#30848 — Difference between new instance() and new () in java

Hi,


i have searched for difference between new intance() and new() in java.i am not getting any proper solution and real time prospectively.but i got only   theoretical knowledge.can you anyone tell me what is the difference and which real scenario we used that two things.


what i am understanding in new insatnce() and new() :

new instance() :
 It is used for run time and specified class loading like class.forname("FOO.class").newinstance();

new () :

It is used for compile time and as usual you know object creation like new FOO();


I don't know what is the exact difference for that.




Thanks
senthilkumaran

Short answer: if you don't know the difference, use /new/.

Slightly longer answer: /newinstance()/ is a part of Java's
reflection mechanism. Reflection is a way to analyze and
manipulate the class system at runtime, which can be very
useful in certain situations, but is not something you'll
be likely to use in day-to-day coding. Put it aside for now
and look back into it once you're familiar with the Java 
language.
