String Initialization using literals

Creating a String literal → JVM checks the String Constant Pool.

• Exists => Points to the same 'literal'
• Doesn't Exist => New instance created

String str = new String(); //null
String str = new String("Kya challa?")

New object created irrespective of whether the literal already exists or not
