i have a json object and want to convert it to an int, but i get different numbers. On the first get the output is 1665750692735 (the right One), but on the getInt the output -696618113. Why?
Ok its because its an long. But how i get the long from the JSON Object?
JSON;
{"date":1665750692735,"name":"testDateTwo"}
Method:
public void add(JsonObject date) {
System.out.println((date.get("date")));
System.out.println((date.getInt("date")));
}
because the maximum value of an int is 2147483647,When long converts int, a data overflow occurs

I need to print Swedish words that contain unicode using Java
how can I do it?
for example
Text with Unicode:- \u228sk\u228da
Output: åskåda
Both of the following would work:
class Main {
public static void main(String args[]) {
System.out.println("åskåda");
System.out.println("\u00e5sk\u00e5da");
}
}
Note that you need to use the hex values and must take care of specifying the encoding when reading data (from disk or network)

How can I generate string const in z3 through java-api? For integer, there are ctx.mkInt(int a) generate an IntExpr with value a and ctx.mkIntConst("a") generate an IntExpr with name "a". However, for string, I can only find ctx.mkString("a"), which is just a SeqExpr with value "a" similar as ctx.mkInt. So what I want is something like ctx.mkStringConst("a") but there is no such function.
I find in python api, what I want is is simply str = String("a")
Try the following.
String variable_name="foo";
Expr variable = context.mkConst(context.mkSymbol(variable_name), context.mkStringSort());

Can anyone explain to me how to reverse a number start with zero in java. I trying to reverse a number 025 but output is only 52. But output should be 520
explanation much appreciated.
You are mixing types. "025" is not a number, it's a String. In a number you simply cannot distinguish between 25, 025, 0025, 00025, ... Implement your assignment as a String operation.
public String reverseString(String s) {
// put your code here
}
You may find very useful the Oracle tutorial on Strings here: https://docs.oracle.com/javase/tutorial/java/data/strings.html

I am getting this error while compiling my code. Please help me with this-
code is
mapConnectionProperties = new HashMap<String, Integer>();
mapConnectionProperties.put(mobileSeriesMappingDTO
.getExternalIP(), mobileSeriesMappingDTO.getExternalPort());
mobileSeriesMappingDTO.getExternalPort() is seemingly a String. Convert it to an Integer.
Integer.parseInt(mobileSeriesMappingDTO.getExternalPort())
Your mobileSeriesMappingDTO.getExternalPort() gives a String,
Transform it to an Integer with :
Integer.parseInt(mobileSeriesMappingDTO.getExternalPort())

I'm trying to set a integer datatype value on label (data type string).
I used "setText" method nut it display an error.
label.setText(String.valueOf(intValue));
label.setText(Integer.toString(intValue));
Not only for integers , String class have valueOf methods for almost all data types
String.valueOf(int);
Ex
label.setText(String.valueOf(5)); //example 5.Place your integer.
Reference : Check Oracle docs on Converting Strings to Numbers
label.setText(intValue+"");
Will do the trick.
