Java vs. C#

try/catch statement

Java
 
try/catch statement
static int F(int a, int b) {    
    if (b == 0)        
        throw new Exception("Divide by zero");   
        return a / b;
}
public static void main(String[] args) {    
    try {        
        System.out.println(F(5, 0));    
    }catch(Exception e) {   
        System.out.println("Error");   
    }
}


nested try/finally statement
class Test
{
    public static void main(String[] args) {
        while (true) {
            try {
                try {
                    System.out.println("Before break");
                    break;

            }
        }
        System.out.println("After break");
    }
}
prints:
   Before break
   Innermost finally block
   Outermost finally block
   After break


throw statement
