String[] arr={"a","b","c"}

How to reduce the arr length by 1 by removing the last element without declaring a new array?

You can't reduce the array length by removing an array element. length is public final member of Array.


Thanks,<br />Murali...

String class implements immutable character strings, which are read-only once the string has been created and initialised ...their state cannot be changed...

String class implements immutable character strings

String is immutable. String keeps an array of characters which is mutable as any other array. But String don't have a method to modify this array and restrict subclassing String class by declaring the class final.

The interface String implements is CharSequence which is not mandating the implementor should be immutable.
 
It is sorta covered in the JavaRanch Style Guide.
