Concatenation with empty string
Reports empty string operands in string concatenations. Concatenation with the empty string can be used to convert non-String
objects or primitives into String
s, but it can be clearer to use a String.valueOf()
method call.
A quick-fix is suggested to simplify the concatenation.
Example:
void foo(int x, int y) {
String s = "" + x + " ; " + y;
}
After the quick-fix is applied:
void foo(int x, int y) {
String s = x + " ; " + y;
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
ConcatenationWithEmptyString
Use the Report only where empty strings can be removed without other changes option to ignore cases cases where removing the empty string will require adding a String.valueOf()
conversion of another operand.
Here you can find the description of settings available for the Concatenation with empty string inspection, and the reference of their default values.
