo = new StringBuilder();
...
while(rs.next()) {
...
unitinfo.append("<CLAIM_UNIT_INFO>");
//Create one large string that incorporates all of the above nodes
String unitinfo1 = CL_UNIT_YEAR + CL_UNIT_TYPE + CL_UNIT_SUB_TYPE + CL_UNIT_CATEGORY + CL_UNIT_IDENTIFIER +
CL_UNIT_NUM + CL_UNIT_MAKE + CL_UNIT_MODEL + CL_UNIT_VEH_ID + CL_UNIT_DESC1 + TAG_NUMBER + DAMLOC + DAMDESC +
UNIT_TYPE + UNIT_SUB_TYPE + UNIT_CATEGORY + UNIT_IDENTIFIER + UNIT_NUMBER + UNIT_YEAR + UNIT_MAKE +
UNIT_MODEL + VEH_ID + ITEM_DESC + COVERAGE_TYPE + DED_TYPE_CODE1 + DEDUCTIBLE1 + DED_TYPE_CODE2 +
DEDUCTIBLE2 + DED_TYPE_CODE3 + DEDUCTIBLE3 + LIMIT_TYPE1 + LIMIT1 + LIMIT_TYPE2 + LIMIT2 +
LIMIT_TYPE3 + LIMIT3 + LIMIT_TYPE4 + LIMIT4;
unitinfo.append(unitinfo1);
unitinfo.append("</CLAIM_UNIT_INFO>");
}
...
return unitinfo.toString();
}

As #SyamS mentioned you are returning inside of your loop.
If you don't want to combine all of the rows into one String: One way to fix this would be to store the String found in the loop into an ArrayList, and then return the ArrayList of String.
You would have to change the return type of your method, and handle iterating through the resulting ArrayList when you called the method.
public static ArrayList<String> getUnitInfo(...){
ArrayList<String> unitinfo = new ArrayList<String>();
...
while(...){
...
unitinfo.add(unitinfo1); // Instead of return
}
...
return unitinfo; // Only return at the end
}

The reason this is happening is because you have return unitinfo1 inside your while loop. So it is just returning after the first row has been populated.
You need to declare String unitinfo1 outside of the while loop, and append each line to the string during each iteration of the loop.
String unitinfo1;
while(condition)
{
unitinfo1.append(nextLine);
}
return unitinfo1;
