Compact Computers is a small computer assembly company. Any customer currently has the following choices for a PC: (i) 800 MHz processor, 40 GB HDD, 128 MB RAM (ii) 1 GHz processor, 60 GB HDD, 256 MB RAM (iii) 1.2 GHz processor, 80 GB HDD, 512 MB RAM The use of what design pattern would ensure that only the legal combinations could be sold?

A Philadelphia based cable company is using J2EE for their Customer Management system. The system uses a combination of HTML and JSP for presentation. Java Servlets are used as Controllers. All Servlets have access to a ServletContext object, which functions as a Container to the shared resources of the Servlets. The ServletContext object best exemplifies what design pattern?

Compact Computers is a small computer assembly company. Its online application allows customers to pick and choose accessories to build their own PCs. The accessories are: i. Processor - 800Mhz, 1Ghz, 1.2Ghz ii. HDD - 40 GB, 60 GB, 80 GB iii. Memory - 128 MB, 256 MB, 512 MB Customers choose parts and quantities during the order. For example, a customer could choose a second HDD as a secondary hard drive or purchase additional RAM. What design pattern may be optimal for implementing a suitable design here?

package constructors; class R { R() { } } class S extends R { int p ; S() { this(10); super(); System.out.println("I am in Q"); } S(int p) { this.p = p; System.out.println("I am in Q with Argument"); } } public class TestConstructor4 { Q q = new Q(); }

package constructors; class A { A() { System.out.println("I am in A"); } } class B extends A { B() { System.out.println("I am in B"); } } class C extends B { C() { System.out.println("I am in C"); } } public class TestConstructor1 { public static void main(String[] args) { C c = new C(); } }

package constructors; class P { P(String a) { System.out.println("I am in P "+a); } } class Q extends P { Q() { System.out.println("I am in Q"); } } public class TestConstructor2 { Q q = new Q(); }

package constructors; class M { int i; M() { System.out.println("I am in M, No argument Constructor"); this(10); } M(int i) { this.i = i; System.out.println("I am in M, Constructor with Argument"); } } public class TestConstructor3 { M m = new M(); }

What is the output of the following code snippet ?? void main() { printf("%d", sizeof(2.0)); }
