Consider the following classes: public class first { public void method2() { system. out. println("first2"); } public void method3() { method2(); }}public class second extends first { public void method2() { system. out. println("second2"); }}public class third extends second { public void method1() { system. out. println("third1"); super. method2(); } public void method2() { system. out. println("third2"); }}public class fourth extends first { public void method1() { system. out. println("fourth1"); } public void method2() { system. out. println("fourth2"); }}suppose the following variables are defined: first var1 = new second(); first var2 = new third(); first var3 = new fourth(); second var4 = new third(); object var5 = new fourth(); object var6 = new second(); indicate below the output that would be produced by each statement shown. if the statement produces more than one line of output, indicate the line breaks with slashes as in a/b/c to indicate three lines of output with a followed by b followed by c. if the statement causes an error, write the word error to indicate this. var1.method2(); var2.method2(); var3.method2(); var4.method2(); var5.method2(); var6.method2(); var1.method3(); var2.method3(); var3.method3(); var4.method3(); var5.method3(); var6.method3(); ((second) var4).method1(); ((third) var4).method1(); ((second) var5).method2(); ((first) var5).method3(); ((third) var5).method1(); ((first) var6).method3(); ((second) var6).method1(); ((second) var6).method3();

Usually, when we sniff packets, we are only interested certain types of packets. we can do that by setting filters in sniffing. scapy’s filter use the bpf (berkeley packet filter) syntax; you can find the bpf manual from the internet. set the following filters and demonstrate your sniffer program again (each filter should be set separately): (a) capture only the icmp packet. (b) capture any tcp packet that comes from a particular ip and with a destination port number 23. (c) capture packets comes from or to go to a particular subnet. you can pick any subnet, such as 128.230.0.0/16; you should not pick the subnet that your vm is attached to.
