Here is the Java code equivalent of the given Kotlin code:
```
@Override
public void fillCompletionVariants(@NotNull CompletionParameters parameters, @NotNull CompletionResultSet result) {
// Get the current file
PsiFile file = parameters.getOriginalFile();
// Get the current cursor position
int offset = parameters.getOffset();
// Get the element at the current cursor position
PsiElement element = file.findElementAt(offset);
// If the element at the current cursor position is a string literal
if (element instanceof PsiLiteralExpression && element.getValue() instanceof String) {
String text = (String) element.getValue();
String prefix = text.substring(0, offset - element.getTextOffset());
// Asynchronously add code completion items
CompletableFuture<List<String>> future = CompletableFuture.supplyAsync(() -> {
// Implement the logic to search for predicted code asynchronously over the network here
// Return the list of predicted code
return searchPredictions(prefix);
});
// When the asynchronous operation is complete, add the results to the result set
future.thenAccept(predictions -> {
predictions.forEach(prediction -> {
result.addElement(LookupElementBuilder.create(prefix + " " + prediction));
});
});
}
}
// Implement the logic to search for predicted code asynchronously over the network here
// Return the list of predicted code
private List<String> searchPredictions(String prefix) {
// Implement the logic to search for predicted code asynchronously over the network here
// Return the list of predicted code
return Arrays.asList("Hello", "World");
}
```
