'&&' is used for short-circuiting boolean expressions, which means that it will stop evaluating if the first operant is false but '&' won't.
This can be easier understood with an example:
int i = 0;
if( i < 10 && i++ < 20)
{
//some fancy stuff in here
}
first operant: i < 5
second operant: i++ < 20
In this case (using '&&'), if the first operant is evaluated to be false, it will stop and does not continue to evaluate the second operant.
If '&&' was replaced by '&,' even if the first operation is evaluated as false. It will still continue to evaluate the second operant before evaluating that the whole boolean is false, thus taking more time.

difference between constant and static variables in java
Java or Java SE comes with the standard library, with all the crazy classes to make life easy. Java Core does not come with most of these classes, so that it is a lot smaller.
both are mobile operating syms but sybm is more faster than the java
They are different versions. Java 5 is newer than Java 2. Think of it like the difference between the Playstation 1 and the Playstation 3.

java is a programming language/platform that embodies object oriented programming concepts. The question of what is the difference is like asking what is the difference between cars and a Volvo.
Java doesn't have pointers. C++ has pointers.

Windows is an operating system whereas Java is a programming language. They are entirely different.
