[英]which of these two block would catch more exceptions , Exception or RuntimeException
[英]This method throws two different exceptions. How could man catch the two exceptions and prints exception catched for both exception types to console?
public class CatchingExceptions {
private int erroneousMethod(int p) {
if (p == 0) {
throw new IllegalArgumentException();
}
int x = 0x01;
return p / (x >> Math.abs(p)); // this line will throw!
}
任務是實現以下方法來捕獲並打印兩個異常。
public void catchExceptions(int passthrough) {
erroneousMethod(passthrough); // will throw!
try{
????
} catch (IllegalArgumentException e){
System.out.println("???? ");
}
}
在try
塊中調用方法:
public void catchExceptions(int passthrough) {
try{
erroneousMethod(passthrough);
} catch (RuntimeException e) { // catches all unchecked exceptions
String message = e.getMessage() == null ? "" : (": " + e.getMessage());
System.out.println(e.getClass().getSimpleName() + ": " + message);
}
}
