Answer / abel

length and length( )
A) length variable:
length is an instance variable of type array. Array is an object, just like string, Object, JFrame, etc. The array class has an instance variable called length, when you say arrayName.length, you are getting the length of an array.
int student[] = new int[5];
System.out.println(student.length); // prints 5

length() method:
It is a method defined in String class. It gives the number of characters present in the string.

String str = "hello";
System.out.println(str.length()); // prints 5

Notice that in the first example made the length variable public, it can be accessed anywhere. In the second example it is private and cannot be accessed directly, so we provide a method which allows us to view the length variable.

It is like comparing two strings with == and equals(). equals() is a method call which takes more time than executing == operator.
