Will a compilation error occur when dividing by zero in a try block if catch throws an exception and finally returns the string "finally"?

In Java, dividing by zero for integer types results in an ArithmeticException. If this occurs within a try block, and another exception is thrown in the catch block, and there is a return statement in the finally block, then the value from finally will be returned, and the exceptions will be suppressed.
Example:
public String test() {
try {
int a = 1 / 0; // ArithmeticException
} catch (Exception e) {
throw new RuntimeException("Error in catch");
} finally {
return "finally";
}
}
In this code, the method will return the string "finally" and will not throw an exception, because the return in finally overrides exceptions from try and catch. This will not cause a compilation error, but such behavior can lead to loss of error information and is considered bad practice.
