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());

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

In writeObject of FileOutputStream we declare one String Array that time error are occurs.
My Code is
writeObject(String[] str {"1"});
To begin with, 1 is not a String .
Also, your syntax is not correct to pass the array , try this way :
yourObjectOutputStream.writeObject(new String[] {"1"});
Or if you prefer
String[] str = new String[] {"1"};
yourObjectOutputStream.writeObject(str);

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())

Any ideas how to effeciently convert the String "TDMaturityReinvestOnNotSelected" to "TD Maturity Reinvest On Not Selected" using a java function?
Cheers

This brilliant answer to RegEx to split camelCase or TitleCase (advanced) should work nicely.
Below is an excerpt from that answer:
final String pattern = "(?<!(^|[A-Z]))(?=[A-Z])|(?<!^)(?=[A-Z][a-z])";
for (String w : "TDMaturityReinvestOnNotSelected".split(pattern))
{
System.out.println(w);
}
And the ouput to show it running:
Edit: You'll need to reassemble the split words with spaces, but that should be trivial to work out.

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.
