Java
'char' expression used in arithmetic context
Warning
New
Last modified: 03 December 2024 Reports expressions of the char
type used in addition or subtraction expressions.
Such code is not necessarily an issue but may result in bugs (for example, if a string is expected).
Example: int a = 'a' + 42;
After the quick-fix is applied: int a = (int) 'a' + 42;
For the String
context:
int i1 = 1;
int i2 = 2;
System.out.println(i2 + '-' + i1 + " = " + (i2 - i1));
After the quick-fix is applied:
System.out.println(i2 + "-" + i1 + " = " + (i2 - i1));
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
