How to make a person confident that java has high performance capability?

Question

Please kindly illustrate how to prove to some one that java is a high performance language ?

Answer 1

The only real way to convince someone is to create a complex program and execute it under difficult conditions. In an extreme the Java can be compiled to run on a specific target.

High performance can only be evaluated on a particular platform and for a particular problem. There are places where Java will not be suitable (nuclear simulations, NSA decoding, etc.) but under normal application needs it does a pretty good job. HOwever as you can see from the other answers the only way to prove it is by demonstration

Answer 2

I really don't know what you mean by "high performance", but as far as portability is concerned, Java is a better candidate. Also, there is something in Programming called parallel programming, and Java can do parallel programming while C++ is unable to!

Hope this gives you a brief highlight!

Answer 3

Well, its not a high performance language. C is a high performance language. Java is like halfway between a script language and a compiled language. But it does look nice.

Answer 4

Show them a complex Java application, such as a game or some diagramming software. They'll see for themselves that performance is just fine. But be sure to use a recent JVM - 1.4.2 or later.

Answer 5

It isn't!

Unless you're making Java for graphics, then fine, it's excusable .. but please use C/++ for programming in general!

Java can also be decompiled to it's original source, C/++ cannot without 80% errors.

Answer 6

{
public static void main(String args[])
{
System.out.println("Hello World!");
}
}

That is almost sexy.
