doubt on basics

[Krishna Srinivasan]

can anyone explain me about System.out.println(); in detail

Advance Thanx.

I don't know ...detail upto which extent is needed ur's side.....
But going through the inheritence tree should be quite detailed.
If that is so, start from Object --> PrintStream --> System.....and so on.
Thanks

[Uma Balu]

System --> Class present in the java.lang package
out --> static PrintStream object of the System class
println--> PrintStream method

[Mishra Anshu]

yes that is all ......but Uma didn't u see , he is a scjp1.4....
I think he has some other query......
He should ask some what clearly.....

I don't know what you really need, but you can read the java sources for more details. It should be obtained if you select to include java source when installing jdk.
I try to give some information here.
System.out is an instance of class PrintStream - you can find this in class java.lang.System. And class PrintStream has overloaded method println(), such as println(boolean x), println(char x)... Here is one of them:

  
public void println(char x) {
synchronized (this) {
    print(x);
    newLine();
}
}

You can see that it calls its own method print(char x). Here is the code:

    public void print(char c) {
write(String.valueOf(c));
    }

It first convert character 'c to a string, and eventually write it out by calling method write(String s). Method write(..) are also overloaded, one version is:

    private void write(String s) {
try {
    synchronized (this) {
ensureOpen();
textOut.write(s);
textOut.flushBuffer();
charOut.flushBuffer();
if (autoFlush && (s.indexOf('\n') >= 0))
    out.flush();
    }
}
catch (InterruptedIOException x) {
    Thread.currentThread().interrupt();
}
catch (IOException x) {
    trouble = true;
}
    }

textOut and charOut are the fundamental streams that do the real work.
You can see a chain of method calling from println() to print(), then to write(). All of these methods are overloaded, so System.out.println() can take different types of parameters.
Is this what you want?
