The result long value is exactly same as string argument in base However java supports autoboxing , so they both can be used interchangeably in most of the cases. We can use Long class toString method to get the string representation of long in decimal points.
Below code snippet shows you how to use it to convert long to string in java. So the string is always being returned in decimal format. We can use StringBuilder and StringBuffer append function to convert long to string. Here is a simple program where we will convert long to string and print it using all the different methods we saw above. Change the long value in above program to Octal or Hexadecimal format, you will notice that string representation is always on decimal format.
What if we want to convert long to string with different radix, not the default decimal point. Since the Java String class uses this char[] array internally; therefore, the length variable can not be exposed to the outside world. Hence, the Java developers created the length method, the exposes the value of the length variable.
One can also think of the length method as the getter method, that provides a value of the class field to the user. The internal implementation clearly depicts that the length method returns the value of then the length variable.
Since the length method gives the total number of characters present in the string; therefore, one can also check whether the given string is empty or not. The length method can also be used to find only the white spaces present in the string. Observe the following example. JavaTpoint offers too many high quality services.
