The type 'identifier' does not inherit from 'Throwable'
The compiler detected an invalid class argument used as an argument in a catch statement. When using a catch statement to handle exceptions, you must define it with a class derived from Throwable as a parameter. Ensure that the class you defined for the catch statement is derived from Throwable and compile again.
The following example illustrates this error:
public class Simple {
public void method1() {
try {
// do something meaningful
} catch (String s) {
// error: 'String' not a subclass
// of 'Throwable'
}
}
}
The following example illustrates the correct way to use the catch statement to trap exceptions:
public class Simple{
public void method1(int arg1){
try{
//do something here
if (arg1 == 0)
throw new myException(); //throw a valid exception object
}
catch(myException c){ //this is a valid exception object to catch
//handle exception here
}
}
}
class myException extends Throwable{
//class definition goes here
}
