difference between String a; and String a=new String();? y do v need to assign memory to the variab..

Answer / saroj kumar biswal

String a;
jvm creates a reference & allocates memory for storing hashcode value

String a=new String();
jvm creates a object to String class in heap memory & returns the unique hexadecimal equivalent of that memory location which is stored in reference variable a as hashcode.

We dont need to assign memory to variable.because in java memory management is taken care by jvm automatically.Programmer need not worried about memory allocation issue.But yes jvm allocates memory for variable to store hashcode, if it is a referenced variable.If it is primitive type variable then jvm will not allocate extra memory for that variable.Because primitive types stored in object & there is memory allocated for object by jvm.
