You can traverse through the elements of many Java Collection objects because they provide a way to access their elements sequentially. What design pattern is used 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 U { U() { System.out.println("I am in U"); } } class V extends U { void V() { System.out.println("I am in V"); } } public class TestConstructor5 { public static void main(String[] args) { V v = new V(); } }

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(); }
