Need help please:)

Suppose you have the following simple class: public class Test \{ String a; // rest elided \} From the code snippets below, select the one that would add a default constructor that safely initializes the field of the test class shown above. public Test() \{\} (no need to initialize anything -- strings have a default non-null initial value) private Test(){a=";} public Test() { return; } public void Test() {a= ""; } public Test() {a= "'; } Suppose you have a Song class that looks like the following: public class Song \{ private String title; // \} Select the code snippet below is a valid getter method for the Song title field. public String getTitle(String aTitle) { return aTitle; } public void getTitle(String aTitle) { return aTitle; } public String getTitle() { return title; } public void getTitle() { return title; } A class can be thought of as a blueprint/schematic while an object is a concrete instantiation a class (done via the new keyword).
