java installation procedure..

hey guys,
i am new to java....
would you please help me how to compile and execute the java codes.
which java installation package should i install?

Welcome to JavaRanch

Have a look at the getting started part of the Java Tutorials. Download JDK 6 update 11. Don't use the JRE (it hasn't got a compiler) and don't use NetBeans at this stage.

It tells you in great detail what to do: the bit which most commonly causes trouble is setting the PATH. Please ask again if you have any problems.

hi ,
please anyone could help me...i have a problem in the compilation of the below given program.

public class puzz
{
public static void main(String args[])
{
dog[] d=new dog[6];
int x=0;
int y=1;
int result=0;

while(x<6)
{
dog[x]=new dog[];
d[x].v=y;
y=y*10;
x=X+1;
}
x=6;
while(x>0)
{
x=x-1;
result=result+d[x].do(x);
}
System.out.println("result is"+result)

}

}

class dog
{
int v;
public int do(int f)
{
if(v>100)
{
return v*f;

}
else
{
return v*(5-f);
}
}
}

the required output for the program is 543345.
