In this chapter you will learn:

1. How to convert long value to string

Convert long value to string

Converting long value to string is easy with the help of the following methods.

• String toString() returns a String object representing this Long's value.
• static String toString(long i) returns a String object representing the specified long.
• static String toString(long i, int radix) returns a string representation of the argument i in the radix.

The following code converts long value to string. Pay attention to the second conversion since it specifies the radix.

public class Main {
  public static void main(String[] args) {
    System.out.println(Long.toString(10));
    System.out.println(Long.toString(10,8));
  }// jav a  2  s  . c o m
}

The output:
