in end of code is this error what problem? tried many fixes but no ones help
https://i.stack.imgur.com/jwosT.png
return (List<String>) ImmutableList.of();
The problem with this is that the type of ImmutableList.of() is determined before the cast is applied.
The type of ImmutableList.of() in that context is ImmutableList<Object>. An ImmutableList<Object> isn't an ImmutableList<String>.
I'm surprised you need any type hinting here:
return ImmutableList.of();

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

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())

Can you use strings in some way to define the source and target of files.move.
Heres the documentation http://docs.oracle.com/javase/tutorial/essential/io/move.html
According to the javadoc, you can not use strings as arguments for Files.move .
What seems to be a better solution for you, is using the rename method on File. Something like this:
File file = new File("/path/to/file/to/be/moved");
boolean moved = file.renameTo("/new/path/for/the/file");
if(!moved)
//Handle the error
Short answer is no: Files.move requires Path objects. That said, you can use Paths.get(str) to simply turn a String into a Path.
