Different ways to create objects in java

Question

I know this is very basic question but please read the full question first. Its bit confusing for me so I need all your help. We know that there are two ways of creating an object in java.

• use of " new " keyword and
• class.forName() .

But I came across some other ways also in a book to create an object which I am not able to understand. The keywords are

• newarray
• anewarray
• multianewarray

I am not getting any good study meterial on internet for these keywords. Please help me out. I am posting the link here. Please read the first 2 lines. http://www.artima.com/insidejvm/ed2/gcP.html

Answer 1

These are not keywords: these are JVM bytecode instructions.

Eg Java code new int [3][2] compiles into these bytecodes:

iconst_3
iconst_2
multianewarray [[I 2
