Another relatively new addition to Java is the keyword assert It is used during program development to create an assertion, which is a condition that should be true during the execution of the program For example, you might have a method that should always return a positive integer value You might test this by asserting that the return value is greater than zero using an assert statement At run time, if the condition actually is true, no other action takes place However, if the condition is false, then an AssertionError is thrown Assertions are often used during testing to verify that some expected condition is actually met They are not usually used for released code The assert keyword has two forms The first is shown here: assert condition; Here, condition is an expression that must evaluate to a Boolean result If the result is true, then the assertion is true and no other action takes place If the condition is false, then the assertion fails and a default AssertionError object is thrown The second form of assert is shown here: assert condition : expr; In this version, expr is a value that is passed to the AssertionError constructor This value is converted to its string format and displayed if an assertion fails Typically, you will specify a string for expr, but any non-void expression is allowed as long as it defines a reasonable string conversion

Create a program to test whether the brick will automatically shut down after two minutes even while running a program that loops forever. Be sure to set your brick to use a value of 2 for the Sleep timer.

13:

d [!] address [/mask] This option specifies the destination IP address to check against When combined with an optional netmask, the destination IP can be compared against an entire netblock As with -s, the exclamation mark negates the rule, and the address and netmask can be abbreviated An example of its usage is

// Demonstrate assert class AssertDemo { static int val = 3; // Return an integer static int getnum() { return val--; } public static void main(String args[]) { int n; for(int i=0; i < 10; i++) { n = getnum(); assert n > 0; // will fail when n is 0 Systemoutprintln("n is " + n); } } }

To enable assertion checking at run time, you must specify the -ea option For example, to enable assertions for AssertDemo, execute it using this line:

This rule will allow all packets going through the FORWARD chain that are destined for the 10100930/24 network j target This option specifies an action to jump to These actions are referred to as targets in iptables parlance The targets that we ve seen so far have been ACCEPT, DROP, and RETURN The first two accept and drop packets, respectively The third is related to the creation of additional chains As we saw in the preceding section, it is possible for you to create your own chains to help keep things organized and to accommodate more complex

After compiling and running as just described, the program creates the following output: n is 3 n is 2 n is 1 Exception in thread "main" javalangAssertionError at AssertDemomain(AssertDemojava:17) In main( ), repeated calls are made to the method getnum( ), which returns an integer value The return value of getnum( ) is assigned to n and then tested using this assert statement:

This statement will fail when n equals 0, which it will after the fourth call When this happens, an exception is thrown

rules If iptables is evaluating a set of rules in a chain that is not built-in, the RETURN target will tell iptables to return back to the parent chain Using the earlier to_net10 example, when iptables reaches the -j RETURN, it goes back to processing the FORWARD chain where it left off If iptables sees the RETURN action in one of the built-in chains, it will execute the default rule for the chain Additional targets can be loaded via Netfilter modules For example, the REJECT target can be loaded with ipt_REJECT, which will drop the packet and return an ICMP error packet back to the sender Another useful target is ipt_REDIRECT, which can make a packet be destined to the NAT host itself even if the packet is destined for somewhere else i interface This option specifies the name of the interface on which a packet was received This is handy for instances where special rules should be applied if a packet arrives from a physical location, such as a DMZ interface For example, if eth1 is your DMZ interface and you want to allow it to send packets to the host at 10432, you can use
