What is the difference between
String str = new String("abc");
and
String str = "abc";
ie what is the difference between String Literal and String object.
Ans:

In this example both string literals refer the same object:


String a = "abc"; 
String b = "abc";
System.out.println(a == b);  // true



Here, 2 different objects are created and they have different references:


String c = new String("abc");
String d = new String("abc");
System.out.println(c == d);  // false


String Literal uses constant pool memory whereas String Object refers the Heap memory. 


When we create string b it doesnot create another string but but use the reference of the a String.

What happens when you compile/run the following code: class MyClass { public static void main(String[] args) { new MyClass(); } Ans: It executes and create a object for that class without reference. The output of the program is nothing.
