class ColorException extends Exception {}
class WhiteException extends ColorException {}
class White {
void m1() throws ColorException {throw new WhiteException();}
void m2() throws WhiteException {}
public static void main (String[] args) {
White white = new White();
int a,b,d,f; a = b = d = f = 0;
try {white.m1(); a++;} catch (ColorException e) {b++;}
try {white.m2(); d++;} catch (WhiteException e) {f++;}
System.out.print(a+","+b+","+d+","+f);
}}

What is the result of attempting to compile and run the program?

a. Prints: 0,1,0,0
b. Prints: 1,1,0,0
c. Prints: 0,1,1,0
d. Prints: 1,1,1,0
e. Prints: 1,1,1,1
f. Compile-time error
g. Run-time error
h. None of the above

answer c.

why exception is not cought for method m2()?

thanks in advance.

void m2() throws WhiteException {} does not throw any exceptions.
 
Consider Paul's rocket mass heater.
